RPMB storage proxy service will return fail if the rpmb key is not correct, we should not return early here if the rpmb key has not been set because we still need to initialize the hwcrypto service to generate the rpmb key blob. This commit also adds more hint when set the rpmb key. Change-Id: I8ee59e4e277b545283d63b1070e671d508dbe0c2 Signed-off-by: Luo Ji <ji.luo@nxp.com> |

Queueless Trusty IPC
ql-tipc is a portable client library that implements Trusty queueless IPC. It is intended to enable Trusty IPC in bootloader environments.
Code organization
IPC components
- libtipc - Functions to be called by library user
- ipc - IPC library
- ipc_dev - Helper functions for sending requests to the secure OS
- rpmb_proxy - Handles RPMB requests from secure storage service
- avb - Sends requests to the Android Verified Boot service
Misc
- examples/ - Implementations of bootloader-specific code.
- arch/$ARCH/ - Architecture dependent implementation of Trusty device (see trusty_dev.h). Implements SMCs on ARM for example.
Portability Notes
The suggested approach to porting ql-tipc is to copy all header and C files into the bootloader and integrate as needed. RPMB storage operations and functions defined in trusty/sysdeps.h require system dependent implementations.
If the TIPC_ENABLE_DEBUG preprocessor symbol is set, the code will include debug information and run-time checks. Production builds should not use this.
