MIPS: Cleanup and Fixup of compressed kernel support 2010-01-12T17:19:29+00:00 Wu Zhangjin wuzhangjin@gmail.com 2009-12-10T14:55:13+00:00 d4d9a553d7b96e18fcfbd0b8fb5f803b3a27e4e6 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.

MIPS: Add support for GZIP / BZIP2 / LZMA compressed kernel images 2009-12-17T01:56:56+00:00 Wu Zhangjin wuzhangjin@gmail.com 2009-10-14T10:12:16+00:00 1b93b3c3e94be2605759735a89fc935ba5f58dcf 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 vmlinuz Have 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 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 vmlinuz

Have 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 cleanups

and 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.
