fc40d01919 ARM: imx: change the way flexcan devices are registered
Group soc specific data in a global struct instead of repeating it for each
call to imxXX_add_flexcanX.  The structs holding the actual data are placed
in .init.constdata and so don't do much harm.  Compared to the previous
approach this reduces code size to call imx_add_flexcan.

Currently there is no platform data used in the driver.  In case this
changes and for consistency NULL is passed unused to the soc specific
functions.

0ea1293009 arm: return both physical and virtual addresses from addruart
Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

1ec1e82f25 dmaengine: Add Freescale i.MX SDMA support
This patch adds support for the Freescale i.MX SDMA engine.

The SDMA engine is a scatter/gather DMA engine which is implemented
as a seperate coprocessor. SDMA needs its own firmware which is
requested using the standard request_firmware mechanism. The firmware
has different entry points for each peripheral type, so drivers
have to pass the peripheral type to the DMA engine which in turn
picks the correct firmware entry point from a table contained in
the firmware image itself.
The original Freescale code also supports support for transfering
data to the internal SRAM which needs different entry points to
the firmware. Support for this is currently not implemented. Also,
support for the ASRC (asymmetric sample rate converter) is skipped.

I took a very simple approach to implement dmaengine support. Only
a single descriptor is statically assigned to a each channel. This
means that transfers can't be queued up but only a single transfer
is in progress. This simplifies implementation a lot and is sufficient
for the usual device/memory transfers.
