-Subject: [PATCH] brcmfmac: Add support for multiple PCIE devices in
- nvram.
-
-With PCIE it is possible to support multiple devices with the
-same device type. They all load the same nvram file. In order to
-support this the nvram can specify which part of the nvram is
-for which pcie device. This patch adds support for these new
-types of nvram files.
