Sorry about that, it's not the 16x parts that have what AMD calls the "Flexible
Sector Achitecture", it's the 800 parts. There's a comment in the mtd memory
mapped code that says that the 800 parts aren't supported. Now that I've taken
a closer look, I don't think that the amd_flash driver even depends on the
memory mapped code. Is this true?
What I really meant to say was that it looks like the big difference between
the lv160 and the dl162/163 is that the 162/163 supports simultaneous
read/write capability. It doesn't seem like this feature would warrant a
driver change. Besides, if the kernel runs from RAM, then this feature never
gets used after the kernel is booted. So, does anyone see any reason why the
lv160 driver wouldn't work for the dl162/163 chips?
