Subject[PATCH v2 3/8] remoteproc: qcom: Update IMEM PIL info on load
Date
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()
