Fix various issues on MSI MS7135 board.
- w83627thf is strapped to 0x4e, not 0x2e - there's no device 9 on PCI-E x1 bus, it should be device 0 - add mptable entries for AGR slot, based on info in user manual - enable floppy drive controller so that some legacy VGA ROMs will work

Little confused by this. Why does the floppy drive controller have to be enabled for VGA??

I think this might be a 'feature' of the proprietary VGA ROM... Who knows why - there's no source...
Thanks, Ward.

Yeah, I found that a RV370 board I have was working when the superio address was wrong, because the floppy controller was in the power-on-reset state of enabled. When I corrected the superio address, and the FDC got disabled as instructed, the VGA BIOS did weird things I don't exactly recall and didn't work. I then tried enabling the FDC again and found that this made the VGA BIOS work again. I have no idea why it wants to touch the floppy controller, but I have to let it or it won't work.

LDN 6 is undocumented in the datasheet, might even not exist. Did you test if removing the line has problematic effects? Or do you have a reason to believe there's something on that LDN?

I don't think I've really tested it. Does having a LDN unlisted in Config.lb mean it doesn't get touched? If that's the case that LDN should just be omitted there. It probably is unimplemented. (It is implemented in the W83627EHG, apparently. But i have a THG on this board.)

Just a side note, if the superIO is similar to W83627EHG then you could use virtual LDNs for the different functionality in same LDN which are sharing same enable byte. (I did it for the W83627EHG).

Huh, but I don't think this is the case here.

In logical device 7 and 9 yes. If you want to enable at least something, you need to use virtual LDNs.

Hmm I added it at least to devel info.

Committed current patch in r3279 for now, as it fixes a few issues. Please post another patch for additional fixes and improvements.
Note that I dropped LDN 6, it's not available in *THF either, I checked the datasheet.

Can you merge that page somewhere into http://www.coreboot.org/Developer_Manual#Serial_output_and_the_Super_I.2FO please (if you agree to license the content under the GPLv2-or-later, as the rest of the manual)? That's the correct place for that type of info, IMHO.
I'll drop the SuperIO_port_guide then afterwards.
Uwe.
