NOR's too) do *not* support 32bit wide read's.  For example, if I 
remember correctly, the NAND driver for orion will let you read 32bits 
but write only 8bits at a time.  Other platforms are only 8bit wide in 
both direction.  I guess the 'slow' memcpy version is used as 
*everything* supports 8bit reads....I *guess* :)

For the NAND world, we have plat_nand and you can populate 
(read|write)_buf with your optimised version; of course you are using 
NOR so I have no idea if you have to treat that differently....
