58 | help | |
59 | SPL starts off execution in SRAM and thus typically has only a small | |
60 | stack available. Since SPL sets up DRAM while in its board_init_f() | |
61 | function, it is possible for the stack to move there before | |
62 | board_init_r() is reached. This option enables a special SDRAM | |
63 | location for the SPL stack. U-Boot SPL switches to this after | |
