-          This is the processor type of your CPU. This information is used for
-          optimizing purposes. In order to compile a kernel that can run on
-          all x86 CPU types (albeit not optimally fast), you can specify
-          "386" here.
-
-          The kernel will not necessarily run on earlier architectures than
-          the one you have chosen, e.g. a Pentium optimized kernel will run on
-          a PPro, but not necessarily on a i486.
-
-          Here are the settings recommended for greatest speed:
-          - "386" for the AMD/Cyrix/Intel 386DX/DXL/SL/SLC/SX, Cyrix/TI
-          486DLC/DLC2, UMC 486SX-S and NexGen Nx586.  Only "386" kernels
-          will run on a 386 class machine.
-          - "486" for the AMD/Cyrix/IBM/Intel 486DX/DX2/DX4 or
-          SL/SLC/SLC2/SLC3/SX/SX2 and UMC U5D or U5S.
-          - "586" for generic Pentium CPUs lacking the TSC
-          (time stamp counter) register.
-          - "Pentium-Classic" for the Intel Pentium.
-          - "Pentium-MMX" for the Intel Pentium MMX.
-          - "Pentium-Pro" for the Intel Pentium Pro.
-          - "Pentium-II" for the Intel Pentium II or pre-Coppermine Celeron.
-          - "Pentium-III" for the Intel Pentium III or Coppermine Celeron.
-          - "Pentium-4" for the Intel Pentium 4 or P4-based Celeron.
-          - "K6" for the AMD K6, K6-II and K6-III (aka K6-3D).
-          - "Athlon" for the AMD K7 family (Athlon/Duron/Thunderbird).
-          - "Crusoe" for the Transmeta Crusoe series.
-          - "Efficeon" for the Transmeta Efficeon series.
-          - "Winchip-C6" for original IDT Winchip.
-          - "Winchip-2" for IDT Winchip 2.
-          - "Winchip-2A" for IDT Winchips with 3dNow! capabilities.
-          - "GeodeGX1" for Geode GX1 (Cyrix MediaGX).
-          - "CyrixIII/VIA C3" for VIA Cyrix III or VIA C3.
-          - "VIA C3-2 for VIA C3-2 "Nehemiah" (model 9 and above).

+          This is the processor type of your CPU. This information is used for
+          optimizing purposes. In order to compile a kernel that can run on
+          all x86 CPU types (albeit not optimally fast), you can specify
+          "386" here.
+
+          The kernel will not necessarily run on earlier architectures than
+          the one you have chosen, e.g. a Pentium optimized kernel will run on
+          a PPro, but not necessarily on a i486.
+
+          Here are the settings recommended for greatest speed:
+          - "386" for the AMD/Cyrix/Intel 386DX/DXL/SL/SLC/SX, Cyrix/TI
+          486DLC/DLC2, UMC 486SX-S and NexGen Nx586.  Only "386" kernels
+          will run on a 386 class machine.
+          - "486" for the AMD/Cyrix/IBM/Intel 486DX/DX2/DX4 or
+          SL/SLC/SLC2/SLC3/SX/SX2 and UMC U5D or U5S.
+          - "586" for generic Pentium CPUs lacking the TSC
+          (time stamp counter) register.
+          - "Pentium-Classic" for the Intel Pentium.
+          - "Pentium-MMX" for the Intel Pentium MMX.
+          - "Pentium-Pro" for the Intel Pentium Pro.
+          - "Pentium-II" for the Intel Pentium II or pre-Coppermine Celeron.
+          - "Pentium-III" for the Intel Pentium III or Coppermine Celeron.
+          - "Pentium-4" for the Intel Pentium 4 or P4-based Celeron.
+          - "K6" for the AMD K6, K6-II and K6-III (aka K6-3D).
+          - "Athlon" for the AMD K7 family (Athlon/Duron/Thunderbird).
+          - "Crusoe" for the Transmeta Crusoe series.
+          - "Efficeon" for the Transmeta Efficeon series.
+          - "Winchip-C6" for original IDT Winchip.
+          - "Winchip-2" for IDT Winchip 2.
+          - "Winchip-2A" for IDT Winchips with 3dNow! capabilities.
+          - "GeodeGX1" for Geode GX1 (Cyrix MediaGX).
+          - "CyrixIII/VIA C3" for VIA Cyrix III or VIA C3.
+          - "VIA C3-2 for VIA C3-2 "Nehemiah" (model 9 and above).

-          their addressable memory into ST and TT sections.  The TT section
-          (up to 512MB) is the main memory; the ST section (up to 4MB) is
-          accessible to the built-in graphics board, runs slower, and is

-
-          This enables support for using (parts of) ST-RAM as swap space,

-          performance if you have lots of alternate RAM (compared to the size

-          memory. ST-RAM will remain as ultra-fast swap space. On the other
-          hand, it allows much improved dynamic allocations of ST-RAM buffers
-          for device driver modules (e.g. floppy, ACSI, SLM printer, DMA

- * New Nov 1997: Use ST-RAM as swap space!
- *
- * In the past, there were often problems with modules that require ST-RAM
- * buffers. Such drivers have to use __get_dma_pages(), which unfortunately
- * often isn't very successful in allocating more than 1 page :-( [1] The net
- * result was that most of the time you couldn't insmod such modules (ataflop,
- * ACSI, SCSI on Falcon, Atari internal framebuffer, not to speak of acsi_slm,
- * which needs a 1 MB buffer... :-).
- *
- * To overcome this limitation, ST-RAM can now be turned into a very
- * high-speed swap space. If a request for an ST-RAM buffer comes, the kernel
- * now tries to unswap some pages on that swap device to make some free (and
- * contiguous) space. This works much better in comparison to
- * __get_dma_pages(), since used swap pages can be selectively freed by either
- * moving them to somewhere else in swap space, or by reading them back into
- * system memory. Ok, there operation of unswapping isn't really cheap (for
- * each page, one has to go through the page tables of all processes), but it
- * doesn't happen that often (only when allocation ST-RAM, i.e. when loading a
- * module that needs ST-RAM). But it at least makes it possible to load such
- * modules!
- *
- * It could also be that overall system performance increases a bit due to
- * ST-RAM swapping, since slow ST-RAM isn't used anymore for holding data or
- * executing code in. It's then just a (very fast, compared to disk) back
- * storage for not-so-often needed data. (But this effect must be compared
- * with the loss of total memory...) Don't know if the effect is already
- * visible on a TT, where the speed difference between ST- and TT-RAM isn't
- * that dramatic, but it should on machines where TT-RAM is really much faster
- * (e.g. Afterburner).
- *
- *   [1]: __get_free_pages() does a fine job if you only want one page, but if
- * you want more (contiguous) pages, it can give you such a block only if
- * there's already a free one. The algorithm can't try to free buffers or swap
- * out something in order to make more free space, since all that page-freeing
- * mechanisms work "target-less", i.e. they just free something, but not in a
- * specific place. I.e., __get_free_pages() can't do anything to free
- * *adjacent* pages :-( This situation becomes even worse for DMA memory,
- * since the freeing algorithms are also blind to DMA capability of pages.

+ *             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

+ * This port was done on an MBX board with an 860.  Right now I only
+ * support an ELF compressed (zImage) boot from EPPC-Bug because the
+ * code there loads up some registers before calling us:
+ *   r3: ptr to board info data
+ *   r4: initrd_start or if no initrd then 0
+ *   r5: initrd_end - unused if r4 is 0
+ *   r6: Start of command line string
+ *   r7: End of command line string
+ *
+ * I decided to use conditional compilation instead of checking PVR and
+ * adding more processor specific branches around code I don't need.
+ * Since this is an embedded processor, I also appreciate any memory
+ * savings I can get.
+ *
+ * The MPC8xx does not have any BATs, but it supports large page sizes.
+ * We first initialize the MMU to support 8M byte pages, then load one
+ * entry into each of the instruction and data TLBs to map the first
+ * 8M 1:1.  I also mapped an additional I/O space 1:1 so we can get to
+ * the "internal" processor registers before MMU_init is called.
+ *
+ * The TLB code currently contains a major hack.  Since I use the condition
+ * code register, I have to save and restore it.  I am out of registers, so
+ * I just store it in memory location 0 (the TLB handlers are not reentrant).
+ * To avoid making any decisions, I need to use the "segment" valid bit
+ * in the first level table, but that would require many changes to the
+ * Linux page directory/table functions that I don't want to do right now.
+ *
+ * I used to use SPRG2 for a temporary register in the TLB handler, but it
+ * has since been put to other uses.  I now use a hack to save a register
+ * and the CCR at memory location 0.....Someday I'll fix this.....

-   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.

-
-   zalloc must return Z_NULL if there is not enough memory for the object.
-   On 16-bit systems, the functions zalloc and zfree must be able to allocate
-   exactly 65536 bytes, but will not be required to allocate more than this
-   if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS,
-   pointers returned by zalloc for objects of exactly 65536 bytes *must*
-   have their offset normalized to zero. The default allocation function
-   provided by this library ensures this (see zutil.c). To reduce memory
-   requirements and avoid any allocation of 64K objects, at the expense of
-   compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h).
-
-   The fields total_in and total_out can be used for statistics or
-   progress reports. After compression, total_in holds the total size of
-   the uncompressed data and may be saved for use in the decompressor

-  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
-  when Z_FINISH is used. In the Z_DATA_ERROR case, the application may then
-  call inflateSync to look for a good compression block.  */

-   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
