Access Nand flash using uboot while in NOR boot mode

Ayyappan
Hi,

Can we access NAND flash and create partition and write images in NAND
flash with uboot bootloader while in NOR boot mode in mini2440?

What will be the physical address for NOR flash starts and ends with while
in NOR boot mode?So that i have to take care that physical address for NOR
flash and NAND flash does not overlap. Because SDRAM physical address
starts with 0x30000000 which lies in 1GB NAND flash memory address range.

Please help!
