X-Git-Tag: v2010.12-rc2~53^2~2^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0fc43a417c4ba5ab63dad6736a18f3bf7008f35f;p=platform%2Fkernel%2Fu-boot.git

armv7, beagle: Second SDRAM bank don;t work

since commit 3667cbeed5e3c4067e624e52a916b1ebb02c8f05
on beagle board the second sdram bank didn;t longer
work. Since this patch sdram settings just get copied
from bank a, but CMD_NOP, CMD_PRECHARGE, CMD_AUTOREFRESH
are not executed and after that mr register is also
not updated. This patch adds this for the bank b.
