I kind of like the idea to create a new set of commands for accessing such 
board specific NOR FLASH (can be used on "normal" NOR FLASH as well). Perhaps 
we could make it "generic" in a way that it can be used for all kind of "MTD 
devices". How about this "mtd" commandset:

Select MTD NOR device #1 (2nd NOR device):
=> mtd device nor 1

Or via mtdparts/mtdids:
=> mtd device nor0

After this selection the "mtd" commands could be used to access the FLASH 
device:

=> mtd erase
=> mtd read
=> mtd write

This way all these commands would be FLASH type independent. We could perhaps 
consolidate all those multiple commandsets (nand, onenand etc) into this one 
over time.

Best regards,
Stefan
