Hey Sunil,

Two quick comments while I think of them..

btw, about half of this series redundantly puts "ACPI:" or "RISC-V:
ACPI:" into $subject. None of commits that mention ACPI after the last :
should mention ACPI in the prefix IMO, it's just noise.

For example, this one should be something like:
RISC-V: enable ACPI in defconfig

This needs to go into the arch Kconfig file, where it will be selected.
Check what arm64 does if you are not sure what I mean.

Hopefully I'll get a chance to look at the rest of this this week
sometime,
Conor.
