Load and Run U-Boot on keystone EVMs using UART download
========================================================
Open BMC and regular UART terminals.
1. On the regular UART port start xmodem transfer of the u-boot.bin
2. Using BMC terminal set the ARM-UART bootmode and reboot the EVM
BMC> bootmode #4
MBC> reboot
3. When xmodem is complete you should see the u-boot starts on the UART port
