Subject: arm:mmc:goni/exynos: Fix wrong mmc base register devices offset.
X-Git-Tag: v2013.10-rc3~5^2^2~1
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7324907082b94679fe57ba0067c1079a03cbfd89;p=oweals%2Fu-boot.git

arm:mmc:goni/exynos: Fix wrong mmc base register devices offset.

On s5pc1xx mmc devices offset is multiply of 0x100000,
wrong value was 0x10000. Register offset always points
to mmc 0 before this change.

Add macro definition of mmc dev register offset to s5pc1xx and
exynos mmc.
