bad40e089f mx6: Fix definition of IOMUXC_GPR12_DEVICE_TYPE_RC
mx6 reference manual incorrectly states that the DEVICE_TYPE field of
IOMUXC_GPR12 register should be configured as '0010' for setting the PCI
controller in RC mode. The correct value should be '0100' instead.

This also aligns with the same value used in the mx6 pci kernel driver.

8d05b161fc mx6: add structs for mmdc and ddr iomux registers
Add memory-mapped structures for MMDC iomux and configuration. Note that whi
the MMDC configuration registers are common between the IMX6DQ
(IMX6DUAL/IMX6QUAD) and IMX6SDL (IMX6SOLO/IMX6DUALLITE) types the iomux
registers differ. This requires two sets of structures.

Add structures to describe DDR3 device information, system information
(memory layout, etc), and MMDC calibration registers that can be used to
configure the MMDC dynamically.

We define these structures for SPL builds instead of including mx6q-ddr.h an
mx6dl-ddr.h which use the same namespace and are only useful for imximage cf
files.

    MX6Q   - for boards targeting i.MX6Q or i.MX6D
    MX6DL  - for boards targeting i.MX6DL
    MX6S   - for boards targeting i.MX6S
    MX6QDL - for boards that support any of the above with
             run-time detection

Pad declarations will be MX6_PAD_x for single-variant boards
and MX6Q_PAD_x and MX6DL_PAD_x for boards supporting both
processor classes.

85b8c5c4bf Merge branch 'iu-boot/master' into 'u-boot-arm/master'

	board/ppcag/bg0900/Makefile
	drivers/bootcount/Makefile
	include/configs/omap4_common.h
	include/configs/pdnb3.h

Makefile conflicts are due to additions/removals of
object files on the ARM branch vs KBuild introduction
on the main branch. Resolution consists in adjusting
the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:

	board/compulab/common/Makefile
	board/udoo/Makefile

include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.

include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.

Note: 'git show' will also list two files just because
they are new:

	include/configs/am335x_igep0033.h

Some _CLKGATE_MASK and _FRAC_MASK macros were wrong for PFD_480
and the PFD_528 macros were missing.

Fortunately, the incorrect macros weren't being used.

Since both the PFD_480 and PFD_528 registers have the same
structure, and the fields are identical for [0..3] in bytes
[0..3], so a single set of macros will suffice.

10f779da54 imx: nitrogen6x: mx6qsabrelite: Add support for DVI monitors
A little background is probably appropriate for this patch.

Since "the beginning" of usage of the SABRE Lite and Nitrogen6x
boards, DVI detection has been somewhat broken.

Some (most) DVI monitors don't produce the "HPD" bit in
the PHY_STAT0 register, but do show proper toggling of the
RX_SENSE0..3 bits.

Creating a new the bit-mask to include all five bits and
modifying the 'hdmidet' command and internal detection
routines allows these monitors to function properly in U-Boot.

A related patch to our kernels allows things to work under
Linux:
