The driver should pass a device that specifies internal DMA ops, but
currently NULL pointer is passed, therefore following bug appears
during boot up:

This patch adds support for multi-chip NAND devices to the FSL-UPM
driver. This requires support for multiple GPIOs for the RNB pins.
The NAND chips are selected through address lines defined by the

CoreInt provides a mechansim to deliver the IRQ vector directly
into the core on an interrupt (via the SPR EPR) rather than having
to go IACK on the PIC. This is suppose to provide an improvment
in interrupt latency by reducing the time to get the IRQ vector.

This patch tweaks the way some PTE bit combinations are defined, in such a
way that the 32 and 64-bit variant become almost identical and that will
make it easier to bring in a new common pte-* file for the new variant
of the Book3-E support.
The combination of bits defining access to kernel pages are now clearly
separated from the combination used by userspace and the core VM. The
resulting generated code should remain identical unless I made a mistake.
Note: While at it, I removed a non-sensical statement related to CONFIG_KGDB
in ppc_mmu_32.c which could cause kernel mappings to be user accessible when
that option is enabled. Probably something that bitrot.

The interrupt pending register is write 1 clear. If there are more than
one external interrupts pending at the same time, acking the first
interrupt by reading pending register then OR the corresponding bit and
write back to pending register will also clear other interrupt pending
bits. That will cause loss of interrupt.

The PCI 2.x cells used on some 44x SoCs only let us configure the decode
for the low 32-bit of the incoming PLB addresses. The top 4 bits (this
is a 36-bit bus) are hard wired to different values depending on the
specific SoC in use. Our code used to work "by accident" until I added
support for the ISA memory holes and while at it added more validity
checking of the addresses.
This patch should bring it back to working condition. It still relies
on the device-tree being correct but that's somewhat a pre-requisite
for anything to work anyway.

This patch adds support for PCI-Express controllers as found on the
newer MPC83xx chips.
The work is loosely based on the Tony Li's patch[1], but unlike the
original patch, this patch implements sliding window for the Type 1
transactions using outbound window translations, so we don't have to
ioremap the whole PCI-E configuration space.

This will avoid reoccuring spurious warnings in core kernel code that

Provides a small speedup when accessing pefetchable ranges. To indicate
that a memory range is prefetchable, mark it in the dts file with 42000000
instead of 02000000.
A powepc pci_controller is allowed three memory ranges, any of which may be
prefetchable. However, the PCI-PCI bridge configuration space only has one
field for "non-prefetchable memory behind bridge", which has a 32 bit
address, and one field for "prefetchable memory behind bridge", which may
have a 64 bit address. These are PCI bus addresses, not CPU physical
addresses.
So really you're only allowed one memory range of each type. And if you
want the range at a PCI address above 32 bits you must make it
prefetchable.

The code that sets up the outbound ATMU windows, which is used to map CPU
physical addresses into PCI bus addresses where BARs will be mapped, didn't
work so well.
For one, it leaked the ioremap() of the ATMU registers. Another small bug
was the high 20 bits of the PCI bus address were left as zero. It's legal
for prefetchable memory regions to be above 32 bits, so the high 20 bits
might not be zero.
Mainly, it couldn't handle ranges that were not a power of two in size or
were not naturally aligned. The ATMU windows have these requirements (size
& alignment), but the code didn't bother to check if the ranges it was
programming met them. If they didn't, the windows would silently be
programmed incorrectly.
This new code can handle ranges which are not power of two sized nor
naturally aligned. It simply splits the ranges into multiple valid ATMU
windows. As there are only four windows, pooly aligned or sized ranges
(which didn't even work before) may run out of windows. In this case an
error is printed and an effort is made to disable the unmapped resources.
An improvement that could be made would be to make use of the default
outbound window. Iff hose->pci_mem_offset is zero, then it's possible that
some or all of the ranges might not need an outbound window and could just
use the default window.
The default ATMU window can support a pci_mem_offset less than zero too,
but pci_mem_offset is unsigned. One could say the abilities allowed a
powerpc pci_controller is neither subset nor a superset of the abilities of
a Freescale PCIe controller. Thankfully, the most useful bits are in the
intersection of the two abilities.

The driver supports very simple GPIO controllers, that is, when a
controller provides just a 'data' register. Such controllers may be
found in various BCSRs (Board's FPGAs used to control board's
switches, LEDs, chip-selects, Ethernet/USB PHY power, etc).
So far we support only 1-byte GPIO banks. Support for other widths may
be implemented when/if needed.
p.s.
To avoid "made up" compatible entries (like compatible = "simple-gpio"),
boards must call simple_gpiochip_init() to pass the compatible string.

With this API we're able to set a QE pin to the GPIO mode or a dedicated
peripheral function.
The API relies on the fact that QE gpio controllers are registered. If
they aren't, the API won't work (gracefully though).
There is one caveat though: if anybody occupied the node->data before us,
or overwrote it, then bad things will happen. Luckily this is all in the
platform code that we fully control, so this should never happen.
I could implement more checks (for example we could create a list of
successfully registered QE controllers, and compare the node->data in the
qe_pin_request()), but this is unneeded if nobody is going to do silly
things behind our back.

The buffer descriptors for the ATA BestComm task are larger than the
current definition for bcom_bd. This causes problems because the
various bcom_... functions dereference the buffer descriptor pointer
by using the array operator which doesn't work when the buffer
descriptors are a different size.
This patch adds the bcom_get_bd() function which uses the value in
bcom_task.bd_size to calculate the offset into the BD table. This
patch also changes the definition of bcom_bd to specify a data size
of 0 instead of 1 so that it will never work if anyone attempts to
dereference the bd list as an array (as opposed to something that
might work even though it is wrong).
Finally, this patch moves the definition of bcom_bd up in the file
to eliminate a forward declaration.
