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)

The problem was caused because MSI irq was not being effectively

This patch fixes two issues in the procfs stack information on
x86-64 linux.
The 32 bit loader compat_do_execve did not store stack
start. (this was figured out by Alexey Dobriyan).
The stack information on a x64_64 kernel always shows 0 kbyte
stack usage, because of a missing implementation of the KSTK_ESP
macro which always returned -1.
The new implementation now returns the right value.

Building with --build-id option, .note.gnu.build-id section is added
to vmlinux.bin. But some old buggy binutils creates a huge vmlinux.bin,
and a bootloader fails to boot its zImage as well.
This patch adds a NOTES macro to a linker script vmlinux.ld.S to put
.note.gnu.build-id section into .note section.
Then, the .note section will be removed, because "-R .note" option is

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).

Mapping the same memory using two different attributes (memory
type, shareability, cacheability) is unpredictable. During boot,
we encounter a situation when we're updating the kernel's page
tables which can lead to dirty cache lines existing in the cache
which are subsequently missed. This causes stack corruption,
and therefore a crash.
Therefore, ensure that the shared and cacheability settings
matches the configuration that will be used later; this together
with the restriction in early_cachepolicy() ensures that we won't
create a mismatch during boot.

The handle_edge_irq() flowhandler disables edge int sources which occur
too fast (i.e. another edge comes in before the irq handler function
had a chance to finish). Currently, the mask_ack() callback does not
ack the edges in hardware, leading to an endless loop in the flowhandler
where it tries to shut up the irq source.
When I rewrote the alchemy IRQ code I wrongly assumed the mask_ack()
callback was only used by the level flowhandler, hence it omitted the
(at the time pointless) edge acks. Turned out I was wrong; so here
is a complete mask_ack implementation for Alchemy IC, which fixes
the above mentioned problem.
