38e7007725 mx6: Fix get_board_rev() for the mx6 solo case
When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev()
returns 0x62xxx, which is not a value understood by the VPU
(Video Processing Unit) library in the kernel and causes the video playback to
fail.

The expected values for get_board_rev are:
0x63xxx: For mx6quad/dual
0x61xxx: For mx6dual-lite/solo

So adjust get_board_rev() accordingly and make it as weak function, so that we
do not need to define it in every mx6 board file.

aad4659a2f mmc: i.MX6: fsl_esdhc: Define maximum bus width supported by a board
Maximum bus width supported by some i.MX6 boards is not 8bit like
others. In case where both host controller and card support 8bit transfers,
they agree to communicate on 8bit interface while some boards support only 4bit interface.
Due to this reason the mmc 8bit default mode fails on these boards. To rectify this,
define maximum bus width supported by these boards (4bit). If max_bus_width is not
defined, it is 0 by default and 8bit width support will be enabled in host
capabilities otherwise host capabilities are modified accordingly.

It is tested with a MMCplus card.

b33426caf6 mxs: spl_mem_init: Align DDR2 init with FSL bootlets source
Currently the following kernel hang happens when loading a 2.6.35 kernel from
Freeescale on a mx28evk board:

RPC: Registered tcp transport module.
RPC: Registered tcp NFSv4.1 backchannel transport module.
Bus freq driver module loaded
IMX usb wakeup probe
usb h1 wakeup device is registered
mxs_cpu_init: cpufreq init finished
...

Loading the same kernel using the bootlets from the imx-bootlets-src-10.12.01
package, the hang does not occur.

Comparing the DDR2 initialization from the bootlets code against the U-boot
one, we can notice some mismatches, and after applying the same initialization
into U-boot the 2.6.35 kernel can boot normally.

Also tested with 'mtest' command, which runs succesfully.

477393e787 Tegra114: Dalmore: Add pad config tables/code based on pinmux code
Pad config registers exist in APB_MISC_GP space, and control slew
rate, drive strengh, schmidt, high-speed, and low-power modes for
all of the pingroups in Tegra30. This builds off of the pinmux
way of constructing init tables to configure select pads (SDIOCFG,
for instance) during pinmux_init().

Currently, no padcfg entries exist. SDIO3CFG will be added when the
MMC driver is added as per the TRM to work with the SD-card slot on
Dalmore E1611.

f31a5443a8 Tegra114: Dalmore: Always use DEFAULT instead of DISABLE for lock bits
The pinmux code issues a warning if the caller attempts to disable the
lock bit in a pinmux register, since this is impossible (once it's
locked, the only way to unlock it is to reset the device/pmt controller).

The I2C/DDC/CEC/USB macros expect a lock setting to be passed in,
and the previous setting of DISABLE caused the pinmux table parsing
code to issue the warning. Changing the lock bits in these table
entries to DEFAULT (i.e. don't touch it) fixes this.
