Thank you for your detailed review.
I will resubmit this patch with new soc patch.

OK, but some recent patches use DRIVER_  naming.

CONFIG_DRIVER_TI_EMAC
CONFIG_DRIVER_AX88180

Is it not the preferred style?

I had submitted a v3 of this driver which removed unnecessary volatiles
according to the warnings told by checkpatch.pl.

http://lists.denx.de/pipermail/u-boot/2009-July/055421.html

Please ignore it, since I need to resubmit a new patch later.

Is it preferred way?
No driver in driver/net/ uses calloc.

I don't have a strong opinion, but don't think the 'DRIVER' part adds 
anything useful, so I guess remove.

Agreed. Please do not use 'DRIVER'.
