[U-Boot] [PATCH 2/2] spi: add common spi3 controller driver

Scott Jiang scott.jiang.linux at gmail.com
Thu Sep 25 11:25:30 CEST 2014


SPI3 controller is not only used on BF609 platform. So we add a common controller
driver and leave machine specific configuration in board drivers.
Remove obsolete spi6xx.h and select new board driver in configuration file.
