Timur Tabi 90c615bc42 [POWERPC] QE: fix Kconfig 'select' warning with UCC_FAST
The UCC_GETH Kconfig option in drivers/net/Kconfig had a line to select the
UCC_FAST option is arch/powerpc/sysdev/qe_lib/Kconfig, which is only used
on PowerPC builds.  On other architectures, this would generated a warning.
The fix is to have UCC_FAST depend on UCC_GETH.

This patch creates platform_device entries for the Marvell mv64x60
I2C ports, based on information contained in device tree.

This driver (like the other mv64x60 drivers) are unusual in that it

the drivers do not support the normal PowerPC of_platform_bus_type.

Timur Tabi 4c35630ccd [POWERPC] Change rheap functions to use ulongs instead of pointers
The rheap allocation functions return a pointer, but the actual value is based
on how the heap was initialized, and so it can be anything, e.g. an offset
into a buffer.  A ulong is a better representation of the value returned by
the allocation functions.

This patch changes all of the relevant rheap functions to use a unsigned long
integers instead of a pointer.  In case of an error, the value returned is
a negative error code that has been cast to an unsigned long.  The caller can
use the IS_ERR_VALUE() macro to check for this.

All code which calls the rheap functions is updated accordingly.  Macros
IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE().

Also added error checking to rh_attach_region().

David Gibson 197686dfe0 [POWERPC] Abolish powerpc_flash_init()
powerpc_flash_init() implements a broken way of probing for flash
devices supported by the physmap_of driver.  It finds all nodes in the
device tree with device_type=="rom" and instantiates of_platform
devices for them.  This is fundamentally incompatible with the normal
and correct way of probing for of_platform_bus_probe().  Platforms
which relied on powerpc_flash_init()s behaviour (none are in-tree)
will have to update their platform probing code to correctly probe
busses containing flash devices.

Michael Ellerman 05af7bd2d7 [POWERPC] MPIC U3/U4 MSI backend
MPIC U3/U4 MSI backend. Based on code from Segher, heavily hacked by me.
This only deals with MSI on U3/U4 MPICs, aka. CPC 9x5.

If we find a U3/U4 then we enable this backend, ie. take over the ppc_md
MSI hooks. We might need more elaborate logic in future to decide which
backend is enabled.

We need our own irq_chip so that we can do MSI masking/unmasking on
the device itself. We also need to mask explicitly on shutdown to make
sure we don't get bitten by lazy-disable semantics.

code a little easier to read, because there already is a 'us_regs' in
another ucc_slow structure.

Pavel Roskin 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"

Vitaly Bordug 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.

Olof Johansson 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
the mpic.

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.
