Commit Message

Bjorn Andersson Dec. 27, 2019, 5:32 a.m. UTC
Update the PIL info region structure in IMEM with information about
where the firmware for various remoteprocs are loaded.

Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
---

Changes since v1:
- Squashed patches for the individual drivers into one
- Probe defer on qcom_pil_info_available()
