sys/arch/arm/sunxi/sunxi_sata.c: revision 1.2
(applied to sys/arm/allwinner/awin_ahcisata.c)
Use new magic values from linux for DMACR. While I couldn't measure any
significant difference with my old, slow laptop drive, linux commiter claims
a 3x write performance boost (from 40 to 120MB/s) and 200MB/s read with
a ssd.
