# Default BUILD profile is release

#The top level makefile two kinds of sub modules. Ones which are supported by the 'build infrastructure' and which are not.
# i.e The modules which supports 'build infrastructure' are included in ti/build/component.mk and follow a standard set of conventions and targets.
# They can be built using ti/build/makefile. Many newer targets such as AM3/4/5/6/7 have their modules in this category.
# Those targets in this makefile has the 'buildinfra_' prefix in them.

# The non-build infrastructure modules are the ones which do not adhere to the ti/build/component.mk . They have custom makefiles which are either RTSC generated or custom written makefiles with custom targets & build options.
# Many legacy components for K1/K2 follow this methodology.
# Those non-build infrastructure targets in this makefile has 'non-buildinfra_' prefix in them.
