# This makefile should be included by devices that use Trusty TEE
# to pull in a set of Trusty KeyMint specific modules.
#
# Allow KeyMint HAL service implementation selection at build time. This must be
# synchronized with the TA implementation included in Trusty. Possible values:
#
# - Rust implementation for Trusty VM (requires Trusty VM support):
#   export TRUSTY_KEYMINT_IMPL=rust
#   export TRUSTY_SYSTEM_VM=nonsecure
# - Rust implementation for Trusty TEE (no Trusty VM support):
#   export TRUSTY_KEYMINT_IMPL=rust
# - C++ implementation (default): (any other value or unset TRUSTY_KEYMINT_IMPL)
