The physical address is defined by your board design. It depends on the 
chipselect, addressdecoding...
The virtual address is the address which is used inside the kernel driver 
code. This address is translated by the MMU into a physical address.
e.g.
MTD driver uses virtual address 0xf0000000 according to chip-mapping. So a 
read from 0xf0000000 is a read from the physical address 0x30000000, which is 
the physical hardware address of the flash chip.
