-Subject: [PATCH] mips: bcm47xx: allow retrieval of complete nvram contents
-
-Host platforms such as routers supported by OpenWrt can
-support NVRAM reading directly from internal NVRAM store.
-The brcmfmac for one requires the complete nvram contents
-to select what needs to be sent to wireless device.
