RE: [ECOS] ATMEL flash

Ok, since eCos has support for the AMD flash, then RedBoot should
automatically have that right?  Or maybe RedBoot does it's own flash
thing?

Probably.

We have separate flash drivers for amd and atmel flash. I notice that
the
atmel driver claims that erasing is not needed, and there's some
significant differences in flash_program_buf.

Unless I'm misremembering, it was supplied by Cirrus Logic as-is. I
don't
believe we've ever seen the source code for it.
