-Subject: [PATCH] brcmfmac: add basic validation of shared RAM address
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-While experimenting with firmware loading I ended up in a state of
-firmware reporting shared RAM address 0x04000001. It was causing:
-[   94.448015] Unable to handle kernel paging request at virtual address cd680001
-due to reading out of the mapped memory.
-
-This patch adds some basic validation to avoid kernel crashes due to the
-unexpected firmware behavior.
