17// We check in the prebuilt nanopb protobuf file under the current folder
18// because the compile tool chain using trusty/user/base/make/compile_proto.mk
19// might not work under certain environment with lower version of python
20// protobuf installed. You need to generate and check in the new protobuf file
21// if you change this file in order for the change to take effect!
22//
23// To generate the file using the tool chain in trusty tree, add the following
24// command to rules.mk:
25//
26// PB_GEN_DIR := [Your generation folder]
27// include trusty/user/base/make/compile_proto.mk
28// $(eval $(call compile_proto,$(KEYMASTER_DIR)/keymaster_attributes.proto,$(PB_GEN_DIR)))
29//
30// The generated .pb.c and .pb.h file would be under PB_GEN_DIR, include them
31// to the source path.
32//
33// To generate the file using your own tool chain, please follow the guide at
34// https://github.com/nanopb/nanopb.
35// Please check the nanopb version in trusty tree at external/nanopb-c to make
36// sure you are using the same nanopb version.
