c553138fbd ARM: imx: use endian-safe readl/readw/writel/writew
Instead of __raw_*, define imx_* to *_relaxed and use those.

Using imx_* was requested by Arnd because *_relaxed tends to
indicate that the code was carefully reviewed to not require
any synchronisation and otherwise be safe, which isn't the
case here with the automatic conversion.

The conversion itself was done using the following spatch
(since that automatically adjusts the coding style unlike
a simple search&replace).

50f2de6126 ARM: imx: include hardware.h rather than mach/hardware.h
It moves a bunch of header files included in hardware.h and itself
from mach-imx/include/mach to mach-imx, and updates users to include
hardware.h rather than mach/hardware.h.  The files in mach-imx/devices
will need to include "../hardware.h".

e3372474cf ARM: imx: include common.h rather than mach/common.h
Rename mach-imx/include/mach/common.h to mach-imx/common.h and update
all users to include common.h rather than mach/common.h.

It also removes an unneeded inclusion to common.h in
mach-imx/devices/devices.c.

e0557c0d1a ARM: imx: move platform device code into mach-imx
It moves platform device code from plat-mxc into mach-imx.  Along with
that, header devices-common.h gets moved from plat-mxc/include/mach/
into mach-imx/devices/.

eb92044eb3 ARM i.MX3: Make ccm base address a variable
Instead of having a cpu_is_* in each ccm register access it
is more efficient to make it a variable.

3ac804e311 ARM: mx3: Let mx31 and mx35 enter in LPM mode in WFI
The LPM field of register CCMR is used to select the mode that the processor will run
when it goes to WFI.

When mx31 enters in WFI mode the LPM field is at its reset value of 0,
which configures the mx31 to enter in "wait mode".

On mx35, the LPM field on mx35 is also at 0 after reset, which corresponds
to "run mode" instead of "wait mode".

Instead of relying on the reset value of LPM to set the low power mode for
WFI, configure mx31 and mx35 to run in "wait mode"
