In order to boot over USB, the device tree needs to enable a few extra nodes in SPL. Since the USB driver has the ability to detect host/device, the dr_mode can be removed from the device tree since it needs to act as a device when booting and OTG is the default mode. Add USB boot support to spl_board_boot_device and enable the corresponding config options. Signed-off-by: Adam Ford <aford173@gmail.com> Reviewed-by: Fabio Estevam <festevam@denx.de> |
