uboot-phytec

Lots of new stuff:
 * Debug message can be turned on and off.
 * Waiting for events now times out.
 * Implemented RESET command.
 * Added appropriate nand_bbt_descriptor and nand_oobinfo.

Remaining Problems:
 * Read Status still behaves weird an returns invalid stuff sometimes.
 * ECC Placement does not respect our scheme in nand_oobinfo.
