That's a fair implementation.  There is going to be a bit of work
going into getting the 64 bit SCM un-stubbed.  So I can respin to incorporate
your comments or we can wait for the unstubbing.

So if QCOM_SCM is selected by a consumer then the dependencies here will
be met and the correct implementation will be chosen, as these aren't
possible to deselect?


I guess that's an okay approach, so:

Can we not start doing stuff like this.  Use the Kconfig to control what
you build, not the Makefile system.

config QCOM_SCM_32
def_bool y
depends on QCOM_SCM && ARM

config QCOM_SCM_64
def_bool y
depends on QCOM_SCM && ARM64

and then use those in the makefile.

Arnd, Kevin, Olof,

Please hold off on this until the comments I made on the patch in this
