==> And this is not a good approach, you want the S/W to use the first 256 kB to store initial boot, U-boot and environment. The AT91SAM9 chips will use the first 8 kB sector for the AT91bootstrap, and that should have protection separate from U-Boot code. AVR32 boot ROM will boot from a higher address and use the 8 kB sector at address zero as environment. Both will need to have a S/W partitioning scheme added with separate protection for each partition. This partioning scheme exists today.
sorry, i didnt mean to imply i thought this limitation was something to be written in stone. i understand perfectly why you would want this flexibility, so i can take a look. rather than making general statements, can you please provide a concrete list of all relevant examples you know of.
Ulf: can you at least follow up to this so i have a goal to work towards ? maybe i'll demand some sample parts if you want support ! :) -mike
