Hi all,

There is a problem with the ck804 code in the tree when it comes to SATA
support. I've observed this on a tyan s2891, and it has been confirmed by
folks with a sun ultra40.

This patch changes the southbridge/nvidia/ck804/ck804_early_setup.c file and
enables one extra SATA port. I've tested this on real hardware (tyan s2891).

There is a very similar file called
southbridge/nvidia/ck804/ck804_early_setup_car.c which seems to be used by

  tyan/s2895
  sunw/ultra40

I don't have access to a s2895, but YH thinks that all sata ports should work
on that board. It would be great if someone could verify that.

I'm not 100% sure why both the ck804_early_setup.c and the
ck804_early_setup_car.c file are included in the mainboards/sunw/ultra40/
tree; probably only one of those files is actually used.

I've spent quite a bit of time with 'dumpio' and tried to match register
values between the proprietary BIOS and LinuxBIOS, but to no avail. If
someone has ideas to get port 1 working on both sata controllers, that would
be great.

Thanks,
Ward.

The ck804 code in the LB tree does not properly initialize all SATA ports.
The situation is currently as follows for boards with 4 SATA ports:

* sata controller 0: both ports 100% dead (no drives detected)
* sata controller 1: port 0 ok; port 1 sees drive but times out when trying
  to access it

The attached patch fixes port 0 on controller 0; port 1 on both controllers 
is still half-broken (as in it sees the drive initially but times out when 
trying to access it).

This patch will affect the boards that use the 
southbridge/nvidia/ck804/ck804_early_setup.c file:

  sunw/ultra40
  tyan/s2891
  tyan/s2892
  asus/a8n_e
