With my patches, this is now all omap1 specific and
moved to arch/arm/mach-omap1/include/mach/hardware.h.
It's probably easiest to just update this patch on
top of the hardware.h changes I've done.

Yes, sounds good. Do you want to send a patch for that
and let me drop this one then?

Yes I can pick this one and update it against one of my
branches to avoid merge conflicts.

This applies against mach-omap1/include/mach/hardware.h
with some fuzz so no issues there.

But I think we should not apply it as these are physical
addresses, not virtual addresses for omap1.

We have IOMEM already in use for omap_read/write because of:

#define OMAP1_IO_ADDRESS(pa)	IOMEM((pa) - OMAP1_IO_OFFSET)

I think the right solution is to eventually get rid of
omap_read/write for omap1 also and replace them with ioremap
+ readl/writel.

Or am I missing something?
