Normally logical and hard cpu ID are the same, however in same cases like
on the P3060 they may differ. Where the logical is 0..5, the hard id
goes 0,1,4..7. This can causes issues for places we utilize PIR to index
into array like in debug exception handlers for finding the exception
stack.
Move to setting up PIR with hard_smp_processor_id fixes the issue.

Standarize and document the FPGA nodes used on Freescale QorIQ reference
boards. There are different kinds of FPGAs used on the boards, but
only two are currently standard: "pixis", "ngpixis", and "qixis". Although
there are minor differences among the boards that have one kind of FPGA, most
of the functionality is the same, so it makes sense to create common
compatibility strings.
We also need to update the P1022DS platform file, because the compatible
string for its PIXIS node has changed. This means that older kernels are
not compatible with newer device trees. This is not a real problem, however,
since that particular function doesn't work anyway. When the DIU is active,
the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped
device.

Commit 765342526246c97600e5344c0949824d94bb51c3 made some small changes to
IPI, message_pass in smp_ops was initialized to NULL for other platforms
but not for 85xx which causes us to always use the mpic for IPI's even
if we support doorbells in HW.

There's only p2041rdb board for official release, but the p2041 silicon
on the board can be converted to p2040 silicon without XAUI and L2 cache
function, then the board becomes p2040rdb board. so we use the file name
p2041_rdb.c to handle P2040RDB board and P2041RDB board which is also
consistent with the board name under U-Boot.
During the rename we make few other minor changes to the device tree:
* Move USB phy setting into p2041si.dtsi as its SoC not board defined
* Convert PCI clock-frequency to decimal to be more readable

Move the driver to the place where it is expected to be nowadays. Also
rename its CONFIG-name to match the rest and adapt the defconfigs.
Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to

The firmware doesn't wait after lifting the PCI reset. However it does
timestamp it in the device tree. We use that to ensure we wait long

OPAL can handle various interrupt for us such as Machine Checks (it
performs all sorts of recovery tasks and passes back control to us with
informations about the error), Hardware Management Interrupts and Softpatch

This wires up the mechanisms and prints out specific informations returned

This adds a udbg and an hvc console backend for supporting a console
using the OPAL console interfaces.
On OPAL v1 we have hvc0 mapped to whatever console the system was
configured for (network or hvsi serial port) via the service
processor.
On OPAL v2 we have hvcN mapped to the Nth console provided by OPAL
which generally corresponds to:
hvc0 : network console (raw protocol)
hvc1 : serial port S1 (hvsi)
hvc2 : serial port S2 (hvsi)
Note: At this point, early debug console only works with OPAL v1
and shouldn't be enabled in a normal kernel.

On machines supporting the OPAL firmware version 1, the system
is initially booted under pHyp. We then use a special hypercall
to verify if OPAL is available and if it is, we then trigger
a "takeover" which disables pHyp and loads the OPAL runtime
firmware, giving control to the kernel in hypervisor mode.
This patch add the necessary code to detect that the OPAL takeover
capability is present when running under PowerVM (aka pHyp) and
perform said takeover to get hypervisor control of the processor.
To perform the takeover, we must first use RTAS (within Open
Firmware runtime environment) to start all processors & threads,
in order to give control to OPAL on all of them. We then call
the takeover hypercall on everybody, OPAL will re-enter the kernel
main entry point passing it a flat device-tree.

This adds a skeletton for the new Power "Non Virtualized"
platform which will be used by machines supporting running
without an hypervisor, for example in order to run KVM.
These machines will be using a new firmware called OPAL
for which the support will be provided by later patches.
The PowerNV platform is intended to be also usable under
the BML environment used internally for early CPU bringup
which is why the code also supports using RTAS instead of
OPAL in various places.

Since commit 188917e183cf9ad0374b571006d0fc6d48a7f447, /proc/ppc64 is a
symlink to /proc/powerpc/. That means that creating /proc/ppc64/eeh will
end up with a unaccessible file, that is not listed under /proc/powerpc/

Enable hugepages on Freescale BookE processors. This allows the kernel to
use huge TLB entries to map pages, which can greatly reduce the number of
TLB misses and the amount of TLB thrashing experienced by applications with
large memory footprints. Care should be taken when using this on FSL
processors, as the number of large TLB entries supported by the core is low
(16-64) on current processors.
The supported set of hugepage sizes include 4m, 16m, 64m, 256m, and 1g.
Page sizes larger than the max zone size are called "gigantic" pages and
must be allocated on the command line (and cannot be deallocated).
This is currently only fully implemented for Freescale 32-bit BookE
processors, but there is some infrastructure in the code for
64-bit BooKE.

Now that the generic code has dma_map_ops set, instead of having a
messy ifdef & if block in the base dma_get_required_mask hook push
the computation into the dma ops.
If the ops fails to set the get_required_mask hook default to the
width of dma_addr_t.
This also corrects ibmbus ibmebus_dma_supported to require a 64
bit mask. I doubt anything is checking or setting the dma mask on
that bus.

The hook dma_get_required_mask is supposed to return the mask required
by the platform to operate efficently. The generic version of
dma_get_required_mask in driver/base/platform.c returns a mask based
only on max_pfn. However, this is likely too big for iommu systems
and could be too small for platforms that require a dma offset or have
a secondary window at a high offset.
Override the default, provide a hook in ppc_md used by pseries lpar and
cell, and provide the default answer based on memblock_end_of_DRAM(),
with hooks for get_dma_offset, and provide an implementation for iommu
that looks at the defined table size. Coverting from the end address
to the required bit mask is based on the generic implementation.
The need for this was discovered when the qla2xxx driver switched to
64 bit dma then reverted to 32 bit when dma_get_required_mask said
32 bits was sufficient.

Recent versions of firmware will fail to unmap the virtual processor
area if we have a dispatch trace log registered. This causes kexec

If a trace log is registered this patch unregisters it before the

The address argument is ignored by firmware on unregister so we

Change the string to check for CAMP mode boot on MPC85xx (eg. P2020) to match
the one in the corresponding dts files (p2020rdb_camp_core{0,1}.dts).
Without this fix the mpic is configured as in the SMP boot mode, which causes
the first core to report a protected source interrupt error for devices
of the other core and lock up.
Also add MPIC_SINGLE_DEST_CPU on both P2020 based architectures in CAMP
mode as suggested by Scott Wood. Thanks.

The 64-bit Book-E parts (to date) dont utilize the 'server' class
perfmon. So building or depending on it makes no sense (and does break
FSL Book-E 64-bit support). Move the selection of PPC_HAVE_PMU_SUPPORT
to be based on PPC_BOOK3S_64.
Based on a patch from Scott Wood.
