-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.
