Hi Pavel,
The ahci.c is a ahci driver using pci interface, while dwc_asata is not.
u-boot don't have a pure ahci driver now, thus we have to reuse some
ahci parts from ahci.c in dwc_asata.c.
Thanks~~
Yours
Terry

No, there are not evident reasons !
dwc_asata was inserted to add SATA support for Freescale MX5 family, and I
missed that a similar driver was already in u-boot. dwc_ahsata was ported from
Freescale's u-boot, and linked only for MX5 / MX6 SOCs. I think it is a very
good idea to merge the two drivers (dwc_ahsata seems an updated version of the
original driver), thanks to note this !
Best regards,
Stefano Babic
