   4 Subject: [PATCH 02/15] bcm47xx: move the nvram header file into common space
   5
   6 Moving mach-bcm47xx/bcm47xx_nvram.h makes it possible to reuse this
   7 header on the arm bcm47xx (BCM5301X) devices. This way a driver gets
   8 the correct functions to access the nvram depending on the SoC it boots
   9 for.
