The build command i use is this:
alias mymake='make ARCH=ARM CROSS_COMPILE=arm-none-linux-gnueabi- V=1 -j2'


though on a fresh clone, I seem to have run into a wierd issue ->
MAKEALL seems to build things fine, but if I:
mymake distclean
rm -rvf *
git reset --hard
mymake omap3_sdp3430_config
mymake

CPU type

for some wierd reason, it does not seem to take the include/config.mk
file (where the defines are present)..

now, if i do a local clone of the cloned directory, it builds just fine!
gotta dig at it a little more..
