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,
