SII3124-2

[Rune Torgersen]

Has anybody been successful in getting a SII3124-2 based SATA controller
to work under PPC?

I have a eval board that I tried on two different freescale boards (a
MPC8266ADS board and a MPC8560ADS board).
Kernel 2.6.16.16.

Here is the relevant output from the kernel.

ata1: SATA max UDMA/100 cmd 0xD1010000 ctl 0x0 bmdma 0x0 irq 115
ata2: SATA max UDMA/100 cmd 0xD1012000 ctl 0x0 bmdma 0x0 irq 115
ata3: SATA max UDMA/100 cmd 0xD1014000 ctl 0x0 bmdma 0x0 irq 115
ata4: SATA max UDMA/100 cmd 0xD1016000 ctl 0x0 bmdma 0x0 irq 115
ata1: SATA link down (SStatus 0)
scsi0 : sata_sil24
ata2: SATA link up 3.0 Gbps (SStatus 123)
sata_sil24 ata2: SRST failed, disabling port
scsi1 : sata_sil24
ata3: SATA link down (SStatus 0)
scsi2 : sata_sil24
ata4: SATA link down (SStatus 0)
scsi3 : sata_sil24

I added debug output to see the content of the Command Error register.
It is set to 26 which according to the datasheet for the 3124-1 (I am
running a -2), is PLDCMDERRORMASTERABORT, "A PCI Master Abort occurred
while the SiI3124 was fetching a Port Request Block (PRB) from host
memory."
