Is this just an issue in 3.2-rt, or did you see this issue in the 3.0-rt
release too. I used your attached config and crossed compiled with arm:

$ /usr/local/gcc-4.5.2-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version
arm-unknown-linux-gnueabi-gcc (GCC) 4.5.2

and it finished fine with 3.0-rt, but when I compiled against both
3.2-rt1 and 3.2-rt3, I got the same error:

arch/arm/mach-imx/built-in.o: In function `imx31_soc_init':
/work/rt/rt.git/arch/arm/mach-imx/mm-imx3.c:186: undefined reference to `mx31_revision'
make[1]: *** [.tmp_vmlinux1] Error 1
make: *** [sub-make] Error 2

Which is not the error you saw. I'm curious to what I did wrong.

Thanks,
