Introduce 'mx28evk_nand' target for saving environment variables into NAND. The mx28evk board does not come with a NAND flash populated from the factory. It comes with an empty slot (U23), which allows the insertion of a 48-pin TSOP flash device. Tested with a K9LBG08U0D.

Environment Storage
|
|
-------------------
|
|
|
|
There are two targets for mx28evk:
|
|
|
|
"make mx28evk_config" - store enviroment variables into MMC
|
|
|
|
or
|
|
|
|
"make mx28evk_nand_config" - store enviroment variables into NAND flash
|
|
|
|
Choose the target accordingly.
|
|
|
|
Note: The mx28evk board does not come with a NAND flash populated from the
|
|
factory. It comes with an empty slot (U23), which allows the insertion of a
|
|
48-pin TSOP flash device.
|
|
|
|
Follow the instructions from doc/README.mx28_common to generate a bootable SD
|
|
card.
|
|
|
|
Insert the SD card in slot 0, power up the board and U-boot will boot.
