+    will resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() always provides as much output as possible
+    (until there is no more input data or no more space in the output buffer).
+
+  Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating the next_* and avail_* values accordingly.
+  The application can consume the uncompressed output when it wants, for
+  example when the output buffer is full (avail_out == 0), or after each
+  call of inflate().
+
+    If the parameter flush is set to Z_PARTIAL_FLUSH or Z_PACKET_FLUSH,
+  inflate flushes as much output as possible to the output buffer. The
+  flushing behavior of inflate is not specified for values of the flush
+  parameter other than Z_PARTIAL_FLUSH, Z_PACKET_FLUSH or Z_FINISH, but the
+  current implementation actually flushes as much output as possible
+  anyway.  For Z_PACKET_FLUSH, inflate checks that once all the input data
+  has been consumed, it is expecting to see the length field of a stored
+  block; if not, it returns Z_DATA_ERROR.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+  is never required, but can be used to inform inflate that a faster routine
+  may be used for the single inflate() call.
+
+    inflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if the end of the

+  produced, Z_DATA_ERROR if the input data was corrupted, Z_STREAM_ERROR if
+  the stream structure was inconsistent (for example if next_in or next_out

+   Notes beyond the 1.93a appnote.txt:
+
+   1. Distance pointers never point before the beginning of the output
+      stream.
+   2. Distance pointers can point back across blocks, up to 32k away.
+   3. There is an implied maximum of 7 bits for the bit length table and
+      15 bits for the actual data.
+   4. If only one code exists, then it is encoded using one bit.  (Zero
+      would be more efficient, but perhaps a little confusing.)  If two
+      codes exist, they are coded using one bit each (0 and 1).
+   5. There is no way of sending zero distance codes--a dummy must be
+      sent if there are none.  (History: a pre 2.0 version of PKZIP would
+      store blocks with no distance codes, but this was discovered to be
+      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
+      zero distance codes, which is sent as one code of zero bits in
+      length.
+   6. There are up to 286 literal/length codes.  Code 256 represents the
+      end-of-block.  Note however that the static length tree defines
+      288 codes just to fill out the Huffman codes.  Codes 286 and 287
+      cannot be used though, since there is no length base or extra bits
+      defined for them.  Similarily, there are up to 30 distance codes.
+      However, static trees define 32 codes (all 5 bits) to fill out the
+      Huffman codes, but the last two had better not show up in the data.
+   7. Unzip can check dynamic Huffman blocks for complete code sets.
+      The exception is that a single code would not be complete (see #4).
+   8. The five bits following the block type is really the number of
+      literal codes sent minus 257.
+   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
+      (1+6+6).  Therefore, to output three times the length, you output
+      three codes (1+1+1), whereas to output four times the same length,
+      you only need two codes (1+3).  Hmm.
+  10. In the tree reconstruction algorithm, Code = Code + Increment
+      only if BitLength(i) is not zero.  (Pretty obvious.)
+  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
+  12. Note: length code 284 can represent 227-258, but length code 285
+      really is 258.  The last length deserves its own, short code
+      since it gets used a lot in very redundant files.  The length
+      258 is special since 258 - 3 (the min match length) is 255.
+  13. The literal/length and distance code bit lengths are read as a
+      single stream of lengths.  It is possible (and advantageous) for
+      a repeat code (16, 17, or 18) to go across the boundary between
+      the two sets of lengths.

+   Huffman code decoding is performed using a multi-level table lookup.
+   The fastest way to decode is to simply build a lookup table whose
+   size is determined by the longest code.  However, the time it takes
+   to build this table can also be a factor if the data being decoded
+   is not very long.  The most common codes are necessarily the
+   shortest codes, so those codes dominate the decoding time, and hence
+   the speed.  The idea is you can have a shorter table that decodes the
+   shorter, more probable codes, and then point to subsidiary tables for
+   the longer codes.  The time it costs to decode the longer codes is
+   then traded against the time it takes to make longer tables.
+
+   This results of this trade are in the variables lbits and dbits
+   below.  lbits is the number of bits the first level table for literal/
+   length codes can decode in one step, and dbits is the same thing for
+   the distance codes.  Subsequent tables are also less than or equal to
+   those sizes.  These values may be adjusted either when all of the
+   codes are shorter than that, in which case the longest code length in
+   bits is used, or when the shortest code is *longer* than the requested
+   table size, in which case the length of the shortest code in bits is
+   used.
+
+   There are two different values for the two tables, since they code a
+   different number of possibilities each.  The literal/length table
+   codes 286 possible values, or in a flat code, a little over eight
+   bits.  The distance table codes 30 possible values, or a little less
+   than five bits, flat.  The optimum values for speed end up being
+   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
+   The optimum values may differ though from machine to machine, and
+   possibly even between compilers.  Your mileage may vary.

+ * This is a three step process that will also work when booting from
+ * a Flash PROM normally located in high memory.
+ *
+ * First, the entire image is loaded into some high memory address.
+ * This is usually at or above 0x02000000.  This is done by a network
+ * boot function supported by the board or a debugger over BDM port.
+ *
+ * Second, the start up function here will relocate the decompress
+ * function to run at the link address of 0x01000000.
+ *
+ * Last, the decompression function will reloate the initrd, zImage, and
+ * the residual data to locations under 8 Meg.  This is necessary because
+ * the embedded kernel start up uses 8 Meg translations to access physical
+ * space before the MMU is enabled.  Finally, the zImage is uncompressed

+ * When reading the configuration space, if something does not respond
+ * the bus times out and we get a machine check interrupt.  So, the
+ * good ol' exception tables come to mind to trap it and return some
+ * value.
+ *
+ * On an error we just return a -1, since that is what the caller wants
+ * returned if nothing is present.  I copied this from __get_user_asm,
+ * with the only difference of returning -1 instead of EFAULT.
+ * There is an associated hack in the machine check trap code.
+ *
+ * The QSPAN is also a big endian device, that is it makes the PCI
+ * look big endian to us.  This presents a problem for the Linux PCI
+ * functions, which assume little endian.  For example, we see the
+ * first 32-bit word like this:
+ *	------------------------
+ *	| Device ID | Vendor ID |
+ *	------------------------
+ * If we read/write as a double word, that's OK.  But in our world,
+ * when read as a word, device ID is at location 0, not location 2 as
+ * the little endian PCI would believe.  We have to switch bits in
+ * the PCI addresses given to us to get the data to/from the correct
+ * byte lanes.
+ *
+ * The QSPAN only supports 4 bits of "slot" in the dev_fn instead of 5.
+ * It always forces the MS bit to zero.  Therefore, dev_fn values
+ * greater than 128 are returned as "no device found" errors.
+ *
+ * The QSPAN can only perform long word (32-bit) configuration cycles.
+ * The "offset" must have the two LS bits set to zero.  Read operations
+ * require we read the entire word and then sort out what should be
+ * returned.  Write operations other than long word require that we
+ * read the long word, update the proper word or byte, then write the
+ * entire long word back.
+ *
+ * PCI Bridge hack.  We assume (correctly) that bus 0 is the primary
+ * PCI bus from the QSPAN.  If we are called with a bus number other
+ * than zero, we create a Type 1 configuration access that a downstream
+ * PCI bridge will interpret.

+#    Description:

+#      the "image" and "initrd" section header information. It then
+#      rewrites the input ELF file with assigned globals to an output
+#      file.
+#
+#      An input file, "irSectStart.txt" has the memory address of
+#      'irSectStart'. The irSectStart memory address is used to find
+#      the global variables in the ".data" section of the ELF file.
+#      The 'irSectStart' and the above global variables are defined
+#      in "irSect.c".

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.

-   Huffman code decoding is performed using a multi-level table lookup.
-   The fastest way to decode is to simply build a lookup table whose
-   size is determined by the longest code.  However, the time it takes
-   to build this table can also be a factor if the data being decoded
-   is not very long.  The most common codes are necessarily the
-   shortest codes, so those codes dominate the decoding time, and hence
-   the speed.  The idea is you can have a shorter table that decodes the
-   shorter, more probable codes, and then point to subsidiary tables for
-   the longer codes.  The time it costs to decode the longer codes is
-   then traded against the time it takes to make longer tables.
-
-   This results of this trade are in the variables lbits and dbits
-   below.  lbits is the number of bits the first level table for literal/
-   length codes can decode in one step, and dbits is the same thing for
-   the distance codes.  Subsequent tables are also less than or equal to
-   those sizes.  These values may be adjusted either when all of the
-   codes are shorter than that, in which case the longest code length in
-   bits is used, or when the shortest code is *longer* than the requested
-   table size, in which case the length of the shortest code in bits is
-   used.
-
-   There are two different values for the two tables, since they code a
-   different number of possibilities each.  The literal/length table
-   codes 286 possible values, or in a flat code, a little over eight
-   bits.  The distance table codes 30 possible values, or a little less

-  Performs one or both of the following actions:
-
-  - Decompress more input starting at next_in and update next_in and avail_in
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), next_in is updated and processing
-    will resume at this point for the next call of inflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly.  inflate() always provides as much output as possible
-    (until there is no more input data or no more space in the output buffer).
-
-  Before the call of inflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating the next_* and avail_* values accordingly.
-  The application can consume the uncompressed output when it wants, for
-  example when the output buffer is full (avail_out == 0), or after each
-  call of inflate().
-
-    If the parameter flush is set to Z_PARTIAL_FLUSH or Z_PACKET_FLUSH,
-  inflate flushes as much output as possible to the output buffer. The
-  flushing behavior of inflate is not specified for values of the flush
-  parameter other than Z_PARTIAL_FLUSH, Z_PACKET_FLUSH or Z_FINISH, but the
-  current implementation actually flushes as much output as possible
-  anyway.  For Z_PACKET_FLUSH, inflate checks that once all the input data
-  has been consumed, it is expecting to see the length field of a stored
-  block; if not, it returns Z_DATA_ERROR.
-
-    inflate() should normally be called until it returns Z_STREAM_END or an
-  error. However if all decompression is to be performed in a single step
-  (a single call of inflate), the parameter flush should be set to
-  Z_FINISH. In this case all pending input is processed and all pending
-  output is flushed; avail_out must be large enough to hold all the
-  uncompressed data. (The size of the uncompressed data may have been saved
-  by the compressor for this purpose.) The next operation on this stream must
-  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
-  is never required, but can be used to inform inflate that a faster routine
-  may be used for the single inflate() call.
-
-    inflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if the end of the
-  compressed data has been reached and all uncompressed output has been
-  produced, Z_DATA_ERROR if the input data was corrupted, Z_STREAM_ERROR if
-  the stream structure was inconsistent (for example if next_in or next_out
-  was NULL), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR if no

-   size (the size of the history buffer).  It should be in the range 8..15 for
-   this version of the library (the value 16 will be allowed soon). The
-   default value is 15 if inflateInit is used instead. If a compressed stream
-   with a larger window size is given as input, inflate() will return with

-

- * This code is loaded by the ROM loader at some arbitrary location.
- * Move it to high memory so that it can load the kernel at 0x0000.
- *
- * This is a three step process that will also work when booting from
- * a Flash PROM normally located in high memory.
- *
- * First, the entire image is loaded into some high memory address.
- * This is usually at or above 0x02000000.  This is done by a network
- * boot function supported by the board or a debugger over BDM port.
- *
- * Second, the start up function here will relocate the decompress
- * function to run at the link address of 0x01000000.
- *
- * Last, the decompression function will reloate the initrd, zImage, and
- * the residual data to locations under 8 Meg.  This is necessary because
- * the embedded kernel start up uses 8 Meg translations to access physical
- * space before the MMU is enabled.  Finally, the zImage is uncompressed
- * to location 0 and we jump to it.
- *
- * On the MBX,
- *              R1 - Stack pointer at a high memory address.
- *              R3 - Pointer to Board Information Block.
- *              R4 - Pointer to argument string.
- *              Interrupts masked, cache and MMU disabled.
- *
- *		...and the first and second functions listed above are
- *			done for us (it knows ELF images).
- *
- * For other embedded boards we build the Board Information Block.

- * When reading the configuration space, if something does not respond

- *
- * On an error we just return a -1, since that is what the caller wants
- * returned if nothing is present.  I copied this from __get_user_asm,
- * with the only difference of returning -1 instead of EFAULT.
- * There is an associated hack in the machine check trap code.
- *
- * The QSPAN is also a big endian device, that is it makes the PCI
- * look big endian to us.  This presents a problem for the Linux PCI
- * functions, which assume little endian.  For example, we see the
- * first 32-bit word like this:
- *	------------------------
- *	| Device ID | Vendor ID |
- *	------------------------
- * If we read/write as a double word, that's OK.  But in our world,
- * when read as a word, device ID is at location 0, not location 2 as
- * the little endian PCI would believe.  We have to switch bits in
- * the PCI addresses given to us to get the data to/from the correct
- * byte lanes.
- *
- * The QSPAN only supports 4 bits of "slot" in the dev_fn instead of 5.
- * It always forces the MS bit to zero.  Therefore, dev_fn values
- * greater than 128 are returned as "no device found" errors.
- *
- * The QSPAN can only perform long word (32-bit) configuration cycles.
- * The "offset" must have the two LS bits set to zero.  Read operations
- * require we read the entire word and then sort out what should be
- * returned.  Write operations other than long word require that we
- * read the long word, update the proper word or byte, then write the
- * entire long word back.
- *
- * PCI Bridge hack.  We assume (correctly) that bus 0 is the primary
- * PCI bus from the QSPAN.  If we are called with a bus number other
- * than zero, we create a Type 1 configuration access that a downstream
- * PCI bridge will interpret.
