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.

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().

de74f70360 [POWERPC] QE: fix invalid pointer usage in ucc_slow_init()
In two places, ucc_slow_init() passes a physical address instead of the
virtual address to functions that were expecting the latter, causing a kernel
panic.  us_info->regs contains the physical address of the UCC register set.
The registers are ioremap'd to kernel space, and the virtual pointers are
stored in us_regs.  The code was using us_info->regs when it should have been
using us_regs.

7d776cb596 [POWERPC] QE: automatically select QE options
Change the Kconfig files so that the Freescale QE options are automatically
selected if a QE device is selected.  Previously, you'd need to manually
select UCC_FAST if you want any "fast" UCC devices, such as Gigabit Ethernet.
Now, the QE Gigabit Ethernet option is always available if the device has a
QE, and UCC_FAST is automatically enabled.  A side-effect is that the
"QE Options" menu no longer exists.

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).

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.

2c1d2f34a0 [POWERPC] qe_ic: Do a sync when masking interrupts
This patch causes a sync do be done after masking a QE interrupt, to
ensure that the masking has completed before interrupts are enabled.
This allows the masking of the cascade IRQ to be removed without causing
spurious interrupts.

The mask_and_ack function is also removed and set to the mask function,
as the two are identical.

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)
