Malta uses this chip. The native driver does provide significant gain in
performance. See attached bonnie++ test results.
Two separate patches for both linux_2_4 branch and trunk.

CONFIG_MIPS is defined for both 32-bit and 64-bit kernel.

Algor p6032 board use it too. We have been using native driver for a
long time.

It's actually weird there are any CPU conditionals there at all. The
PIIX4 is a generic PCI-ISA bridge after all, so it can be used on any
system equipped with a PCI bus. DEC Alpha systems used to use Intel's
bridges for EISA and ISA busses as well.

I bet it's historical reasons and the whole architecture conditional
plain should go away ...

The explicit support for the PIIX family is relatively new, IIRC. I
suppose it's rather the "it's an Intel, so obviously it works with an
Intel only" thinking. I'm for the removal as well.
