Move all the C runtime setup code from every start.S in arch/arm into arch/arm/lib/crt0.S. This covers the code sequence from setting up the initial stack to calling into board_init_r().
Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc).
Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed.
Signed-off-by: Albert ARIBAUD albert.u.boot@aribaud.net --- Changes in v5: - Fixed build on non-ARM architectures
Changes in v4: - fixed bhs into blo in BSS init loop - switched from explicit literals to '=target' notation - fixed location of GD in initial environment - stopped SPL boot sequence at calling board_init_f
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
Changes in v2: - moved description from cover letter to patch commit msg - added note about tests in the cover letter - fixed baords with CONFIG_SPL but not CONFIG_SPL_STACK
