BTW: Do you really need to relocate code? You could just load the 2nd stage loader to ram from board_init_f, or?
I am passing the same address as I am executing from as the target for the relocation, so the relocation will not happen, instead BSS will be initialized. That's what I am calling it for. Initially I had my own routine for clearing BSS. Then I decided to re-use it from start.S
Ah, I see! Maybe you can add a comment here? Thanks!
Hmm, I actually porting a dm368 based board with nand_spl support (patches following soon), and there I have an empty bss section, so I can direct copy the u-boot image from nand to ram in board_init_f().
BTW, this series is not complete as far as SPL support is concerned. It doesn't even build due to many undefined references. It serves only as a prototype for the framework part.
Ah, Ok ...
