* spl_relocate_stack_gd() - Relocate stack ready for board_init_r() execution

|
* Sometimes board_init_f() runs with a stack in SRAM but we want to use SDRAM
|
* for the main board_init_r() execution. This is typically because we need
|
* more stack space for things like the MMC sub-system.
|
*
|
* This function calculates the stack position, copies the global_data into
|
* place, sets the new gd (except for ARM, for which setting GD within a C
|
* function may not always work) and returns the new stack position. The
|
* caller is responsible for setting up the sp register and, in the case
|
* of ARM, setting up gd.
|
*
|
* All of this is done using the same layout and alignments as done in
|
* board_init_f_init_reserve() / board_init_f_alloc_reserve().
|
*
|
* @return new stack location, or 0 to use the same stack
