[LinuxBIOS] [PATCH] Initial support for the MSI MS-6178 (i810-based)

[Uwe Hermann]

Hi,

here's an initial patch for the MSI MS-6178 mainboard.

It boots up to a login prompt, but there are a number of issues
which need to be fixed before we can call this fully supported.

I'll post a list of working and non-working parts later, need to do more
tests...

One major issue is that the booting (and operation afterwards) is _really_
slow, a full boot takes more than 10 or 20 minutes!
I suspect RAM init problems or cache (L1/L2) problems, but I haven't yet
found out what's really going on.

Full boot log of LinuxBIOS + the original BIOS attached.

I guess (from looking at the boot log diffs) that this may be the reason
for the slow boot, but how do I fix it?

   CPU: L1 I cache: 16K, L1 D cache: 16K
  -CPU: L2 cache: 128K

(i.e., it seems the L2 cache is never enabled when using LinuxBIOS)

Here's the SPD dump of the RAM I used (64 MB in slot 0):
