AHCI: SATA drive not detected by GRUB payload for coreboot |

Dear GRUB folks,
as already mentioned, currently using coreboot with the GRUB payload on
the ASRock E350M1, the HDD connected over Serial ATA (SATA) at port 2,
or any other port, is not detected. Using an SSD instead it’s also *not*
detected.
This issue is present since at least last year and probably since the
rewrite of `grub-core/disk/ahci.c`. I was able to reproduce it with
latest master, that means commit 5e74a3e6 (disk/ahci: Use defines
`GRUB_ATA_STATUS_BUSY` and `GRUB_ATA_STATUS_DRQ`).
Doing `rmmod ahci` and `insmod ahci` the connected drive is mostly
detected.
Below are my changes for debugging. I added resetting the host bus
adapter (HBA) and debug statements for port 2.

Judging from the following register values
disk/ahci.c:267: tfd[2]: 80
disk/ahci.c:269: cmd[2]: 2006
disk/ahci.c:271: st[2]: 123
disk/ahci.c:273: err[2]: 40d0000
I’d say a port reset is missing. The ASRock E350M1 uses AMD’s AGESA code
which, I think, also does some SATA initialization. That might be the
reason, that coreboot/GRUB payload users do not experience this with
Intel hardware.
Thanks,
Paul
