Subject: [PATCH V2 0/4] Add new driver for WCSS secure PIL loading
- Secure PIL is signed, split firmware images which only TrustZone (TZ) can
authenticate and load. Linux kernel will send a request to TZ to
authenticate and load the PIL images.
- When secure PIL support was added to the existing wcss PIL driver
earlier in [2], Bjorn suggested not to overload the existing WCSS
rproc driver [2], instead post a new driver for secure PIL alone.
This series adds a new secure PIL driver for the same.
