Correct.

Agreed.

Well, let's split development and testing from the final committing.

I suggest you provide what you can in  single patch, and we put this
in a separate branch of the git repository.  Heiko and me may then add
support for the precessors we used for testing, i. e. arm1136 and
armv7.  Hopefully others will pick up from there for the remaining
processors.

When committing to mainline (or to u-boot-arm) I can sqash all the
processor related commits into a single one.


Umm... is my understanding correct that we can drop the whole
CONFIG_SYS_ARM_WITHOUT_RELOC stuff then, too?

Best regards,

Wolfgang Denk

Every revolutionary idea - in science, politics, art, or  whatever  -
evokes three stages of reaction in a hearer:
  1. It is completely impossible - don't waste my time.
  2. It is possible, but it is not worth doing.
  3. I said it was a good idea all along.
