If this is ported from Linux, please include Linux commit SHA from which 
this is ported.

Can this do the same thing as Aquatia PHY and load the PHY firmware from 
filesystem on block device instead , using the blk* or fs* commands ? 
Then the hard-coded filesize and co. won't be necessary.

If you need board specific loading override, implement __weak default 
loading from file on filesystem by default (see what Aquatia does) and 
then override the loading function on board or architecture level.

U-Boot really needs a proper generic firmware loader, because this 
firmware stuff keeps showing up more and more, but I cannot ask you to 
write one only because of this PHY ... but if you are up for a challenge ...
