97976e223b ARM: mx3: use .init_early to initialize cpu type, reset address and iomuxer
This used to be done in .map_io which is supposed to only setup the

08ff97b521 ARM: imx: use MXxy_IO_P2V macros to setup static mappings
This makes less code rely on the virtual constants.

To further simplify code and reduce the needed boilerplate when
defining the static mappings a new helper macro is defined in
mach/hardware.h.

9524705c86 MX35: Fix bogus L2 cache settings
i.MX35 CPUs marked with "MCIMX357CJQ5C M99V CTHA0943B" are coming with bogus
L2 cache settings. If these settings are kept unmodified prior enabling the L2
cache the CPU runs amok immediately when its enabled.

This fix should not hurt already working CPUs, as they are using the written
register value already.

Its currently unknown if its possible to detect the production lot from the
software to fix only affected CPUs.

While at it, make sure that mxc_init_l2x0 is only executed on i.MX31/35

84659ab585 imx: move gpio init after to irq init
The commit 9a763bf "get rid of mxc_gpio_init" changed gpio_init
and irq_init sequence. Usually we will call set_irq_chained_handler
in gpio_init functions, this should be called after the irq_init
called, otherwise the chained irq can't get propoer irq_chip and this
irq will remain masked even we called set_irq_chained_handler.

This function is defined once for each imx family and so is in the way
when compiling a kernel for more than one SoC.

e94c4c3449 ARM: MX3: make CPU revision number detection work on all boards
Commit 52939c03 (ARM: MX3: fix CPU revision number detection) started
using the CPU's SREV register for revision number detection. This
makes it mandatory to have a valid SPBA0 mapping. Add this to the
global map_io code instead of adding multiple copies for each board.

324c1aa3df fix compilation of i.MX31 platforms
mxc_iomux_v3_init() is defined in arch/arm/plat-mxc/iomux-v3.c, which is
not linked for i.MX31 and produces an undefined reference error. Fix this
by building the offending code only for i.MX35.

52c543f90c [ARM] 4461/1: MXC platform and i.MX31ADS core support
This patch adds the foundation pieces for
the Freescale MXC platforms, including
i.MX2 and i.MX3 based systems.

The bare-bones MX31 support in this patch
boots to the rootdev panic with 8250 serial
console configured "console=ttyS0,115200".
It assumes that Redboot is the boot loader.
