Theoretically, yes. If it actually just is a standard Cortex-M3 core 
then it should work fine, and you would only have to add the RTL stubs, 
and compiler/arm/cpuinfo.pas+t_embed.pas entries for the cores.

However, I have a suspicion that it won't be that easy since it's a 
complex setup, and it's made by TI :)
