For moving thigns around, I usually put them in separate ELF sections
(I define __sram and __sramdata macros, similar to the kernel
equivalent section macros) and then use the ld script to link
those sections at different addresses than where they are loaded.
Then, at boot, you need a bit of code that copies those to their
final address.
