armv7R: K3: j721e: Add support for boot device detection J721E allows for booting from primary or backup boot media. Both media can be chosen individually based on switch settings. ROM looks for a valid image in primary boot media, if not found then looks in backup boot media. In order to pass this boot media information to boot loader, ROM stores a value at a particular address. Add support for reading this information and determining the boot media correctly.

arm: mach-k3: j721e: Rename BOOT_DEVICE_USB to BOOT_DEVICE_DFU J721e does not support USB Host MSC boot, but only supports DFU boot. Since BOOT_DEVICE_USB is often used for host boot mode and BOOT_DEVICE_DFU is used for DFU boot, rename BOOT_DEVICE_USB macro to BOOT_DEVICE_DFU Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>

arm: mach-k3: j721e_init: Add support for backup boot modes When the boot of J721E devices using the primary bootmode (configured via device pins) fails a boot using the configured backup bootmode is attempted. To take advantage of the backup boot mode feature go ahead and add support to the J721E init code to determine whether the ROM code performed the boot using the primary or backup boot mode, and if booted from the backup boot mode, decode the bootmode settings into the appropriate U-Boot mode accordingly so that the boot can proceed.
