Hi !
The powerpc.git next branch has now been updated with the following
patches. The "test" branch has been reset.

powerpc/pseries: Return the number of MSIs we could allocate
If we can't allocate the requested number of MSIs, we can still tell the
generic code how many we were able to allocate. That can then be passed
onto the driver, allowing it to request that many in future, and
probably succeeed.

The lmb debugging can be turned on at boottime with lmb=debug on the

So always call lmb_dump_all() after lmb_analyze(), no output is

powerpc/5200: Rework GPT driver to also be an IRQ controller
This patch adds IRQ controller support to the MPC5200 General
Purpose Timer (GPT) device driver. With this patch the mpc5200-gpt
driver supports both GPIO and IRQ functions.
The GPT driver was contained within the mpc52xx_gpio.c file, but this
patch moves it out into a new file (mpc52xx_gpt.c) since it has more
than just GPIO functionality now and it was only grouped with the
mpc52xx-gpio drivers as a matter of convenience before. Also, this
driver will most likely get extended again to also provide support
for the timer function.
Implementation note: Alternately, I could have tried to implement
the IRQ support as a separate driver and left the GPIO portion alone.
However, multiple functions of this device (ie. GPIO input+interrupt
controller, or timer+GPIO) can be active at the same time and the
registers are shared so it is safer to contain all functionality
within a single driver.

Rework the mpc5200-pic driver to simplify it and fix up the setting
of desc->status when set_type is called for internal IRQs (so they
are reported as level, not edge). The simplification is due to
splitting off the handling of external IRQs into a separate block
so they don't need to be handled as exceptions in the normal
CRIT, MAIN and PERP paths.

- removal of cell-index properties
- Addition of gpio-controller and #gpio-cells properties to gpio
nodes
- Move common interrupt-parent property out of device nodes and
into top level parent node.
This patch also include what looks to be just trivial editorial
whitespace/format changes, but there is real method in this
madness. Editorial changes were made to keep the all the
mpc5200 board device trees as similar as possible so that diffs
between them only show the real differences between the boards.
The pcm030 device tree was most affected by this because many
of the comments had been changed from // to /* */ style and
some cell values where changed from decimal to hex format when
it was cloned from one of the other 5200 device trees.

powerpc/5200: Stop using device_type and port-number properties
There is no reason for the PSC UART driver or the Ethernet driver
to require a device_type property. The compatible value is sufficient
to uniquely identify the device. Remove it from the driver.
The whole 'port-number' scheme for assigning numbers to PSC uarts was
always rather half baked and just adds complexity. Remove it from the
driver. After this patch is applied, PSC UART numbers are simply
assigned from the order they are found in the device tree (just like
all the other devices). Userspace can query sysfs to determine what
ttyPSC number is assigned to each PSC instance.

powerpc/fsl-booke: Allow larger CAM sizes than 256 MB
The code that maps kernel low memory would only use page sizes up to 256
MB. On E500v2 pages up to 4 GB are supported.
However, a page must be aligned to a multiple of the page's size. I.e.
256 MB pages must aligned to a 256 MB boundary. This was enforced by a
requirement that the physical and virtual addresses of the start of lowmem
be aligned to 256 MB. Clearly requiring 1GB or 4GB alignment to allow
pages of that size isn't acceptable.
To solve this, I simply have adjust_total_lowmem() take alignment into
account when it decides what size pages to use. Give it PAGE_OFFSET =
0x7000_0000, PHYSICAL_START = 0x3000_0000, and 2GB of RAM, and it will map
pages like this:
PA 0x3000_0000 VA 0x7000_0000 Size 256 MB
PA 0x4000_0000 VA 0x8000_0000 Size 1 GB
PA 0x8000_0000 VA 0xC000_0000 Size 256 MB
PA 0x9000_0000 VA 0xD000_0000 Size 256 MB
PA 0xA000_0000 VA 0xE000_0000 Size 256 MB
Because the lowmem mapping code now takes alignment into account,
PHYSICAL_ALIGN can be lowered from 256 MB to 64 MB. Even lower might be
possible. The lowmem code will work down to 4 kB but it's possible some of
the boot code will fail before then. Poor alignment will force small pages
to be used, which combined with the limited number of TLB1 pages available,
will result in very little memory getting mapped. So alignments less than
64 MB probably aren't very useful anyway.

powerpc/fsl-booke: Remove code duplication in lowmem mapping
The code to map lowmem uses three CAM aka TLB[1] entries to cover it. The

All the code that uses them is duplicated three times for each of the three
variables.
We have these things called arrays and loops....

powerpc/fsl-booke: Cleanup init/exception setup to be runtime
We currently have a few variants of fsl-booke processors (e500v1, e500v2,
e500mc, and e200). They all have minor differences that we had previously
been handling via ifdefs.
To move towards having this support the following changes have been made:
* PID1, PID2 only exist on e500v1 & e500v2 and should not be accessed on
e500mc or e200. We use MMUCFG[NPIDS] to determine which case we are
since we only touch PID1/2 in extremely early init code.
* Not all IVORs exist on all the processors so introduce cpu_setup
functions for each variant to setup the proper IVORs that are either
unique or exist but have some variations between the processors

powerpc/fsl_pci: Add MPC83xx PCI-E controller RC mode support
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.
