It seems that despite NSS not being supported in OpenWrt the memory it usually uses needs to be reserved anyway for stability reasons. Link: https://github.com/openwrt/openwrt/pull/16928 Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH 11/19] soc: qcom: fix smp2p ack on ipq6018
|
|
|
|
IPQ6018 seem to need different ack mechanism for smp2p messaging. This
|
|
fixes q6v5_wcss remoteproc firmware reloading. Without this first load
|
|
is OK, but subsequent loads would hang and fail to complete.
