how to implement a "fis load" or "load fis" command in RedBoot?

[oliver munz @ s p e a g]

Hello

My Target has only 64kByte RAM and so it's impossible to load my programs in 
the RAM because there is no space left. So I need a possibility to load 
images direct to the flash and run it there.

I see two possibilitis in modifying the RedBoot.
1. Writing a "fis create xmodem" command
2. Make the "load" command writing direct in the flash-space...

I think the second option is easyer to implement.

Has any body done somting like that? Or has any body a hint were to start?

Thanks Oli
