* 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
