Add IRAM(Internal RAM) allocation functions using GENERIC_ALLOCATOR.
The allocation size is 4KB multiples to guarantee alignment. The
idea for these functions is for i.MX platforms to use them
to dynamically allocate IRAM usage.

Instead of having a platform device defined in a devices.c and register
it in the machine file allocate it dynamically.  This reduces the size
of needed memory as the new function is discarded after init and only
the existing devices are created.
Signed-off-by: NUwe Kleine-König <u.kleine-koenig@pengutronix.de>

This should be used instead of hard coding the corresponding platforms.
The feature test macro is needed to support different SOCs in a single
kernel image.  While at it rename dma-mx1-mx2 to dma-v1 as mx25 doesn't
use it and so the mx2 part is wrong and move the header to
arch/arm/mach-imx.

Freescale i.MX51 processor uses a new interrupt controller. Add
driver for TrustZone Interrupt Controller
Signed-off-by: NAmit Kucheria <amit.kucheria@canonical.com>

The old driver has the number of SSI units in the system hardcoded,
does not make use of the device model and works only on i.MX21/27.

This driver replaces it. It works in DMA mode on i.MX21/27 and using
an FIQ handler on other systems. It also supports AC97 mode of
the SSI units.

When all remaining users are fixed this allows including the soc

The Freescale MX27 and MX31 SoCs have a EHCI controller onboard.
The controller is capable of USB on the go. This patch adds
a driver to support all three of them.

Users have to pass details about serial interface configuration in the
platform data.

The USB OTG core used here is the ARC core, so the driver should
be renamed and probably be merged with ehci-fsl.c eventually.

only check for the cpu type if more than one architecture is compiled
in.

 - i.MX1 (tested)

 - i.MX3 (i.MX31 (tested))

timer do not follow the platform device rules. So it does only work if
timer 1 can be accessed on all CPUs at the same address.

Internal clock path handling for the mxc CPUs.

Changed against the original Freescale code (and against clocklib for example):
 - clock rate is always calculated whenever one ask for the current rate
   (means struct clk has no more a member called "rate"). So switching the PLL
   base frequency will propagate immediately to all other clocks that are
   depending on this frequency.
