[U-Boot] [PATCH] common: remove unaligned access error in bootmenu_getoption()

[Lan Yixun (dlan)]

From: "Lan Yixun (dlan)" <dennis.yxun at gmail.com>

Some ARM compilers may emit code that makes unaligned accesses when
faced with constructs such as:

    char name[12] = "bootmenu_";

same fix as commit: 064d55f8bc8d7d205ed0be6abb6717e92eeb7cad

=========================================================
data abort

    MAYBE you should read doc/README.arm-unaligned-accesses
