ARM: dts: stm32: Add DFU support for DHCOR recovery
This patch configures U-Boot SPL for DHCOR SoM to permit DFU upload of SPL and subsequent u-boot.itb for recovery or commissioning purposes. To start U-Boot on DHCOR based board, e.g. Avenger96, proceed as follows: - Install dfu-util on the host PC (in debian this is package 'dfu-util') - Power off the Avenger96 board. - Connect both USB-serial console and USB-OTG microB ports to host PC. - Switch Avenger96 to USB boot mode -- BOOT0..2 switches all set to 0. - Power on the Avenger96 board. - Verify using '$ dmesg' that a new device has been detected as follows: New USB device found, idVendor=0483, idProduct=df11, bcdDevice= 2.00 New USB device strings: Mfr=1, Product=2, SerialNumber=3 Product: DFU in HS Mode @Device ID /0x500, @Revision ID /0x0000 Manufacturer: STMicroelectronics - Upload U-Boot SPL: $ dfu-util -a 1 -D u-boot-spl.stm32 - Upload U-Boot proper: $ dfu-util -a 0 -D u-boot.itb - At this point, SPL will wait for user to press "Ctrl-C" on serial console. When ready to interact with U-Boot, press Ctrl-C to start the bootloader.
