Makes sense - That's basically what I had in mind. My concern is with
the bit that made no sense to me - the non-multiplatform version of the
same. At the moment, we have the default xx_SINGLE for ARCH_VT8500.
Would I need to add an additional xx_SINGLE variant for each different
version?
We would need ARCH_WM8505 (To cover VT8500/WM8505/WM8650 ARM926),
ARCH_WM8750 (for ARMv6) and ARCH_WM8850 (for ARMv7).
Do I need a ARCH_WM8750_SINGLE, ARCH_WM8850_SINGLE etc for each one to
allow use to continue using earlyprintk?
