Qualcomm SOCs have a secure remote processor that provides secure
execution environment for processing sensitive data and also performs
cryptographic operations using protected keys stored in its secure
storage. This patch series introduces a Peripheral Authentication
based remoteproc driver that handles booting, shutdown and crash
scenarios for SPSS. Also this driver can handle late attach usecase
where remote processor is already booted even before linux. This
patchset builds up on the skip firmware load patch
"remoteproc: add support to skip firmware load when recovery" which is
in review.
