v2[PATCH] Initial support for the Thomson IP1000

[Joseph Smith]

Hello,
Here is a patch to add initial support for the Thomson IP1000. It is a
cousin to the RCA RM4100. More info on it can be found here:
http://www.settoplinux.org/index.php?title=Thomson_IP1000

Also attached is a coreboot bootlog with full debugging.

One question: Are you seeing an error message similar to this one when
booting Linux?

PCI: Unable to handle 64-bit address space for bridge 0000:00:1c.0
PCI: Unable to handle 64-bit address space for bridge 0000:00:1c.4
PCI: Unable to handle 64-bit address space for bridge 0000:00:1c.5
PCI: Unable to handle 64-bit address space for bridge 0000:00:1e.0

I seem to get this on all recent 32bit systems I have touched when
booting with coreboot, but I could not figure out what it is, yet.

Where are you seeing this? From the Linux kernel? It doesn't look familiar
to me. I'm not getting that on the RM4100 or IP1000. Does the board have
64-bit PCI slots?

Yes, during Linux' PCI setup, when it encounters pci-to-pci or pcie bridges.

Hmm, not sure. I'm not getting that on the RM4100 or IP1000, booting FC7,
kernel 2.6.23.15-80.fc7.
Attached is a dmesg from the coreboot/IP1000.

Looks scary, but probably harmless as you don't have ACPI.

This doesn't look too good(?) 

Not sure why this happens. You do disable floppy in Config.lb
via "device pnp 2e.0 off" (but maybe the stuff between that line
and the corresponding "end" has to be dropped? Not sure...

Can you post 'superiotool -dV' from BIOS and coreboot for comparison?

Also, your PIRQ table is the same as for RCA RM4100, is that really
the case? I.e. have you compared the getpir output of both?

Yes I think this is just because there is no ACPI. What is mutex anyways?

Yeh this started when I updated the kernel there is no floppy and it is
disabled so not sure either... maybe a gpio setting?

Sure, will do.

It should be the same except as Corey said there is a PCI slot that needs to
be added. Linux was never able to run on this box until now, so I don't
really have any way to run getpir with the original bios.

Not sure about that one either.

Very nice! So for this box coreboot is not only an alternative to a
vendor BIOS, it's the _only_ way to run Linux? Make sure to mention
this in the wiki page.

Yes, the guys Set-Top-Linux are very excited about this! It originally comes
with a proprietary bios that only boots a windows CE image (nk.bin). So yes,
this is milestone for this box.
