fac150e83f powerpc/lib: fix unsafe register handling in wait_ticks
If watchdog is enabled, the arch/powerpc/lib/ticks.S::wait_ticks() function
calls the function specified by the WATCHDOG_RESET macro.
The wait_ticks function depends on the registers r0, r6 and r7 being
preserved however that is not guaranteed, e.g. if the reset function is a
C function this will probably overwrite r0 and cause an endless loop.

The following patch changes to using r14+r15 instead of r6+r7 (to resemble
what would have been generated by a C compiler) and saves all necessary
registers on the stack.

The patch has been tested on a custom MPC5125 based machine using the 512x
powerpc architecture.

472d546054 Consolidate bool type
'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.

All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.

Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.

d53e340edf armv7: do not relocate _start twice
The _start symbol is already relocated, so do not add the relocation the second

de63ac278c ARM: mmu: Set domain permissions to client access
The 'XN' execute never bit is set in the pagetables. This will
 prevent speculative prefetches to non executable regions. But the
 domain permissions are set as master in the DACR register.
 So the pagetable attribute for 'XN' is not effective. Change the
 permissions to client.

 This fixes lot of speculative prefetch aborts seen on OMAP5
 secure devices.

9a4fbe4fbd mmc: add bcm2835 driver
This adds a simple driver for the BCM2835's SD controller.

Workarounds are implemented for:
* Register writes can't be too close to each-other in time, or they will
  be lost.
* Register accesses must all be 32-bit, so implement custom accessors.

This code was extracted from:
git://github.com/gonzoua/u-boot-pi.git master
which was created by Oleksandr Tymoshenko.

Portions of the code there were obviously based on the Linux kernel at:
git://github.com/raspberrypi/linux.git rpi-3.6.y
commit f5b930b "Main bcm2708 linux port" signed-off-by Dom Cobley.

swarren changed the following for upstream:
* Removed hack udelay()s in bcm2835_sdhci_raw_writel(); setting
  SDHCI_QUIRK_WAIT_SEND_CMD appears to solve the issues.
* Remove register logging from read*/write* functions.
* Sort out confusion with min/max_freq values passed to add_sdhci().
* Use more descriptive variable names and calculations in IO accessors.
* Simplified and commented twoticks_delay calculation.
* checkpatch fixes.

88077280c4 ARM: bcm2835: add mailbox driver
The BCM2835 SoC contains (at least) two CPUs; the VideoCore (a/k/a "GPU")
and the ARM CPU. The ARM CPU is often thought of as the main CPU.
However, the VideoCore actually controls the initial SoC boot, and hides
much of the hardware behind a protocol. This protocol is transported
using the SoC's mailbox hardware module.

Here, we add a very simplistic driver for the mailbox module, and define
a few structures for the property messages.
