Hi Florian, hi devs
I just saw that you have kexec-tools running on mipsel. (great news :-)
I know that it is running as well for armeb, but it requires a small
patch against the kernel headers.
I tried hard to express it as an openwrt-style patch, but didn't
succeed yet. Can somebody help me?
part a)
in
staging_dir/toolchain-armeb_gcc4.1.2/armeb-linux-uclibc/sys-include/asm/
a symlink is needed: arch -> arch-ixp4xx
probably not ixp4xx but something like ${BOARD}
part b)
The patch needed against the kernel comes here, but it needs to be
applied *before* the kernel-includes are moved to the staging dir,
essentially
staging_dir/toolchain-armeb_gcc4.1.2/armeb-linux-uclibc/sys-include/asm/memory.h
is the file that needs to be patched.
