I understand that the Cortex A8 which powers the AM3x features the full 
32 bit "ARM" instruction set plus the 16 Bit "Thumb" instruction set 
plus several enhancements. Thus code created by FPC/ARM  should just run 
out of the box.

In the Lazarus mailing list, we lately discussed how to special do stuff 
like "atomic instructions" and "Futex without libc binding". Here 
ARM-Linux offers a shared userland page with functions that are always 
provided in a version optimized for the CPU subarch we are running on. 
Using same in the RTL instead of doing our own (non sub-arch optimized 
at runtime) code would be a nice enhancement for the RTL
