We want to add spi driver into u-boot to bring up with spi nor flash on imx28.
Could you please share us the patch especially with mxs_spi.c?
We meet the following issue when we use a old mxs_spi.c.
spi_flash_probe bus =2, cs =0, spi mode =3
spi_setup_slave: bus=2, cs=0, max_hz=20000000, mode=3
MXS SPI: Timeout waiting for data
Error: spi_nor_flash_query(): 0x00:0x00:0x00
SF: Failed to read the ID codes
