OK, so places like these will need different handling, and should
then be based on some idlest flag that gets set during the init
based on cpu_is_omap24xx() || cpu_is_omap3430() || cpu_is_omap3630().
Have you looked at defining cpu_is_ti816x() based on features?
Something like:
#define cpu_is_ti816x() (cpu_is_omap34xx() && \
(omap3_has_xyz())
Where xyz is based on some runtime detected flag, just like
we do for sgx and iva.

Tony
