CRIS: Merge machine dependent boot/compressed and boot/rescue
Merge the machine dependent boot directories for v10 and v32. This avoids some code duplication and eases the way for further merging later on. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

1Creation of the self-extracting compressed kernel image (vmlinuz)
2-----------------------------------------------------------------
3$Id: README,v 1.1 2001/12/17 13:59:27 bjornw Exp $
4
5This can be slightly confusing because it's a process with many steps.
6
7The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
8by that makefile into text and data binary files, vmlinux.text and
9vmlinux.data.
10
11Those files together with a ROM filesystem can be catted together and
12burned into a flash or executed directly at the DRAM origin.
13
14They can also be catted together and compressed with gzip, which is what
15happens in this makefile. Together they make up piggy.img.
16
17The decompressor is built into the file decompress.o. It is turned into
18the binary file decompress.bin, which is catted together with piggy.img
19into the file vmlinuz. It can be executed in an arbitrary place in flash.
20
21Be careful - it assumes some things about free locations in DRAM. It
22assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
23so it puts its code at 0x40700000, and initial stack at 0x40800000.
