This is a demo that CM4 will boot up by u-boot without typing any command. It boots up at u-boot early init, try to minimize the time from power up to the CM4 running. Since CM4 runs on QSPI NOR XIP, we have to disable the QSPI driver in u-boot to avoid conflict. RDC for shared GPIO1 is added, but not enabled, because the kernel is not ready for shared GPIO1. Users can uncomment the CONFIG_IMX_RDC to enable it. Some legacy codes in mx6sxsabreauto are removed. We only need this work on mx6sxsabresd as a demo. Signed-off-by: Ye Li <ye.li@nxp.com>
