How to enable the UART1 in ATF (Arm Trusted Firmware) when you configure the U-Boot to use UART1?

Environment

    Intel® Quartus® Prime Pro Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem in the Arm Trusted Firmware (ATF) version 2.4.0 and earlier, when uart1 is configured for U-boot, the HPS will hang.

Resolution

To work around this problem in the ATF version 2.4.0 and eariler, you could make a modification to use the real register address for UART1 in arm-trusted-frimware/plat/intel/soc/common/include/platform_def.h.

Here is an example for Agilex™ SoC devices (macro PLAT_UART0_BASE used across the ATF code, a simple modification is suggested here):

Change 

#define PLAT_UART0_BASE (0xFFC02000)

to 

#define PLAT_UART0_BASE (0xFFC02100)
