The ULI "Super South Bridge" contains ISA bridge to the legacy
devices, such as Super IO mouse/keyboard/floppy disk controllers,
parallel port, i8259 interrupt controller and so on.

On the MPC8610HPCD, i8259 seems to be disabled (mpc8610_hpcd.c
confirms this), and other peripherals are not traced out.
So we use only RTC.

This patch also adds ULI quirk to make RTC actually work (this
quirk differs a bit from the one in the fsl_uli1575.c).

Can we just one quick for both?

Probably yes, but fsl_uli1575 needs some other changes for this.

This series fully tested on MPC8610HPCD, and build-tested for
MPC85xxDS and MPC8641HPCN.

[PATCH 1/3] [POWERPC] implement machine specific PCI fixup calls

From: Anton Vorontsov <hidden>
Date: 2008-05-08 14:20:47

These are similar to machine_initcalls, but works for the PCI fixups.
We need this to apply machine specific fixups for the same PCI devices.

[PATCH 2/3] [POWERPC] turn fsl_uli1575 into PCI fixups library

From: Anton Vorontsov <hidden>
Date: 2008-05-08 14:20:50

With this patch we can choose which ULI fixups we want to apply
for the specific boards.

There are no changes to the fixups them selfs.

[PATCH 3/3] [POWERPC] fsl_uli1575: change RTC quirk to work on MPC8610HPCD

From: Anton Vorontsov <hidden>
Date: 2008-05-08 14:20:54

Currently fsl_uli1575.c's RTC quirk reads at ->start, but I got the RTC
working on the MPC8610HPCD only when reading at 0xa0100000-0xafffffff,
i.e. memory outside of behind-the-bridge devices' assigned regions.

This patch wasn't tested on the MPC85xxDS and MPC8641HPCN boards, I
don't have any of these.

The ULI "Super South Bridge" contains ISA bridge to the legacy
devices, such as Super IO mouse/keyboard/floppy disk controllers,
parallel port, i8259 interrupt controller and so on.

On the MPC8610HPCD, i8259 seems to be disabled (mpc8610_hpcd.c
confirms this), and other peripherals are not traced out.
So we use only RTC.

This patch also adds ULI quirk to make RTC actually work (this
quirk differs a bit from the one in the fsl_uli1575.c).

Can we just one quick for both?

Probably yes, but fsl_uli1575 needs some other changes for this.

This series fully tested on MPC8610HPCD, and build-tested for
MPC85xxDS and MPC8641HPCN.

Are these patches ideal? No comments so far... ;-)

Could we then apply this to the powerpc-next for proper testing?

Hi Anton,

This is not me picking on you, I just want to make a general statement.

We should not do this.  powerpc-next feeds into linux-next which is for
inter subsystem integration testing.  Architecture specific testing
should be done before things get to -next.

I am hoping that Paul will run a separate powerpc tree/branch for powerpc
wide testing and then migrate stuff form there to powerpc-next when he is
happy that things are as good as we can get.  This does not mean
"perfect". :-)

Yeah, that would be great.
