[ECOS] Redboot compilation for mips

["Philippe De Swert" <philippedeswert at scarlet dot be>]

Hello,

I do not manage to compile redboot for one of the demo platforms (I do not
need specific support for that target however, as I am trying to find out how
easily it compiles, size etc... before eventually porting it to a new board).

After the configuration with ecosconfig I get the following error during the
build. (same for atlas_mips32_4kc and malta_mips32_4kc, I tried those two configs)

make -r -C hal/mips/arch/v2_0 build

make[1]: Leaving directory `/home/fille/bootloader/build/hal/mips/arch/v2_0'
make: *** [build] Error 2

I looked through the bug database but I cannot find a related bug/error
report. The only thing I could dig up out on the mailing list, which could
probabely cause this is the toolchain. Do I really need an mips-elf toolchain
for this (instead of a general mips-linux- one)? The used toolchain compiles
kernel and userland (uClibc, busybox, gdb) fine.

Thank you for helping,

Philippe
