Yes the main SPL is using CONFIG_SPL_FRAMEWORK. But the low level board
initialization is done in s_init (via lowlevel_init).

This other boot helper is basically only calling s_init() and then
returns to the caller with the board now configured in a reasonable
state allowing it to accept u-boot.bin to be uploaded into SDRAM.
