- Subject: [PATCH 03/17] bcm47xx-sprom: add Broadcom sprom parser driver
- This driver needs an nvram driver and fetches the sprom values from the
- nvram and provides it to any other driver. The calibration data for the
- wifi chip the mac address and some more board description data is
- stores in the sprom.
- This is based on a copy of arch/mips/bcm47xx/sprom.c and my plan is to
- make the bcm47xx MIPS SoCs also use this driver some time later.
