+Subject: [PATCH] brcmfmac43455-sdio.txt: Follow raspbian change for
+ boardflags3
+
+Without this change the WiFi interface on RPi4 never comes up. Also the
+upstream repository doesn't include this change. It is only (as far as I
+know) part of the raspberrypi deb repository with the following
+changelog:
+
+firmware-nonfree (1:20190114-1+rpt2) buster; urgency=medium
+  * Update brcmfmac43455-sdio.txt
+    - Update boardflags3

+    # SRCTREECOVEREDTASKS, which don't get run because they affect the source
+    # tree and, when using devtool, we want the developer's changes to be the
+    # single source of truth. kernel-yocto.bbclass adds do_kernel_configme to
+    # SRCTREECOVEREDTASKS, so it doesn't run in a devtool build., In a normal
+    # non-devtool build, do_kernel_configme creates ${B}.config.
+    #
+    # - Normally (e.g. in linux-yocto), it would be OK that do_kernel_configme
+    # doesn't run, because the first few lines of do_configure in kernel.bbclass
+    # populate ${B}.config from either ${S}.config (if it exists) for custom
+    # developer changes, or otherwise from ${WORDIR}/defconfig.
+    #
+    # - In linux-raspberrypi, we add do_configure_prepend, which tweaks
+    # ${B}.config. Since this runs *before* the kernel.bbclass do_configure,
+    # ${B}.config doesn't yet exist and we hit an error. Thus we need to move
+    # the logic from do_configure up to before our do_configure_prepend. Because
