-From fdd0bd88ceaecf729db103ac8836af5805dd2dc1 Mon Sep 17 00:00:00 2001

-Subject: [PATCH] brcmfmac: add CLM download support
-
-The firmware for brcmfmac devices includes information regarding
-regulatory constraints. For certain devices this information is kept
-separately in a binary form that needs to be downloaded to the device.
-This patch adds support to download this so-called CLM blob file. It
-uses the same naming scheme as the other firmware files with extension
-of .clm_blob.
-
-The CLM blob file is optional. If the file does not exist, the download
-process will be bypassed. It will not affect the driver loading.
