When embedding the environment, you must set up a specific memory mep.
This is done in the linker script, so this definition is usually found
there.

Out-of-tree code is always a pain. But the real problem comes from the
complexity of the hardware we have to deal with in the boot loader.
After all, we have to do all the low-level initializations all higher
software levels (including Linux) just take for granted.
