# glue to  build the bootloader project from the original project. It 
# basically runs Make in the src/ directory but it needs to zero some variables
# the ESP-IDF project.mk makefile exports first, to not let them interfere.

build system: Refactor component.mk to not need component_common.mk New makefile component_wrapper.mk allows some variables to be set before component.mk is evaluated. This properly fixes problems with sdkconfig being hard to access in all phases of the build. Including component_common.mk is no longer necessary and will print a deprecation warning for components which use it. 2016-11-09 21:20:55 -05:00			`$(BOOTLOADER_BIN): $(SDKCONFIG_MAKEFILE)`
