So far NuttX has supported OP-TEE interfacing over local and RPMsg sockets. This commit introduces support for direct invocation of OP-TEE through arm SMCs. The SMC transport is enabled through CONFIG_DEV_OPTEE_SMC. This SMC implementation has been tested only with arm64, OP-TEE rev 4.4. Note that it does not support reverse direction RPCs, i.e. from the Secure World to the Normal World to something like optee supplicant. A basic RPC handling skeleton is provided with implementation for some basic functions (alloc/free mem, and foreign interrupts) but no supplicant command handling. (+one minor change s/parm/param in arch/arm64/include/syscall to satisfy the spellchecker during PR) Signed-off-by: George Poulios <gpoulios@census-labs.com> |
