+ Inflate deflated (PKZIP's method 8 compressed) data. (compress
+ with the gzip -3 option which will compress it in a compatible
+ format).
+
+ The compression method searches for as much of the current string of bytes
+ (up to a length of 258) in the previous 32 K bytes. If it doesn't find any
+ matches (of at least length 3), it codes the next byte. Otherwise, it
+ codes the length of the matched string and its distance backwards from
+ the current position. There is a single Huffman code that codes both
+ single bytes (called "literals") and match lengths. A second Huffman
+ code codes the distance information, which follows a length code. Each
+ length or distance code actually represents a base value and a number
+ of "extra" (sometimes zero) bits to get to add to the base value. At
+ the end of each deflated block is a special end-of-block (EOB) literal/
+ length code. The decoding process is basically: get a literal/length
+ code; if EOB then done; if a literal, emit the decoded byte; if a
+ length then get the distance and emit the referred-to bytes from the
+ sliding window of previously emitted data.
+
+ There are (currently) three kinds of inflate blocks: stored, fixed, and
+ dynamic. The compressor deals with some chunk of data at a time, and
+ decides which method to use on a chunk-by-chunk basis. A chunk might
+ typically be 32 K or 64 K. If the chunk is incompressible, then the
+ "stored" method is used. In this case, the bytes are simply stored as
+ is, eight bits per byte, with none of the above coding. The bytes are
+ preceded by a count, since there is no longer an EOB code.
+
+ If the data is compressible, then either the fixed or dynamic methods
+ are used. In the dynamic method, the compressed data is preceded by
+ an encoding of the literal/length and distance Huffman codes that are
+ to be used to decode this block. The representation is itself Huffman
+ coded, and so is preceded by a description of that code. These code
+ descriptions take up a little space, and so for small blocks, there is
+ a predefined set of codes, called the fixed codes. The fixed method is
+ used if the block codes up smaller that way (usually for quite small
+ chunks), otherwise the dynamic method is used. In the latter case, the
+ codes are customized to the probabilities in the current block, and so
+ can code it much better than the pre-determined fixed codes.
+
+ The Huffman codes themselves are decoded using a multi-level table
+ lookup, in order to maximize the speed of decoding plus the speed of
+ building the decoding tables. See the comments below that precede the
+ lbits and dbits tuning parameters.

+
+
+/*
+ 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. Similarly, 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.

+ (The EOB code is shorter than other codes because fixed blocks are
+ generally short. So, while a block always has an EOB, many other

+ lookup, and so will not require that too many bits be pulled from

+ 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.

++ *
++ * 1) We handle one interrupt and return, sitting in a loop and moving across
++ * all the pending IRQ bits in the cause register is _NOT_ the answer, the
++ * common case is one pending IRQ so optimize in that direction.
++ *
++ * 2) We need not check against bits in the status register IRQ mask, that
++ * would make this routine slow as hell.
++ *
++ * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
++ * between like BSD spl() brain-damage.
++ *
++ * Furthermore, the IRQs on the MIPS board look basically (barring software
++ * IRQs which we don't use at all and all external interrupt sources are
++ * combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
++ *
++ * MIPS IRQ Source
++ * -------- ------
++ * 0 Software (ignored)
++ * 1 Software (ignored)
++ * 2 Combined hardware interrupt (hw0)
++ * 3 Hardware (ignored)
++ * 4 Hardware (ignored)
++ * 5 Hardware (ignored)
++ * 6 Hardware (ignored)
++ * 7 R4k timer (what we use)
++ *
++ * Note: On the SEAD board thing are a little bit different.
++ * Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
++ * wired to UART1.
++ *
++ * We handle the IRQ according to _our_ priority which is:
++ *
++ * Highest ---- R4k Timer
++ * Lowest ---- Combined hardware interrupt
++ *
++ * then we just return, if multiple IRQs are pending then we will just take
++ * another exception, big deal.

++ *
++ * These are const, typedef, and api definitions for tnetd73xx.
++ *
++ * NOTES:
++ * 1. This file may be included into both C and Assembly files.
++ * - for .s files, please do #define _ASMLANGUAGE in your ASM file to
++ * avoid C data types (typedefs) below;
++ * - for .c files, you don't have to do anything special.
++ *
++ * 2. This file has a number of sections for each SOC subsystem. When adding
++ * a new constant, find the subsystem you are working on and follow the
++ * name pattern. If you are adding another typedef for your interface, please,
++ * place it with other typedefs and function prototypes.
++ *
++ * 3. Please, DO NOT add any macros or types that are local to a subsystem to avoid
++ * cluttering. Include such items directly into the module's .c file or have a
++ * local .h file to pass data between smaller modules. This file defines only
++ * shared items.
