Re: [U-Boot] RFC: Aligning arch initialisation sequences

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
