description:
Pad .sdata section to a 4-byte boundary so that the .image section
is always aligned.  This makes md_root_loadaddr always 4 byte aligned.
Without this, may get an un-aligned access trap before we even print
anything on the console which was a pain in the neck to debug since so
early in the bootstrap the CPU usually just halts on exceptions.
