-Creation of the self-extracting compressed kernel image (vmlinuz)
------------------------------------------------------------------
-$Id: README,v 1.1 2001/12/17 13:59:27 bjornw Exp $
-
-This can be slightly confusing because it's a process with many steps.
-
-The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
-by that makefile into text and data binary files, vmlinux.text and
-vmlinux.data.
-
-Those files together with a ROM filesystem can be catted together and
-burned into a flash or executed directly at the DRAM origin.
-
-They can also be catted together and compressed with gzip, which is what
-happens in this makefile. Together they make up piggy.img.
-
-The decompressor is built into the file decompress.o. It is turned into
-the binary file decompress.bin, which is catted together with piggy.img
-into the file vmlinuz. It can be executed in an arbitrary place in flash.
-
-Be careful - it assumes some things about free locations in DRAM. It
-assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
-so it puts its code at 0x40700000, and initial stack at 0x40800000.

- * Rescue code, made to reside at the beginning of the
- * flash-memory. when it starts, it checks a partition
- * table at the first sector after the rescue sector.
- * the partition table was generated by the product builder
- * script and contains offsets, lengths, types and checksums
- * for each partition that this code should check.
- *
- * If any of the checksums fail, we assume the flash is so
- * corrupt that we cant use it to boot into the ftp flash
- * loader, and instead we initialize the serial port to
- * receive a flash-loader and new flash image. we dont include
- * any flash code here, but just accept a certain amount of
- * bytes from the serial port and jump into it. the downloaded
- * code is put in the cache.
- *
- * The partitiontable is designed so that it is transparent to
- * code execution - it has a relative branch opcode in the
- * beginning that jumps over it. each entry contains extra
- * data so we can add stuff later.
- *
- * Partition table format:
- *
- * Code transparency:
- *
- * 2 bytes [opcode 'nop']
- * 2 bytes [opcode 'di']
- * 4 bytes [opcode 'ba <offset>', 8-bit or 16-bit version]
- * 2 bytes [opcode 'nop', delay slot]
- *
- * Table validation (at +10):
- *
- * 2 bytes [magic/version word for partitiontable - 0xef, 0xbe]
- * 2 bytes [length of all entries plus the end marker]
- * 4 bytes [checksum for the partitiontable itself]
- *
- * Entries, each with the following format, last has offset -1:
- *
- * 4 bytes [offset in bytes, from start of flash]
- * 4 bytes [length in bytes of partition]
- * 4 bytes [checksum, simple longword sum]
- * 2 bytes [partition type]
- * 2 bytes [flags, only bit 0 used, ro/rw = 1/0]
- * 16 bytes [reserved for future use]
- *
- * End marker
- *
- * 4 bytes [-1]
- *
- * 10 bytes [0, padding]
- *
- * Bit 0 in flags signifies RW or RO. The rescue code only bothers
- * to check the checksum for RO partitions, since the others will
- * change their data without updating the checksums. A 1 in bit 0
- * means RO, 0 means RW. That way, it is possible to set a partition
- * in RO mode initially, and later mark it as RW, since you can always
- * write 0's to the flash.
- *
- * During the wait for serial input, the status LED will flash so the
- * user knows something went wrong.
