Support for extracting (from libteec), patching and compiling
optee_client/tee-supplicant by NuttX apps. Defaults to version
4.6.0 (same as the current libteec).
Enabled with:
CONFIG_OPTEE_SUPPLICANT=y
CONFIG_LIBTEEC=y
And the following for the nuttx kernel:
CONFIG_ALLOW_BSD_COMPONENTS=y
CONFIG_FS_ANONMAP=y
CONFIG_DEV_OPTEE_SMC=y
CONFIG_DEV_OPTEE_SUPPLICANT=y
The version of the supplicant needs to match the libteec version
since the patch to be applied might fail otherwise. If the versions
differ the build will be aborted.
