Subject[PATCH v6 3/5] remoteproc: qcom: Update PIL relocation info on load
Date
Update the PIL relocation information in IMEM with information about
where the firmware for various remoteprocs are loaded.

Reviewed-by: Vinod Koul <vkoul@kernel.org>
Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
---

Changes since v5:
- Added select QCOM_PIL_INFO to all relevant Kconfig options
- Replaced mem_reloc with mem_phys, to get the start of the memory region,
rather than the bottom address prior to relocation.
- Include qcom_pil_info.h in qcom_q6v5_wcss.c
