552a848e4f imx: reorganize IMX code as other SOCs
Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.

ef47683646 cmd/fdt: add possibilty to have 'extrasize' on fdt resize
Sometimes devicetree nodes and or properties are added out of the u-boot
console, maybe through some script or manual interaction.

The devicetree as loaded or embedded is quite small, so the devicetree
has to be resized to take up those new nodes/properties.

In original the devicetree was only extended by effective
4 * add_mem_rsv.

With this commit we can add an argument to the "fdt resize" command,
which takes the extrasize to be added.

edf0093732 mx6: ddr: Allow changing REFSEL and REFR fields
Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
REFR fields of the MDREF register as 1 and 7, respectively for
DDR3 and 0 and 3 for LPDDR2.

Looking at the MDREF initialization done via DCD we see that
boards do need to initialize these fields differently:

$ git grep 0x021b0020 board/

So introduce a mechanism for users to be able to configure
REFSEL and REFR fields as needed.

Keep all the mx6 SPL users in their current REF_SEL and REFR values,
so no functional changes for the existing users.

f8de60bd58 ARM: board: cm_fx6: fix mtd partition fixup
ft_board_setup may return early in the case that the board revision
cannot be obtained. In that case it is assumed that no revision
specific correction in the fdt is neccessary. But the mtd partitions
will not be fixed up either altough they are not revision specific.

Move the call to fdt_fixup_mtdparts in front of the revision specific
part to ensure that the partitions are fixed up even if the board
revision cannot be obtained.

While on it, fix a spelling mistake in a comment introduced by the
same commit.

62d6bac660 ARM: board: cm_fx6: fixup mtd partitions in the fdt
The cm-fx6 module has an on-board st,m25p compatible spi flash chip
used for U-Boot (binary & environment). Overwrite the partitions in
the device tree by the partition table provided in the mtdparts
environment variable, if it is set.

This allows to specify a kernel independent partitioning in the
environment and provides a convient way for the user to adapt the
partition table.

c133c503ac ARM: board: cm-fx6: fix mmc for old revisions of utilite
Old revisions of Utilite (based on cm-fx6) do not have a dedicated
card detect pin. But the card is removable by the user and card
detection can be realized with polling (e.g. supported by Linux).

Add the broken-cd property to the mmc device tree instead of the
non-removable property to make card detection possible if polling
is supported.

d6276ab10d arm: mx6: cm-fx6: force host mode on usb controller
On some CM-FX6 modules U-Boot attempts to configure the usb0 controller in
device mode, which renders it unavailable:
	USB0:   Port not available.
and also causes usb stop to report an error
	EHCI failed to shut down host controller.

This happens mostly on MX6 Dual based modules, and is caused by the USBPHY_CTRL
register reporting USBPHY_CTRL_OTG_ID to be 1, even when it is pulled down.
Since we do not support device mode in cm-fx6 u-boot, force all controllers to
be configured as hosts.

The new function does not init display if the environment variable "panel" is

Collateral changes:
- Don't use the global displays array (it's CONFIG_IMX_VIDEO_SKIP specific).
- Don't use detect_hdmi(), since env controlled init makes it unnecessary.

* Provide existing routines for auto loading the splash image from the

e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

53b7f18044 mx6: Use a common SPL configuration file
Many boards use a minimal .cfg file in the SPL case.

Introduce spl_sd.cfg so that we can reuse it.

0b23780ff0 arm: mx6: cm_fx6: detect 1GB DRAM correctly on solo
The 1GB DRAM configuration on mx6 solo uses 2 chip selects, but
the code tests 1GB DRAM configuration as if it is all present on one
chip select, and thus cannot see the full range of available memory.

Refactor the check to detect 1GB DRAM correctly.

2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

86256b796e dm: move platform data headers to include/dm/platform_data
The platform_data definitions are generally referenced from both
drivers and board files.  That is why header files defining
platform_data sturectures are placed in "include" directory,
but our top level "include" directory is already too cluttered.

Let's collect platform_data definitions under the directory
"include/dm/platform_data" like Linux gathers ones around under
"include/linux/platform_data".

This commit moves two header files:

  include/serial_mxc.h -> include/dm/platform_data/serial_mxc.h
  include/serial_pl01x.h -> include/dm/platform_data/serial_pl01x.h

8f488c1bac arm: mx6: cm_fx6: use gpio request
Use gpio_request for all the gpios that are utilized by various
subsystems in cm-fx6, and refactor the relevant init functions
so that all gpios are requested during board_init(), not during
subsystem init, thus avoiding the need to manage gpio ownership
each time a subsystem is initialized.

The new division of labor is:
During board_init() muxes are setup and gpios are requested.
During subsystem init gpios are toggled.
