This is the IQ80332 platform port that's based off the IOP33x CPU. The IQ80332 is an PCI-express CRB based off the IOP332 processor. Otherwise functionalites are fairly similar to IQ80331.

Patch from Deepak Saxena

The IXP46x chips from Intel include the same I2C controller as found
on the IOP3xx.  This patch adds a hook to the platform-level init code
to add that device to the device tree if running on a 46x CPU. A
separate patch has been sent upstream via Greg KH for the changes to the
I2C driver to support both IOP and IXP systems.

While at it, we fix a minor issue with the code where we were sending 
the wrong ptr to platform_add_devices(). I am not sure how it ever 
worked...

Since we no longer pass a struct request to the MMC host drivers,
it seems pointless including linux/blkdev.h.  Instead, include

The regular executable loader path doesn't need the locking,
because it's the only user of its VM. But the same is not true
at library load time. So get the mmap semaphore.

From: Jim Paris <jim@jtan.com>

Bartlomiej: I have an ICH3-M controller on my laptop.  The BIOS is
leaving the prog-if as 0x8E (primary = legacy, secondary = native).
When the PCI interrupt is routed (either in the IDE driver's
pci_enable_device, or earlier if pci=routeirq is used), unhandled
interrupts cause IRQ 9 to be disabled, breaking most of my other
hardware.  This seems to be caused by having the nonexistant secondary
interface set to native mode.  According to the datasheet I checked,
having different modes for primary/secondary is not an allowed
combination anyway, so the following PCI quirk checks for this case
and forces both interfaces to legacy if true.

It may make sense to make this more generic (this problem may affect
other PCI IDs as well), or it may be better solved in the IDE driver,
at least when pci=routeirq is not used.  But the following patch does
work well for me.

Oh, bugger...

The recent mmzone.h change triggered some very, very ugly things in
next_zone(), is_highmem(), is_normal() and zone_idx() because it changed
the size of "struct zone" subtly.

Pointer subtraction is no fun when sizeof of object gets weird and poor
gcc blows its brains out trying to optimize that...  This slowed down an
ARM cross-build by a factor of 2.5. 

Turn the pointer subtraction tests into pointer addition tests instead
where possible, making them trivial to deal with (and gets better code,
in addition to faster compile).

zone_idx() still does a subtraction.
