[ Upstream commit bea6a94a279bcbe6b2cde348782b28baf12255a5 ]
Starting with following patch MIPS Malta is not able to boot: | commit 79edff12060fe7772af08607eff50c0e2486c5ba | Author: Rob Herring robh@kernel.org | scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9
The reason is the alignment test added to the fdt_ro_probe_(). To fix this issue, we need to make sure that fdt_buf is aligned.
Since the dtc patch was designed to uncover potential issue, I handle initial MIPS Malta patch as initial bug.
