Subject: arm: mvebu: Hang if ddr3_init() fails
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=7e1c0d0dca7fc382bb0a857e15019e7033b80fd2;p=u-boot.git

arm: mvebu: Hang if ddr3_init() fails

If ddr3_init() fails then DDR was not initialized and we cannot load and
execute U-Boot. We cannot continue, we cannot do anything in this case, so
hang.
