CONFIG_SPL_PAD_TO
- Linker address to which the SPL should be padded before
- appending the SPL payload.
+ Image offset to which the SPL should be padded before appending
+ the SPL payload. By default, this is defined as
+ CONFIG_SPL_MAX_SIZE, or 0 if CONFIG_SPL_MAX_SIZE is undefined.
+ CONFIG_SPL_PAD_TO must be either 0, meaning to append the SPL

CONFIG_SPL_TARGET
Final target image containing SPL and payload. Some SPLs
