My tests use several hundred KB of text (the C++ runtime) and a few tens of KB 
of bss+data; I don't know how to compute the remaining space, since I don't 
know the default sizes of flash & ram.

I do have some experience with linker scripts for Cortex-M devices, and I can 
tweak the projects generated by my template to allocate text in flash, but I 
have no experience with Cortex-A devices; if you tell me exactly at what 
address you want the program started, I can try to provide you a binary.
