| 489 | * |
| 490 | * Sometimes board_init_f() runs with a stack in SRAM but we want to use SDRAM |
| 491 | * for the main board_init_r() execution. This is typically because we need |
| 492 | * more stack space for things like the MMC sub-system. |
| 493 | * |
| 494 | * This function calculates the stack position, copies the global_data into |
Albert ARIBAUD | 85260bb | 2015-11-25 17:56:33 +0100 | [diff] [blame] | 495 | * place, sets the new gd (except for ARM, for which setting GD within a C |
| 496 | * function may not always work) and returns the new stack position. The |
| 497 | * caller is responsible for setting up the sp register and, in the case |
| 498 | * of ARM, setting up gd. |
| 499 | * |
| 500 | * All of this is done using the same layout and alignments as done in |
| 501 | * board_init_f_init_reserve() / board_init_f_alloc_reserve(). |
