bcma: Move initialization of SPROM to prevent overwrite
The first thing bcm47xx_fill_sprom does is initialize (zero fill) the SPROM. For BCMA SOC, this wipes out any values previously read by bcm47xx_fill_sprom_ethernet (see arch/mips/bcm47xx/setup.c - bcm47xx_get_sprom_bcma). Move the initialization of SPROM so it is called prior to filling in any values. Signed-off-by: Nathan Hintz <nlhintz@hotmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
