Great, thanks. > On my GTA02v3, I can't write, but that may be a configuration issue. > (See below.) On a GTA01Bv4, the NOR partition does not show up, so > there is no compatibility problem.

I don't really know why it should not be accepted by MTD_ROM even on GTA01 -- I tested it with giving the wrong start address in the platform stuff on a GTA-02 A4 here and it still had the logical physmap partition created. > Regarding the configuration, I think the patch sets more options that > we actually eed.

But surely you will need at least CONFIG_MTD_CFI=y and maybe some other ones around that. On the can't write thing, maybe you might not have the Flash paged in at all somehow and are getting a hit on MTD_ROM?
