Resolved! When updating from arm-trusted-firmware-v2.4-stm32mp-r1 to arm-trusted-firmware-v2.4-stm32mp-r2 I get PANIC on UART

I didn't change anything in the device tree just compiled the arm-trusted-firmware-v2.4-stm32mp-r2 instead of arm-trusted-firmware-v2.4-stm32mp-r1 and I get the following on UART:PANIC at PC : 0x2ffcfd2bWhat is different between the two versions?
