From: Michael Pratt <mpr...@chromium.org>
Since snow has a different memory configuration than peach, split the
configuration between the 5250 and 5420. Exynos 5420 supports runtime
memory configuration detection, and can make the determination between 4
and 7 banks at runtime.
Include the bank size with the number of banks for context to make the
number of banks meaningful.
