59 SPL starts off execution in SRAM and thus typically has only a small

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
64 board_init_f() completes, and before board_init_r() starts.

535 features provided by PMICs. In particular, voltage regulators can
536 be used to enable/disable power and vary its voltage. That can be
537 useful in SPL to turn on boot peripherals and adjust CPU voltage
538 so that the clock speed can be increased. This enables the drivers
