The number of gpio signal is packed inside CONFIG_SF_DEFAULT_CS macro
(shifted and or'ed with chip select), so it's incorrect to pass
that macro directly as an argument to gpio_direction_output() call.
Also, SPI driver sets the direction and initial value of a gpio,
used as a chip select signal, before any actual activity happens
on the bus.
So, it is safe to just remove the gpio_direction_output call,
that works incorrectly, thus making no effect, anyway.

PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.
By the way, remove some unused pad control definitions.
There is no change of behavior.
Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.

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.

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.

Rename all i.MX6 pad declarations to MX6_PAD_x, so a board
may support either i.MX6Quad/Dual (MX6Q) or i.MX6Dual-Lite/Solo
(MX6DL) by including the proper header.
Boards mx6qarm2, mx6qsabreauto, mx6qsabrelite, and mx6qsabresd
only support MX6Q, so they include mx6q_pins.h.

Adds support for HDMI, two LVDS panels and one RGB panel to
the SABRE-Lite board.
Displays supported:
HDMI - 1024 x 768 for maximum compatibility
Hannstar-XGA - 1024 x 768 LVDS (Freescale part number MCIMX-LVDS1)
wsvga-lvds - 1024 x 600 LVDS (Boundary p/n Nit6X_1024x600)
wvga-rgb - 800 x 480 RGB (Boundary p/n Nit6X_800x480)
Since the ipuv3_fb display driver currently supports only a single display,
this code auto-detects panel by probing the HDMI Phy for Hot Plug Detect
or the I2C touch controller of the LVDS and RGB displays in the priority
listed above.
Setting 'panel' environment variable to one of the names above will
override auto-detection.

On mxc, each SDHC instance has a dedicated clock, so gd->sdhc_clk is not
suitable for the multi-instance use case (initialization made directly with
fsl_esdhc_initialize()).
This patch fixes this issue by adding a configuration field for the SDHC input
clock frequency.

The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so
disable it globally for this architecture. This avoids setting no_snoop for all
i.MX boards, and it prevents setting a reserved bit of a reserved register if
fsl_esdhc_mmc_init() is used on i.MX, like in
arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init().
Since no_snoop was only used on i.MX, get rid of it BTW.

Each i.MX has its own gpio.h, defining the same structure.
The internal GPIO controller has the same layout
(at least for the register used by u-boot) and can be shared.

This is needed to support Freescale-supplied userspaces.
At the moment, both the IPU and VPU libraries provided by Freescale
in the "imx-lib" package contain routines which scrape the system
revision from /proc/cpuinfo. In the VPU library, this information is
used to load the proper firmware, allowing a single binary to be used
across various i.MX processors.

Define CONFIG_PHY_MICREL, and
minimize the tx clock delay.
There is an issue with 1000 baseTx mode on early revs
of the SabreLite boards. The center tap pin 9 of the mag RJ45
USB combo was connected to the 3.3 filtered supply. Letting
this pin float solved the problem. Symptoms of the problem
were packets with many extra zeroes tacked on the end, and random
bit flips causing a high rate of CRC errors. 10/100 baseTx worked
fine on all revs. To disable 1000 baseTx for these boards, simply
define the environment variable disable_giga. ie.
setenv disable_giga 1
