  Hi Sonic,

  Looks like you again choose a difficult patch set to try to upstream...

  After reading all the comments in this thread, I propose to split up 
the patch set as follows in order to get some progress on it.

1. Add blackfin CPU choice.
This patch adds a Target CPU configuration option and uses it to select a 
-m option for gcc.

2. Introduce target CPU revision.
Adds the possibility (in the general infrastructure, not 
blackfin-specific) to have a free-form CPU revision string and append it 
to the target CPU. Only Blackfin actually uses this option.

3. Introduce BINFMT_FLAT.
Just introduce the symbol and add options in blackfin to select it.

4. Introduce package-specific BINFMT_FLAT options.
I.e. <PKG>_FLAT_STACKSIZE

5. Introduce blackfin-specific Makefile
Probably needs more work.

6. Introduce NOMMU symbol
Probably needs more work.



  Regards,
  Arnout
