Thanks!
If it requires plat/cpu.h, it should actually be limited to CONFIG_ARCH_OMAP,
otherwise we will get the same problem on non-OMAP ARM builds. From what
I can tell, the problem is the clocks_init function, which is the only
part that is not completely generic.
The trivial workaround would be to enclose the "#include <plat/cpu.h>"
statement in #ifdef CONFIG_ARCH_OMAP, but with the common clock code
in place, we should probably be able to come up with a better solution
that works independent of the omap platform.
