Addressing for 8 and 16 bits is almost identical except in the 16 > bit case the LSB of the address is always 0. The confusion arose because > the addresses in the datasheet for the 16 bit mode are word addresses but > the CFI driver assumed they were byte addresses. > > I have only been able to test this on our Octeon boards which use either > an 8 or 16 bit bus.

Then it should have V2 tag and patch history. Amicalement, -- Albert.
