[U-Boot] Unaligned data transfers?

[Tor Krill]

Hi, 

I have a question regarding (disk) transfers. For example Sata read and
write takes an unspecified address which very well could be an unaligned
byte address.

Many DMA-controllers though require 16 or 32bit alignments for
transfers.

Is it safe to assume that the address is correct or bail out with an
error message if source/destinaton address isn't correctly aligned for
the underlaying HW?
