I previously worked with U-Boot on ARM processors. The ARM Kconfig is
already quite crowded with both board and ARM specific configuration
entries. That's the reason behind this patch, trying to avoid mixing
both processor and board specific entries.
At the moment, there are only two boards and therefore no real need for
this patch, so I am fine with dropping this patch.

Thanks,
