Fix VMLINUZ_LOAD_ADDRESS calculation to be based on the length of
vmlinux.bin, the actual uncompressed kernel binary.Previously it was based on the length of KBUILD_IMAGE (the unstripped ELF
vmlinux), which is bigger than vmlinux.bin. As a result, vmlinuz was
loaded into a memory address higher then actually needed - a problem for
small memory platforms.Signed-off-by: Shmulik Ladkani

The compressed vmlinux.bin is only a temp file so it's ok to use the same
suffix .z for them (.gz,.lzo,.lzma...) to remove several lines and simpify
the maintenance (no need to add the "suffix_$(xxx) := suffix" line).Signed-off-by: Wu Zhangjin

POSIX requires $(()) arithmetic in sh only to have long
arithmetic so on 32-bit sh binaries might do only 32-bit arithmetic but
the arithmetic done in arch/mips/boot/compressed/Makefile needs 64-bit.I play with the AR7 platform, so VMLINUX_LOAD_ADDRESS is
0xffffffff94100000, and for an example 4MiB kernel
VMLINUZ_LOAD_ADDRESS is made out to be:
----
alex@berk:~$ bash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))'
ffffffff94500000
alex@berk:~$ dash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))'
80000000003fffff
----The former is obviously correct whilst the later breaks things royally.
Fortunately working with only the lower 32bit's works for both bash and
dash:
----
$ bash -c 'printf "%x\n" $((0x94100000 + 0x400000))'
94500000
$ dash -c 'printf "%x\n" $((0x94100000 + 0x400000))'
94500000
----So, we can split the original 64bit string to two parts, and only
calculate the low 32bit part, which is big enough (1GiB kernel sizes
anyone?) for a normal Linux kernel image file, now, we calculate the
VMLINUZ_LOAD_ADDRESS like this:1. if present, append top 32bit of VMLINUX_LOAD_ADDRESS" as a prefix
2. get the sum of the low 32bit of VMLINUX_LOAD_ADDRESS + VMLINUX_SIZEThis patch fixes vmlinuz kernel builds on systems where only a
32bit-only math shell is available.Patch Changelog:
Version 2
- simplified method by using 'expr' for 'substr' and making it work
with dash once again
Version 1
- Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error
of "make clean"
- Consider more cases of the VMLINUX_LOAD_ADDRESS

o Remove the .initrd section. The initrd section was already handled
when vmlinux was linked.
o Discard .MIPS.options, .options, .pdr, .reginfo, .comment and .note
sections. If .MIPS.options is not removed, kernels compiled with gcc
3.4.6 will not boot.
o Clean up the file format.
o Remove several other unneeded sections.Tested with GCC 3.4.6 and 4.4.1 with and without initrd.

This patch helps to generate smaller kernel images for linux-MIPS,
Here is the effect when using lzma:
$ ls -sh vmlinux
7.1M vmlinux
$ ls -sh vmlinuz
1.5M vmlinuzHave tested the 32bit kernel on Qemu/Malta and 64bit kernel on FuLoong
Mini PC. both of them work well. and also, tested by Alexander Clouter
on an AR7 based Linksys WAG54Gv2, and by Manuel Lauss on an Alchemy
board.This -v2 version incorporate the feedback from Ralf, and add the
following changes:1. add .ecoff, .bin, .erec format support
2. only enable it and the debug source code for the machines we tested
3. a dozen of fixups and cleanupsand if you want to enable it for your board, please try to select
SYS_SUPPORTS_ZBOOT for it, and if the board have an 16550 compatible
uart, you can select SYS_SUPPORTS_ZBOOT_UART16550 directly. and then
sending the relative patches to Ralf.Tested-by: Manuel Lauss

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
