bca7ab316e ARM: mmp: register internal sram bank
MMP2 have the internal sram, this sram can be allocated
for video, power management and secure processor.

Now the sram usage is:
0xd1000000 ~ 0xd101ffff (128KB) : reserved for secure processor
0xd1020000 ~ 0xd1037fff (96KB)  : for video and PM

Register the internal sram's second half 96KB buffer,
so that video and PM can dynamically alloc/free from it.

3c7241bd36 ARM: mmp: add sram allocator
On mmp platform, there have two sram banks:
audio sram and internal sram. The audio sram is mainly for audio;
the internal sram is for video, wtm and power management.
So add the sram allocator using genalloc to manage them.

Every sram bank will register its own platform device
info, after the sram allocator create the generic pool
for the sram bank, the user module can use the pool's
name to get the pool handler; then it can use the handler
to alloc/free memory with genalloc APIs.

This first basic support will be populated as drivers and boards will be

Contains serial, dma and interrupt controllers.

The generic board file still takes advantage of platform data for early serial
init. As we need a storage media and the NAND flash driver is not converted to
DT yet, we keep old initialization for it.

590842f909 ARM: i.MX28: shift frac value in _CLK_SET_RATE
Noticed when setting SSP0 in clk_set_rate, _CLK_SET_RATE attempts to
reset the clock divider for the SSP0 parent clock, in this case
IO0FRAC. Bits 24-29 of HW_CLKCTRL_FRAC0 are cleared correctly, but
when the new frac value is written the value isn't shifted up to write
the correct bit-field.  This results in IO0FRAC being set to 0 and
CPUFRAC being corrupted.

This should occur when writing IO1FRAC, EMIFRAC in HW_CLKCTRL_FRAC0
and GPMIFRAC, HSADCFRAC in HW_CLKCTRL_FRAC1.

Tested on custom i.MX28 board with SSP0 SPI driver.

6571534b60 plat-mxc: iomux-v3.h: implicitly enable pull-up/down when that's desired
To configure pads during the initialisation a set of special constants
is used, e.g.
#define MX25_PAD_FEC_MDIO__FEC_MDIO IOMUX_PAD(0x3c4, 0x1cc, 0x10, 0, 0, PAD_CTL_HYS | PAD_CTL_PUS_22K_UP)

The problem is that no pull-up/down is getting activated unless both
PAD_CTL_PUE (pull-up enable) and PAD_CTL_PKE (pull/keeper module
enable) set. This is clearly stated in the i.MX25 datasheet and is
confirmed by the measurements on hardware. This leads to some rather
hard to understand bugs such as misdetecting an absent ethernet PHY (a
real bug i had), unstable data transfer etc. This might affect mx25,
mx35, mx50, mx51 and mx53 SoCs.

It's reasonable to expect that if the pullup value is specified, the
intention was to have it actually active, so we implicitly add the
needed bits.

8a0a8e8e42 mfd: remove CONFIG_MFD_SUPPORT
We currently have two symbols to control compilation the MFD subsystem,
MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required
at all, it only hides the submenu when not set, with the effect that
Kconfig warns about missing dependencies when another driver selects
an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu
back from menuconfig into a plain menu simplifies the Kconfig syntax
for those kinds of users and avoids the surprise when the menu
suddenly appears because another driver was enabled that selects this
symbol.

eb0474544b ARM: 7133/1: SMP: fix per cpu timer setup before the cpu is marked online
The problem is related to the early enabling of interrupts and the
per cpu timer setup before the cpu is marked online. This doesn't
need to be done in order to call calibrate_delay().

calibrate_delay() monitors jiffies, which are updated from the CPU
which is waiting for the new CPU to set the online bit.

So simply calibrate_delay() can be called on the new CPU just from
the interrupt disabled region and move the local timer setup after
stored the cpu data and before enabling interrupts.

This solves both the cpu_online vs. cpu_active problem and the
affinity setting of the per cpu timers.

This patch remove the hardcoded link between local timers and PPIs,
and convert the PPI users (TWD, MCT and MSM timers) to the new
*_percpu_irq interface. Also some collateral cleanup
(local_timer_ack() is gone, and the interrupt handler is strictly
private to each driver).

PPIs are now useable for more than just the local timers.

292b293cee ARM: gic: consolidate PPI handling
PPI handling is a bit of an odd beast. It uses its own low level
handling code and is hardwired to the local timers (hence lacking
a registration interface).

Instead, switch the low handling to the normal SPI handling code.
PPIs are handled by the handle_percpu_devid_irq flow.

This also allows the removal of some duplicated code.

6c5482d53f ARM: 7129/1: Add __arm_ioremap_exec for mapping external memory as MT_MEMORY
This allows mapping external memory such as SRAM for use.

This is needed for some small chunks of code, such as reprogramming
SDRAM memory source clocks that can't be executed in SDRAM. Other
use cases include some PM related code.

ee3f615819 ARM: 7136/1: pl330: Fix a race condition
If two requests have been submitted and one of them is running, if you
call pl330_chan_ctrl(ch_id, PL330_OP_START), there's a window of time
between the spin_lock_irqsave() and the _state() check in which the
running transaction may finish.  In that case, we don't receive the
interrupt (because they are disabled), but _start() sees that the DMA
is stopped, so it starts it.  The problem is that it sends the
transaction that has just finished again, because pl330_update()
hasn't mark it as done yet.

This patch fixes this race condition by not calling _start() if the
DMA is already executing transactions.  When interrupts are reenabled,
pl330_update() will call _start().

382414b93a ARM: mach-shmobile: sh7372 A4R support (v4)
This change adds support for the sh7372 A4R power domain.

The sh7372 A4R hardware power domain contains the
SH CPU Core and a set of I/O devices including
multimedia accelerators and I2C controllers.

One special case about A4R is the INTCS interrupt
controller that needs to be saved and restored to
keep working as expected. Also the LCDC hardware
blocks are in a different hardware power domain
but have their IRQs routed only through INTCS. So
as long as LCDCs are active we cannot power down
INTCS because that would risk losing interrupts.

d93f5cdea9 ARM: mach-shmobile: sh7372 A3SP support (v4)
This change adds support for the sh7372 A3SP power domain.

The sh7372 A3SP hardware power domain contains a
wide range of I/O devices. The list of I/O devices
include SCIF serial ports, DMA Engine hardware,
SD and MMC controller hardware, USB controllers
and I2C master controllers.

This patch adds the A3SP low level code which
powers the hardware power domain on and off. It
also ties in platform devices to the pm domain
support code.

It is worth noting that the serial console is
hooked up to SCIFA0 on most sh7372 boards, and
the SCIFA0 port is included in the A3SP hardware
power domain. For this reason we cannot output
debug messages from the low level power control
code in the case of A3SP.

QoS support is needed in drivers before we can
enable the A3SP power control on the fly.

fb630b9fc9 ARM: S3C24XX: Fix s3c24xx build errors if !CONFIG_PM
v2:
- register_syscore_ops(&s3c24xx_irq_syscore_ops) does not need to be
  conditionally compiled out, it is already optimized out on !CONFIG_PM
- fix also s3c2412 and s3c2416 affected by the same build issue

v1:
s3c2440.c fails to build if !CONFIG_PM because in such case
s3c2410_pm_syscore_ops is not defined. Same error should happen also
in s3c2410.c and s3c2442.c

b55fa18817 ARM: 7137/1: Fix error upon adding LL debug
Upon adding new board LL debug support, if the resultant code
addition would not cause PC relative offset of "hexbuf" from
"adr r2, hexbuf" (+2) instruction to be representable in a
shifted 8-bit value (hence indirectly putting higher aligment
requirement on larger offsets), following error occurs,

arch/arm/kernel/debug.S: Assembler messages:
arch/arm/kernel/debug.S:138: Error: invalid constant (428) after fixup

Fix it by bringing "hexbuf" closer so that "adr"
can have the offset.
