I think we should not simply re-add the old mess, but clean ip up
before. Also, we should only add things that are stilkl needed and
will be actively tested and maintained.
Alll the 4xx stuff has no place here and should be thrown out.
File structure should be cleaned up - drivers should be placed where
they belong.
Stuff that is most certainly unmaintained and/or broken (bedbug
support, test_burst, PCMCIA support, USB support) should be omitted
as well.
We should not re-add this stuff, but clean up at least these things
before.
Actually I also agree with Heiko that we should fix things like
(lack of) using I/O accessors before re-adding the code. Most
modern compilers will most likely generate incorrect code in a large
number of places - this has only gone unnoticed for a long time due
to lack of testers.
I have to admit that it is kind of breaking my heart to see 8xx go,
as this is where it all started - this was the first code of this
project, long before the name U-Boot came up. But formally I'm
still maintainer of this code, and in it's current form I want to
see it removed and gone. If we re-add it, it really has to meet
today's standards.
NAK!
Best regards,
Wolfgang Denk
