Sorry for not explaining it good enough:
I don't observe any alignment problems. mach-socfpga can do unaligned
accesses as well. This driver does CPU based copy, but since it transfers
words, not bytes, I guess on other platforms, the CPU might fail when trying
to read a word from an unaligned pointer.

Vignesh added this about a year ago and from that commit message, it
seems like he was observing alignment errors on his TI platform.
Also, those commits have a reviewed-by tag from you and Jagan.

For me, reverting these patches would be OK as well, but I guess Vinesh's
TI platform kind of needs them?
