This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
Exynos support.
sparsemem is currently not supported in multiplatform.
Is this still true as of today?
Otherwise looks fine.
sparsemem is still not supported in multiplatform, but after I looked
at it in more detail, I came to the conclusion that there is no
reason why it couldn't be. It just needs testing so we are confident
that it doesn't break other platforms, and we need to find good
platform-independent values for MAX_PHYSMEM_BITS and SECTION_SIZE_BITS
to put into asm/memory.h, since we can't have them set in mach/memory.h
for multiplatform.
Looking at my patch again now, I would actually prefer to kill off
the single-platform support for exynos right away. I don't see
any reason to keep it now, and it complicates the test matrix.
That would be the best option, assuming that it wouldn't introduce
feature regressions. Unfortunately there is still ongoing work on
cpufreq driver to make it multiplatform-aware, so dropping single
platform support right now would introduce at least this one regression.
Thomas, is there any progress on new version of Exynos cpufreq rework
series?
Best regards,
Tomasz
