From fa4f3e5338b0fc2fc19b7794e11b344392569d57 Mon Sep 17 00:00:00 2001 From: Ben Greear Date: Tue, 29 Sep 2020 20:15:29 +0300 Subject: [PATCH] ath11k: support loading ELF board files The QCA6390 board I have, model 8291M-PR comes with an ELF board file. To get this to at least somewhat work, I renamed bdwlan.e04 to 'board.bin' and then added this patch to check for ELF magic string in the beginning of the file. If that is found, use type ELF. After this the driver loads.
