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. _FLAT_STACKSIZE 5. Introduce blackfin-specific Makefile Probably needs more work. 6. Introduce NOMMU symbol Probably needs more work.
