This is the first commit for the u-boot zylonite port. The following has be
done so far: * created zylonite board dir (based on lubbock) * extended some - but not all pxa sources and headers for Intel Monahans support (CONFIG_CPU_MONAHANS) * created Makefile zylonite target + MAKEALL entry * added some debug nonsense, remove later, grep for mk@tbd Status: compiles (eldk-4.0), and can be started with BDI, but runs forever and doesn't halt at breakpoints. Hmmm...
