Give more flexibility to define configs that can be interpreted by make, e.g. to define fallback values of configs like in the example below.
Before this change, the config lines: #define CONFIG_SPL_MAX_SIZE 2048 #define CONFIG_SPL_PAD_TO CONFIG_SPL_MAX_SIZE would have been changed in autoconfig.mk into: CONFIG_SPL_MAX_SIZE=2048 CONFIG_SPL_PAD_TO="CONFIG_SPL_MAX_SIZE" Hence, a make recipe using as an argument to $(OBJCOPY): --pad-to=$(CONFIG_SPL_PAD_TO) would have issued: --pad-to="CONFIG_SPL_MAX_SIZE" which means nothing for $(OBJCOPY) and makes it fail. Thanks to this change, the config lines above are changed in autoconfig.mk into: CONFIG_SPL_MAX_SIZE=2048 CONFIG_SPL_PAD_TO=$(CONFIG_SPL_MAX_SIZE) Hence, the make recipe above now issues: --pad-to=2048 as expected from the defined config.
