Juan Castillo 9784dbda11 Add basic NOR flash driver for ARM platforms
FVP and Juno platforms include a NOR flash memory to store and
load the FIP, the kernel or a ramdisk. This NOR flash is arranged
as 2 x 16 bit flash devices and can be programmed using CFI
standard commands.

This patch provides a basic API to write single 32 bit words of
data into the NOR flash. Functions to lock/unlock blocks against
erase or write operations are also provided.
