| * 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 |
