Subject: [PATCH v2 3/8] remoteproc: qcom: Update IMEM PIL info on load
Date: Thu, 26 Dec 2019 21:32:10 -0800	[thread overview]
Message-ID: <20191227053215.423811-4-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20191227053215.423811-1-bjorn.andersson@linaro.org>

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()
