Fabio Estevam 0d1ea05210 wandboard: Switch to SPL support
Currently we need to build one U-boot image for each of the wandboard
variants: quad, dual-lite and solo.

By switching to SPL we can support all these variants with a single binary,
which is very convenient.

Based on the work from Richard Hu.

Tested kernel booting on the three boards.

U-Boot for Wandboard
--------------------
This file contains information for the port of U-Boot to the Wandboard.
Wandboard is a development board that has three variants based on the following
SoCs: mx6 quad, mx6 dual lite and mx6 solo.
For more details about Wandboard, please refer to:

Building U-boot for Wandboard
-----------------------------
To build U-Boot for the Wandboard:
$ make wandboard_config
$ make
Flashing U-boot into the SD card
--------------------------------
- After the 'make' command completes, the generated 'SPL' binary must be
flashed into the SD card;
$ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
(Note - the SD card node may vary, so adjust this as needed).
- Flash the u-boot.img image into the SD card:
sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
- 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.
