I checked this web and I had some questions want to ask:
(1) Is this Appendix only based on using ATF (Arm Trusted Firmware) as the Secure Monitor or not? Because EL3 is only generated by building Arm Trusted Firmware.
(2) If I want to use U-Boot as the Secure Monitor (non-ATF way) to control UART1 on L4 Slave Peripheral Bus, I know I can manage/configure secure L3 or L4 registers in "u-boot.scr" file. So how many and what kind of registers should I manage/configure to achieve my goal?
