[U-Boot-Users] u-boot on a quad processor board
I have u-boot running concurrently on all 4 processors on our multi-processor board. Anyone interested in this. If so I will clean up my code and submit a patch. Also, my next task is to keep u-boot in flash (with a limited number of commands) if the sdram fails. This is will allow the user to peek and poke from the command line to configure the sdram controller or debug sdram so it (u-boot) can complete the booting process to sdram. This the only short coming I can see that u-boot has.:-)

How did you implement this?

Sure, please make your patch available. Even if it is not too intrusive (which I am afraid it might be) to go into the mainstram version it will be useful to others.

Umm... This will require significant changes to the code, as without RAM there is no real stack or writable .data or .bss segments.
