kirkwood: missing pci support for openrd_base board

[Dieter Kiermaier]

Hi all,

I try most recent kernel form kernel.org:

Linux DB88FXX81 2.6.32-rc3-00052-g0eca52a #5 PREEMPT Thu Oct 8 13:20:27 CEST 2009 armv5tel GNU/Linux

So everything else seems to work well but I can't get pci bus working?
Is PCI expected to work or are there some patches missing (and if so, where are they available?)

Many thanks for your answer!

Dieter

It's just because PCIe initialization isn't called. I sent this patch
over a month ago, but it hasn't been merged yet:

Many thanks for the patch - I've googled a lot but can't find the information.
Sorry for the noise!

Could you verify this still applies and works fine on the latest kernel 
and resend please?  Also don't forget to CC me or chances for me to miss 
the patch are greater.

[PATCH v2] OpenRD base: Initialize PCI express and i2c

[Simon Kagstrom]

Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
---
Right now I don't have a PCI card to test with, so Dieter: could you
test the patch and ack it?

ChangeLog:

v2:
  * Rebase against 2.6.32
  * Remove UART1 initialization (UART1 is not always present - either
    the SD card or UART1 is selected)

[PATCH v2] OpenRD base: Initialize PCI express and i2c

[Dieter Kiermaier]

Hi Simon,

I've tested you patch against 2.6.32-rc3 from Linus' tree and it works fine and applies without any issues.

Without patch:
h-3.2# uname -a
Linux DB88FXX81 2.6.32-rc3-00256-g36a0790 #1 PREEMPT Fri Oct 9 08:44:33 CEST 2009 armv5tel GNU/Linux
sh-3.2#
sh-3.2#
sh-3.2# lspci
sh-3.2#

with applied patch:

sh-3.2# uname -a
Linux DB88FXX81 2.6.32-rc3-00256-g36a0790-dirty #2 PREEMPT Fri Oct 9 08:47:02 CEST 2009 armv5tel GNU/Linux
sh-3.2# lspci
00:00.0 Class 0580: Device 11ab:6281 (rev 02)
00:01.0 Class 0200: Device 10ec:8168 (rev 01)
sh-3.2#

Sorry for the silly question, but what have I do to ack it?

Greetings,
Dieter

I've applied it to the orion repo.

You basically say so like you did above.  Some maintainers also prefer 
you provide a ready to cop and paste line such as:
