Hi Prabhakar,

I want to take this opportunity to drop unnecessary functions, most of
the andes SBI calls were experimental/debugging features in kernel that
won't affact the boot flow.

You can still keep them in generic/renesas/rzfive.c. The renesas vendor
SBI call fid does not need to be the same as ours.

As for common Andes CSR which you separated into andes/ae350/common-platform.h
can be moved to generic/include/andes45.h.

Best regards,
Peter Lin
