From 35f28f2838948e33f46c60b966a48a7e78ae8743 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Tue, 13 Dec 2022 23:55:26 +0100 Subject: mac80211: add ath11k AHB support This is the follow up to the PCI support commit now providing support for AHB variant as well, though currently only for ipq807x as that is only OpenWrt supported SoC ath11k supports as well. Currently, we are disabling coldboot calibration on ipq807x as it does not work, there is a remoteproc bug that makes it come late out of reset so disable coldboot until that is fixed. Also, as ath11k is quite memory hungry, we are introducing a config option to use the limits for 512MB of RAM, similar to what QCA does downstream but in way simpler and cleaner way so that 512MB save some RAM. 512MB profile is also set as the default for now.
