- Convert the non-relocation part of board_init_f to spl_board_init, turn on CONFIG_SPL_BOARD_INIT in the configs. - Remove duplicated code. - Add spl_boot_device() that returns the statically chosen boot device.
Signed-off-by: Tom Rini trini@ti.com --- Changes in v2: - Add CONFIG_SYS_SPL_MALLOC_START / SIZE defines from Christian Riesch - Add arch/arm/cpu/arm926ejs/davinci/config.mk to build u-boot.ais
Changes in v3: CONFIG_SPL_FRAMEWORK perform early init. Fixes the cannot reset problem. - Make u-boot.ais use u-boot.img not u-boot.bin, now that it uses - Make use of board_init_f being a weak function now so that we can
