Rather than forcing GFP flags and DMA mask to be inconsistent,
GFP flags should be determined even for the fallback device
through dma_alloc_coherent_mask()/dma_alloc_coherent_gfp_flags().
This restores 64-bit behavior as it was prior to commits
8965eb19386fdf5ccd0ef8b02593eb8560aa3416 and
4a367f3a9dbf2e7ffcee4702203479809236ee6e (not sure why there are
two of them), where GFP_DMA was forced on for 32-bit, but not
for 64-bit, with the slight adjustment that afaict even 32-bit
doesn't need this without CONFIG_ISA.

Fix the following BUG_ON() problem reported by Alex Chiang.
This problem happened when removing PCIe root port using PCI logical
hotplug operation.
The immediate cause of this problem is that the pointer to invalid
data structure is passed to pcie_update_aspm_capable() by
pcie_aspm_exit_link_state(). When pcie_aspm_exit_link_state() received
a pointer to root port link, it unconfigures the root port link and
frees its data structure at first. At this point, there are not links
to configure under the root port and the data structure for root port
link is already freed. So pcie_aspm_exit_link_state() must not call
pcie_update_aspm_capable() and pcie_config_aspm_path().
This patch fixes the problem by changing pcie_aspm_exit_link_state()
not to call pcie_update_aspm_capable() and pcie_config_aspm_path() if
the specified link is root port link.

This patch fixes USB GPIOs numbers for MPC8569E-MDS boards, plus
according to the latest HW Getting Started Guide (rev 3.3, pilot
boards), USB "POWER" GPIO polarity has changed, it is no longer
inverted.
This patch makes USB Host somewhat work on pilot boards, though
there are still some problems with determining devices speed and
long bulk transfers.

The PCI-e addressing was originally patterned of the MPC8548CDS
which has PCI1, PCI2, and PCI-e. Since this board only has
PCI1 and PCI-e, it makes more sense to be similar to the MPC8568MDS
board. This does that by cutting the PCI/PCI-e I/O sizes from
16MB to 8MB and pulling the PCI-e I/O range back to 0xe280_0000
(the hole where PCI2 I/O would have been).
This also fixes a typo where an extra zero made an 8MB range a 128MB
range, removes the hole left by PCI2 from the aliases, and sets the
clocks to match the oscillators that are actually on the board.
With accompanying u-boot updates, PCI-e has been validated with
both a sky2 card (1148:9e00) and an e1000 card (8086:108b).

The RealView PBX board has two 512MB blocks of memory - one at
0x70000000 (with 256MB mirror at 0) and another at 0x20000000. Only the
block at 0x70000000 (or the mirror at 0) may be used for DMA (e.g.
framebuffer). This patch adds the sparsemem definitions to allow the use
of all the memory split as follows:
256MB @ 0x00000000 (ZONE_DMA)
512MB @ 0x20000000 (ZONE_NORMAL)
256MB @ 0x80000000 (ZONE_NORMAL)

Instead of allocating PCI devices I/O port bus addresses from the
000xxxxx I/O port range as intended, due to a bus versus physical
address mixup, the Kirkwood PCIe handling code inadvertently
allocated I/O port bus addresses from the f20xxxxx address range
(which is the physical address range of the PCIe I/O mapping window),
but then direct all I/O port accesses to bus addresses 000xxxxx,
which would then not be decoded at all.
Fix this by setting the base address of the PCIe I/O space struct
resource to KIRKWOOD_PCIE_IO_BUS_BASE instead of the incorrect
KIRKWOOD_PCIE_IO_PHYS_BASE, and fix up __io() to expect addresses
offsetted by the former instead of the latter.
(The suggested fix of directing I/O port accesses from the host to
bus addresses f20xxxxx instead has the problem that assigning full
32bit I/O port bus addresses (f20xxxxx) doesn't work on all PCI
devices, as not all PCI devices implement full 32 bit BAR registers
for I/O ports. We should really try to allocate I/O port bus
addresses that fit in 16 bits.)

Borzoi, Terrier and Akita use the same NAND Flash OOB layout, which
seems to be different from Spitz for some reason. Here is a fix.
When the code was ported to the platform data, the map was applied just
for Akita.
After this patch, Flash works again on Borzoi. Terrier still has a
problem with partition table different from Borzoi (unfixable without
reading of the system configuration in flash) and JFFS2 partitions can
be mounted (with some "Empty flash at ... ends at ..." in the syslog).

Generally this is done at post, but might not always be done
with softboot or for connectors on docking stations.
Could probably be done once when the driver loads/resumes
rather than on each mode set.

The Lenovo W500 laptop hangs inside an SMI on brightness changes,
I thought it just needed the VGA disable but it turned out to require
slightly more work, setting the MC locations up just like the IGP
chip requirements seems to make it all happy again and I can boot
and play with brightness.
We should probably just do this for all chips and give up the VRAM
at 0x0 idea, it never seems to buy us anything but pain.

Once kms is enabled we don't need these, and it causes a problem
with the Lenovo W500 ACPI brightness implementation, it hangs
in a loop inside an SMI.

Immediate readback seems faulty on some chips. I
suspect it takes a while to get through the fifo
to the actual register backbone. There's no need
to read it back, so, just write the driver's copy
of the register's value directly.
Should fix bug 24535 and possibly 24218
