The controllers look to all intents and purposes just like regular ATA
controllers (unless you want to initialise them from scratch), so there's
not much to do other than make sure the controller is recognised by the
driver. There's one there alraeady:

devi% grep SATA /sys/src/9/pc/sdata.c
		case (0x3149<<16)|0x1106:	/* VIA VT8237 SATA/RAID */
devi% 

and it has on it

devi# cat /dev/sdC0/ctl
inquiry ST380013AS
