Kim Phillips 6c4a2501d0 [POWERPC] Add initial support for the e300c2 core
Add support for the Freescale e300c2 core found in the MPC832x processor line.

As far as initial kernel support is concerned, the e300c2 core is
identical to the e300c1 found in the mpc834x, except that it's had its
floating point unit chopped off.

Li Yang 9865853851 [POWERPC] Add QUICC Engine (QE) infrastructure
Add QUICC Engine (QE) configuration, header files, and
QE management and library code that are used by QE devices
drivers.

Includes Leo's modifications up to, and including, the
platform_device to of_device adaptation:

"The series of patches add generic QE infrastructure called
qe_lib, and MPC8360EMDS board support.  Qe_lib is used by
QE device drivers such as ucc_geth driver.

This version updates QE interrupt controller to use new irq
mapping mechanism, addresses all the comments received with
last submission and includes some style fixes.

v2: Change to use device tree for BCSR and MURAM;
Remove I/O port interrupt handling code as it is not generic
enough.

v3: Address comments from Kumar;  Update definition of several
device tree nodes;  Copyright style change."

In addition, the following changes have been made:

o removed typedefs
o uint -> u32 conversions
o removed following defines:
  QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
  BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
  because they hid sizeof/in_be32/out_be32 operations from the reader.
o fixed qe_snums_init() serial num assignment to use a const array
o made CONFIG_UCC_FAST select UCC_SLOW
o reduced NR_QE_IC_INTS from 128 to 64
o remove _IO_BASE, etc. defines (not used)
o removed irrelevant comments, added others to resemble removed BD_ defines
o realigned struct definitions in headers
o various other style fixes including things like pinMask -> pin_mask
o fixed a ton of whitespace issues
o marked ioregs as __be32/__be16
o removed platform_device code and redundant get_qe_base()
o removed redundant comments
o added cpu_relax() to qe_reset
o uncasted all get_property() assignments
o eliminated unneeded casts
o eliminated immrbar_phys_to_virt (not used)

Paul Mackerras 0a730ae599 [POWERPC] Don't try to just continue if xmon has no input device
Currently, if xmon has no input device (as is generally the case on
G5 powermacs), and we drop into xmon as a result of a fatal exception,
it will return 1, which die() interprets as "continue without causing
an oops".  This fixes it by making xmon() return 0 in the case where
it has no input device.

Benjamin Herrenschmidt 2ec6ef1034 [POWERPC] Get default baud rate in udbg_scc
On powermac, when open firmware is set to use the SCC for console, this
causes the low level udbg early console to read back the speed and
re-use it instead of hard coding 57600 bps. This doesn't (yet) pass the
detected speed all the way to pmac_zilog though.

Michael Ellerman 4767928394 [POWERPC] Fix xmon=off and cleanup xmon initialisation
My patch to make the early xmon logic work with earlier early param
parsing (480f6f35a1) breaks xmon=off.

No one does this obviously as xmon rocks, but it should really work
as documented.

While fixing that it struck me that we could move the xmon param
handling into xmon.c, and also consolidate the
xmon_init()/do_early_xmon logic into xmon_setup(). This means
xmon=early drops into xmon a little earlier on 32-bit, but it
seems to work just fine.

Tested on PSERIES and CLASSIC32.

Michael Ellerman 23b8acb1cf [POWERPC] Cleanup include/asm-powerpc/xmon.h
For some reason we have two prototypes for xmon_init(), remove the
one in system.h.

No one calls xmon() anymore, debugger() is preferable, so we don't
need the prototype. And similarly no one calls xmon_printf().

Also update the include guards on xmon.h to match the standard
format, add copyright and license, and add comments to #endifs.

Built for pseries_defconfig and pmac32_defconfig.

Benjamin Herrenschmidt 2e19458312 [POWERPC] Cell interrupt rework
This patch reworks the cell iic interrupt handling so that:

 - Node ID is back in the interrupt number (only one IRQ host is created
for all nodes). This allows interrupts from sources on another node to
be routed non-locally. This will allow possibly one day to fix maxcpus=1
or 2 and still get interrupts from devices on BE 1. (A bit more fixing
is needed for that) and it will allow us to implement actual affinity
control of external interrupts.

 - Added handling of the IO exceptions interrupts (badly named, but I
re-used the name initially used by STI). Those are the interrupts
exposed by IIC_ISR and IIC_IRR, such as the IOC translation exception,
performance monitor, etc... Those get their special numbers in the IRQ
number space and are internally implemented as a cascade on unit 0xe,
class 1 of each node.
