Did anybody actually test this rewrite extensively? I don't  remember
any feedback?

After checking in some previous patches, you patch does not apply any
more. Do you think you can provide an update?

Either the code is board specific, and belongs to a board  directory,
or  it  is generic for many boards using the same CPU, then it is CPU
specific and belongs to the cpu directory.

I don't see a need for this.

the latest patch (the 3rd) provides just few changes respect to the 2nd one:
- board init invokes SetAsynchMode();
- bi_arch_number has been updated with the master database hosted at 
http://www.arm.linux.org.uk/developer/machines/
- fixed PCDR clock settings for TFT LCD panel Sharp LQ050Q5DR01
- copy of ramdisk from Flash to RAM before booting Linux kernel (we chose 
to not patch the kernel 2.6 basically for tight schedule constraints)

I just searched the archieve:
Dave Ellis gave a feedback (3rd May) for an earlier version of the
rewritten code. And Wolfgang Denk mentioned on 7th June that the code
doesn't compile (for the PPChameleon Board).

Right now the patch from 5th May doesn't even apply to the current CVS.

Pantelis or Dave, could you give us any info about the status of the
code? Are you still using your patch? Is there a newer version that
applies to the current CVS? I am willing to do some testing...

Best regards,
Stefan

Well, it would definitely help if you followed the  instructions  for
submitting  patches  as given in the README (read: I will reject this
patch until you do).

Problems:

* There is no CHANGELOG entry nor any description what the patch does
  or why.

* There is no description that there is more than just one patch;  in
  your  posting  you wrote "download the latest patch" - how should I
  know if the "-3" suffix indicates a version or a sequence number?

* Even if I try to apply the two other patches  (which  you  did  not
  mention in your posting) it does not work. An I wrote: the code has
  changed  a  lot  -  there  is  for  example  no  such  directory as
  cpu/mc9328/
