Hi Kevin,

Implementation based on the existing u-boot support for S3C2410-based boards. u-boot programmed into NOR flash.
Tested on an SBC2440-II Board using tftp to copy the files from a server and programming them into NAND flash.
MAKEALL used to build all LIST_ARM9 targets only - no other architectures built as the changes only affect ARM9-based boards.
