Dear Wolfgang Denk,
> I think you would quickly find this becoming a pretty serious pain.
Yes, I saw that soon after my first post:)
But whats left of my ideas is the following:
in asm: set stack to end of SRAM (or whatever)
(board-config.h would not subtract GENERATED_GBL_DATA_SIZE
anymore)
in c:
board_early_init(void)
{
gd_t auto_gd;
gd = &auto_gd;
That would rid us of all alignment concerns:
Setting stack to end of initial storage will certainly
be aligned, and the auto_gd will be aligned as the
toolchain deems necessary.
We would not need GENERATED_GBL_DATA_SIZE anymore.
The auto_gd space on stack will be valid even into the call
to relocate_code.
Best Regards,
Reinhard
