The goal of this series is to scrub the start.S files which have proliferated across arch/arm and eliminate code redundancy.
Currently this series only factorizes the C runtime framework, that is, the assembly code responsible for setting up the C environments needed by board_init_*() and relocate_code().
Further factorization is possible: relocate_code() can be moved out and possibly rewritten in C now that it has plain C function semantics; exception handlers should also be pretty much cpu-independent.
Eventually, start.S files should disappear or contain CPU-specific code only.
The new C runtime setup sequence has been validated step by step on target versatileqemu using toolchain ELDK4.2.
The whole changes have been build-tested across all ARM targets using MAKEALL -a arm.
Changes in v3:
- various clarifications and typo fixes
- fixed wrong LED calls conditional
- fixed open comment eating some code
- fixed code overrun in SPL case
Note there is no warning for using 'deprecated' NAND_SPL yet. I'm running full MAKEALL -a arm on this and it'll be added in v4 depending on results.
Amicalement,
