Does anybody plan to rework Intel 28FXXX ('v1')? I'm not expect in v2
and want to ask, Is there known limitations or issue for this line? The
driver is marked as 'legacy' in the latest ChangeLog entry. Is it the
verdict?

Please, to explain

find packages/devs/flash -type d -name \*v2 -printf %f\\n
synthv2
am29xxxxxv2
stratav2

Does this triplet mean 'all' for now? I understood so that we will have
3 bases of the version 2 eCos FLASH API? Is it right or I did miss
something?

Here http://ecos.sourceware.org/docs-latest/ref/io-flash.html is out
dated chapter 26 only. It's need to build documentation from CVS
sources. New documentation has nice chapters 26, 27, 28, 29 about.
Thanks a lot to authors! If anybody has no TeX, Latex and other bloat
packages installed, I put just now all built PDF docs, it's here:

Thank you.

All the best,

Sergei
