I wrote: system RAM.  On most systems this is SDRAM (or rather DDR
these days).

James Chargin already explained most of the details - note that his
explanation is pretty much genral; see also section "Memory Management" 
in the U-Boot README file.

Your SA application uses both the malloc arena and the stack that has
been set up by U-Boot, so stack size is really only limited by the
size of the System RAM.

Best regards,
