2cb4fade0e mvsata: fix ide_preinit for missing disks
Consider that ide_preinit() succeed if at least one port is successfully
initialized. This allows to iniatialize IDE support on a board with two
SATA ports but a single hard disk available.

d3497138ff mvsata_ide: adjust port init sequence
mvsata_ide_initialize_port(): adjust init sequence (SStatus
should be checked only after all writes to SControl) and
return success/failure to ide_preinit().

Also, as some tests showed init durations in the hundreds
of us, raise the time-out to 01 ms to be on the safe side.

39419ce589 ide: add mvsata_ide driver
This driver only provides initialization code; actual driving
is done by cmd_ide.c using the ATA compatibility mode of the
Marvell SATAHC controller.
