[PATCH 1/2] ARM: EXYNOS4: Enhancement of System MMU driver
[PATCH 2/2] ARM: EXYNOS4: Implement Clock gating for System MMU

Cc'ed Marek.

As I said before, Marek's SystemMMU driver has some problems.

One is that it allocates 4MB virtual memory at once. It is really a problem
because, the device memory manager must knows the peculiarity and handles
it. Otherwise, page tables can be overwritten...

Anyway, I think Marek's initial idea is good esp., clock handling.
But now, this looks better for its enhancement and as we know if required,
we can improve this later.

Applied, thanks.

Best regards,
Kgene.
