[ECOS] Flash infrastructure rework
Wed Aug 4 19:49:00 GMT 2004
Is there the possibility of adding it as its own CYGPKG_NEW_FLASH package?
Regardless, I might want to beta test it for you -- I have been working with
a board that has two different FLASH devices on it. I'll have to give that
one a little think.
