In some situation, like uuu, the current mmc device won't return the correct value. Avoid the NULL pointer in secure storage proxy which may cause panic. Change-Id: Ie24afc270fec0b0977dee71b7fc44fe94876e410 Signed-off-by: Haoran.Wang <elven.wang@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.
