By default the iop3xx configurations are set to boot the platforms over
an nfs root configuration. Since commit c34002c1 "iop: unconditionally
initialize the ATU on platforms known to be 'hosts'" this configuration
also requires iop3xx_init_atu=y to be specified on the kernel command
line.

Currently, highmem is selectable, and you can request an increased
vmalloc area. However, none of this has any effect on the memory
layout since a patch in the highmem series was accidentally dropped.
Moreover, even if you did want highmem, all memory would still be
registered as lowmem, possibly resulting in overflow of the available
virtual mapping space.
The highmem boundary is determined by the highest allowed beginning
of the vmalloc area, which depends on its configurable minimum size
(see commit 60296c71f6 for details on
this).
We should create mappings and initialize bootmem only for low memory,
while the zone allocator must still be told about highmem.
Currently, memory nodes which are completely located in high memory
are not supported. This is not a huge limitation since systems
relying on highmem support are unlikely to have discontiguous memory
with large holes.
[ A similar patch was meant to be merged before commit 5f0fbf9eca
and be available in Linux v2.6.30, however some git rebase screw-up
of mine dropped the first commit of the series, and that goofage
escaped testing somehow as well. -- Nico ]

2.6.31-rc kernels don't boot on my ixp4xx box (ds101), because the libata
driver doesn't find the PCI IDE controller any more. 2.6.30 was fine.
I traced this to a PCI update (1f82de10d6)
in 2.6.30-git19. Diffing the kernel boot logs from 2.6.30-git18 and
2.6.30-git19 illustrates the breakage:

Every arch except arm's ixp4xx defines IO_SPACE_LIMIT as an all-bits-one
bitmask, typically -1UL but sometimes only a 16-bit 0x0000ffff. But ixp4xx
defines it as 0xffff0000, which is now causing the PCI failures.
Russell King noted that ixp4xx has 64KB PCI IO space, so IO_SPACE_LIMIT
should be 0x0000ffff. This patch makes that change, which fixes the PCI
failures on my ixp4xx box.

- Register NOP in OMAP3EVM board file using

- Select NOP_USB_XCEIV for OMAP3EVM boards.
