- 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.
