# Component makefile for mbedtls

# mbedtls by default builds into 3 libraries not one. We just use one for now (doesn't make a huge difference when static linking)

# Config:
# We supply our own hand tweaked mbedtls/config.h in our 'include' dir, the rest of upstream mbedtls is not changed.

# these OBJS_xxx variables  are copied directly from mbedtls/mbedtls/Makefile,
# minus a few values (noted in comments)
#
# If updating to a future mbedtls version you can just copy these in.
