5af68af5bc [POWERPC] QE: clean up ucc_slow.c and ucc_fast.c
Refactored and cleaned up ucc_fast.c and ucc_slow.c so that the two files
look more alike and are easier to read.  Removed uccf_printk() and related
functions, because they were just front-ends to printk().  Fixed some
spacing and tabbing issues.  Minor optimizations of some code.  Changed
the type of some variables to their proper type (mostly buffer
descriptors).

29cfe6f4fb [POWERPC] add of_get_mac_address and update fsl_soc.c to use it
Add function of_get_mac_address(), which obtains the best MAC address to use
from the device tree by checking various properties in order.  The order is:
'mac-address', then 'local-mac-address', then 'address'.  It skips properties
that contain invalid MAC addresses, which were probably not initialized
by U-Boot.

Update gfar_of_init() and fs_enet_of_init() in fsl_soc.c to call
of_get_mac_address().

This patch changes the MPIC IPIs to be per-CPU to avoid getting a

0e8266437c [POWERPC] Add PMI driver for cell blade
This adds driver code for the PMI device found in future IBM products.
PMI stands for "Platform Management Interrupt" and is a way to
communicate with the BMC (Baseboard Management Controller).
It provides bidirectional communication with a low latency.

8f34f6cfa2 [POWERPC] QE: Rename ucc_slow_info.us_regs to ucc_slow_info.regs
Rename the 'us_regs' field of the ucc_slow_info structure in ucc_slow.h
to just 'regs'.  The equivalent field in the ucc_fast_info structure is
also called 'regs', so this patch makes them comparable, and makes the
code a little easier to read, because there already is a 'us_regs' in
another ucc_slow structure.

a1fdf6940a [POWERPC] Assign all PCI busses on G3 Blue & White
G3 Blue & White is misconfigured by default so that CardBus controllers
in PCI slots don't work.  The PCI bridge is programmed to only allow
access to bus 1 but not higher busses.

The patch forces the PCI busses to be reassigned if a Grackle controller
is found and the machine identifies itself as "PowerMac1,1"

73844ecbaa [POWERPC] cpm2: CPM2 interrupt controller fix
This contains important fixes for the CPM2 PIC code. Eliminated
CPM_IRQ_OFFSET, pulling the respective interrupt numbers from the interrupt
mapping. Updated devicetree files to reflect that. Changed direct
IC-related IO accesses to the IO accessors. Fixed all the sense values to
keep coherency with ipic. In the current code, CPM2 stuff will have no IRQs
and hence could be hardly usable.

7df2457db8 [POWERPC] MPIC: support more than 256 sources
Allow more than the default 256 MPIC sources. Allocates a new flag
(MPIC_LARGE_VECTORS) to be used by platform code when instantiating

I picked 11 bits worth right now since it would cover the number of
sources on any hardware I have seen. It can always be increased later
if needed.

126186a055 [POWERPC] 83xx: Return a point to the struct ipic from ipic_init()
It's useful to have access to struct ipic handle that just got created
in ipic_init().

For example, if we want to setup an external IRQ with out
a device node we need access ipic->irqhost to create the virtual to HW
IRQ mapping and to set the IRQ sense.  With this we can mimic the old
sense array concept that existed in arch/ppc.

The mmio nvram driver (used by cell only atm) isn't properly parsing
the device-tree, meaning that nvram isn't found correctly on the new
Cell blades.  It works ok for old blades where the nvram is at the
root of the device tree but fails on Malta and CAB when it's hanging
off axon.  This fixes it by using the proper OF parsing functions.

On 85xx we don't build in dcr support because the core doesn't implement the
