udelay() in PCI/PCIe read/write callbacks cause 30ms IRQ latency on Octeon
platforms because these operations are called from PCI_OP_READ() and
PCI_OP_WRITE() under raw_spin_lock_irqsave().

64 bit access is unaffected but for 32 bit access, swap high and

four possible words, and for 8 bit access reverse the order of byte

Some hardware blocks attached to the OCTEON bootbus run asynchronously
to accesses from the CPUs. These include MMC/SD host, CF(when using
DMA), and NAND controller. A bus error, or corrupt data may occur if
a CPU is trying to access a bootbus connected device at the same time
the bus is running asynchronous operations.
To work around these problems we add this semaphore that must be
acquired before initiating bootbus activity. Subsequent patches will
add users for this.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS:
- a number of fixes that didn't make the 3.19 release.
- a number of cleanups.
- preliminary support for Cavium's Octeon 3 SOCs which feature up to
48 MIPS64 R3 cores with FPU and hardware virtualization.
- support for MIPS R6 processors.
Revision 6 of the MIPS architecture is a major revision of the MIPS
architecture which does away with many of original sins of the
architecture such as branch delay slots. This and other changes in
R6 require major changes throughout the entire MIPS core
architecture code and make up for the lion share of this pull
request.
- finally some preparatory work for eXtendend Physical Address
support, which allows support of up to 40 bit of physical address
space on 32 bit processors"
[ Ahh, MIPS can't leave the PAE brain damage alone. It's like
every CPU architect has to make that mistake, but pee in the snow
by changing the TLA. But whether it's called PAE, LPAE or XPA,
it's horrid crud - Linus ]

In the microMIPS encoding some memory access instructions have their
immediate offset reduced to 12 bits only. That does not match the GCC
`R' constraint we use in some places to satisfy the requirement,
resulting in build failures like this:
{standard input}: Assembler messages:
{standard input}:720: Error: macro used $at after ".set noat"
{standard input}:720: Warning: macro instruction expanded into multiple instructions
Fix the problem by defining a macro, `GCC_OFF12_ASM', that expands to
the right constraint depending on whether microMIPS or standard MIPS
code is produced. Also apply the fix to where `m' is used as in the
worst case this change does nothing, e.g. where the pointer was already
in a register such as a function argument and no further offset was
requested, and in the best case it avoids an extraneous sequence of up
to two instructions to load the high 20 bits of the address in the LL/SC
loop. This reduces the risk of lock contention that is the higher the
more instructions there are in the critical section between LL and SC.
Strictly speaking we could just bulk-replace `R' with `ZC' as the latter
constraint adjusts automatically depending on the ISA selected.
However it was only introduced with GCC 4.9 and we keep supporing older
compilers for the standard MIPS configuration, hence the slightly more
complicated approach I chose.
The choice of a zero-argument function-like rather than an object-like
macro was made so that it does not look like a function call taking the
C expression used for the constraint as an argument. This is so as not
to confuse the reader or formatting checkers like `checkpatch.pl' and
follows previous practice.

There are three parts to this:
1) Remove the definitions of OCTEON_IRQ_TWSI and OCTEON_IRQ_TWSI2.
The interrupts are specified by the device tree and these hard
coded irq numbers block the used of the irq lines by the irq_domain
code.
2) Remove platform device setup code from octeon-platform.c, it is
now unused.
3) Convert i2c-octeon.c to use device tree. Part of this includes
using the devm_* functions instead of the raw counterparts, thus
simplifying error handling. No functionality is changed.
