Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL framework, enable on all of the previously using boards. We move the spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave the NAND one in-place as we plan to replace it later in this series.
We use common/spl to avoid linker problems with respect to merging constant strings in objects. Otherwise all strings in common/ will be linked in and kept which grows SPL in size too much.
Signed-off-by: Tom Rini trini@ti.com --- Changes in v2: - Place files into common/spl (due to gcc bug #54303) and include/spl.h - Reorder all of the patches that used to follow this to precede.
