Simon Glass 00caae6d47 env: Rename getenv/_f() to env_get() We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

How to use U-Boot on Grinn's liteBoard
--------------------------------------

- Build U-Boot for liteBoard:

$ make mrproper
$ make liteboard_defconfig
$ make

This will generate the SPL image called SPL and the u-boot.img.

- Flash the SPL image into the micro SD card:

sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync

- Flash the u-boot.img image into the micro SD card:

sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync

- Jumper settings:

S1: 0 1 0 1 1 1

where 0 means bottom position and 1 means top position (from the
switch label numbers reference).

- Insert the micro SD card in the board.

- Connect USB cable between liteBoard and the PC for the power and console.

- U-Boot messages should come up.
