CONFIG_MTD_PHYSMAP_START is the physical address of your NOR FLASH
CONFIG_MTD_PHYSMAP_LEN is the size of your NOR FLASH in bytes

You can enable commandline partition parsing and provide the partition
info on the kernel commandline. There is some "documentation" in the
code. :)

Another option is to write our own board driver (by copying one which
fits your needs closely and tweaking it for your board)

NAND is a different beast. You will have to write a board driver (same
procedure as above), but there's some documentation available.
