The method used in this patch is the same as what is currently used by the
other IBM EMAC PHY interfaces (eg. config IBM_EMAC_ZMII etc). I'm happy to
send a patch to update all of those as well for consistency but that would
mean adding what each platform requires into EMACS Kconfig as well.
Personally I think it is nicer to keep the definitions of what each platform
requires in one place (ie. arch/powerpc/platforms/44x/Kconfig) as it is
consistent with what we do for other 44x drivers, however I am happy to use
the above method if people think it's better.
Alternatively we could do something like this:
config IBM_EMAC_RGMII_WOL
bool
default y if COMPILE_TEST
default n
This would leave the platform dependencies as they are currently but still
allow compile testing.
