Zheng, way to go! I am not knowledgeable enough to review, but thank you
very much for this contribution.

What H8SCM board is that? Searching for this on the WWW there seem to be
several ones. Just H8SCM [1], H8SCM-F [2], H8SCM-O [3]? Probably just
the plain one.

What was tested with this board? Are all features supported? Have you
had time yet to set up a page in the Wiki how to build an image and what
is supported?

Thanks,

Paul

Hi guys,

I, too, wonder what exact board that is. the H8SCM-F seems to have an
additional fast-ethernet IPMI port on the EC, also it seems that it
uses a socketed ROM.
Unfortunately neither the datasheet, nor the available (small)
pictures show the H8SCM well enough to see if it too has a socket for
the ROM, but it doesn't seem that way. Can you confirm this?

Anyway, it's awesome to see such a recent professional board
supported, thanks a lot Zheng and AMD!

Just a little FYI for those interested in this board:
As of AMDs announcement to support coreboot even more, they listed the
H8SCM-F-O (commonly sold as H8SCM-F which appears to be the same in
any case) as socket C32 reference board for coreboot. On pictures it
often shows a SO16 flash socket - unfortunately I have not been able
to acquire one that really has the socket. One retailer was even nice
enough to check his stock for me, every single board has the flash
soldered on.

Some boards have an SPI flash header where you can attach an external
flash programmer (one low cost option would be the bus pirate at ~$30).

Without a header it might still be possible to apply a programmer to the
chip directly using clips, but that's less convenient (and has the risk
of failing if the board circuitry messes up the signal too much)

I generally find external flashers more convenient than having to take
care that I flash the right flash with the right image at all times and
then hot swapping chips.

I think that the board was developed with an external programmer and
testclip method of flashing.

Zheng,
Please do an svn copy from the the starting mainboard and then apply
the changes of this patch. This helps keep the history. Let me know if
you need a hand with that.
