PPC boards basicly have a board_init_f(), doing initialization, then relocating the code from flash to ram using relocate_code(), and then continue in ram with board_init_r().
I can't find anything like this in the ARM based files?
Try again - it's all there (only, the naming is different)!
How is that done? Is that the same for all ARM boards?
Execution starts in cpu/<your-cpu-here>/start.S which does the initial initialization, helped by board/<your-board-here>/memsetup.S When memsetup.S has set up the (S)(D)RAM, start.S relocates the code from flash to RAM and continues with start_armboot() in lib_arm/board.c
This is practically identical for all ARM boards, yes (but watch out for the details ;-).
