Benoît Thébaudeau 7e2173cf82 imx: iomux-v3: Include PKE and PUE to pad control pull definitions 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.

U-Boot for Wandboard
--------------------

This file contains information for the port of U-Boot to the Wandboard.

Wandboard is a development board that has two variants: one version based
on mx6 dual lite and another one based on mx6 solo.

For more details about Wandboard, please refer to:
http://www.wandboard.org/

Building U-boot for Wandboard
-----------------------------

To build U-Boot for the Wandboard Dual Lite version:

$ make wanboard_dl_config
$ make

To build U-Boot for the Wandboard Solo version:

$ make wanboard_solo_config
$ make

Flashing U-boot into the SD card
--------------------------------

- After the 'make' command completes, the generated 'u-boot.imx' binary must be
flashed into the SD card;

$ sudo dd if=u-boot.imx of=/dev/mmcblk0 bs=512 seek=2; sync

(Note - the SD card node may vary, so adjust this as needed).

- Insert the SD card into the slot located in the bottom of the board (same side
as the mx6 processor)

- Connect the serial cable to the host PC

- Power up the board and U-boot messages will appear in the serial console.
