 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.

+mx28evk does not come with SPI NOR flash populated from the factory either.
+It is possible to solder a SOIC memory on U49 or use a DIP8 on J89.
+To get SPI communication to work R320, R321,R322 and C178 need to be populated.
+Look in the schematics for the proper component values.
 
-Insert the SD card in slot 0, power up the board and U-boot will boot.
