FYI.
My Cubieboard2 with any revisions of ahcisata_core.c does not recognize
my ST9500325AS 2.5inch hard drive (powerd from cb2 board) at boot, but
it does by "drvctl -r -a ata_hl atabus0" after boot.
I tried to increase 2nd arg of ahci_exit_fis() around WDCTL_RST
from 100 to 3000, then my cb2 recognizes my ST9500325AS at boot.
When this harddrive is powerd from external power supply, not from cb2,
it is recognized at boot without modifying ahcisata_core.c.

I changed power supply for my cb2 from 5V 3000mA to 5V 4A but
same result.
