This is the second of two patches that will add support for the Embest 
SBC2440-II Board. This one adds the new code for the Embest SBC2440-II Board. 
Tested on an Embest SBC2440-II Board with u-boot in NOR flash, using tftp to 
copy kernel and root file system images from a tftp server, programming them 
into NAND flash and ensuring the kernel boots correctly at re-start. Also, 
MAKEALL was run for all ARM9 boards and no new warnings or errors were found.
