This patch adds a driver for Freescale Colfire Queued SPI bus. Coded to work with 8 bits per transfer to use with SPI flash. CPOL, CPHA, and CS_ACTIVE_HIGH can be configured. Tested with MCF5270 which have 4 chip selects. Activate by #define CONFIG_CF_QSPI in board config. Signed-off-by: Richard Retanubun <richardretanubun@ruggedcom.com> |
