-# Makefile for making ELF bootable images for booting on CHRP
-# using Open Firmware.
-#
-# Geert Uytterhoeven September 1997
-#
-# Based on coffboot by Paul Mackerras
-# Simplified for ppc64 by Todd Inglett
-#
-# NOTE: this code is built for 32 bit in ELF32 format even though
-# it packages a 64 bit kernel. We do this to simplify the
-# bootloader and increase compatibility with OpenFirmware.
-#
-# To this end we need to define BOOTCC, etc, as the tools
-# needed to build the 32 bit image. These are normally HOSTCC,
-# but may be a third compiler if, for example, you are cross
-# compiling from an intel box. Once the 64bit ppc gcc is
-# stable it will probably simply be a compiler switch to
-# compile for 32bit mode.
-# To make it easier to setup a cross compiler,
-# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
-# in the toplevel makefile.

- 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.

- 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
- progress is possible or if there was not enough room in the output buffer

- 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
- the error code Z_DATA_ERROR instead of trying to allocate a larger window.
-
- If next_out is not null, the library will use this buffer for the history
- buffer; the buffer must either be large enough to hold the entire output
- data, or have at least 1<<windowBits bytes. If next_out is null, the
