Synchronous Exception at 0x00000000F6D72A64

[xianliang]

My board has something wrong with the UART port log as below:
Synchronous Exception at 0x00000000F6D72A64

then flash debug version BIOS to get more detail information as below:
Platform exception reporting:0000000000000000
ESR_EL3: 0000000086000210
ELR_EL3: 000000000001a568

Any one can help me to point out the potential root cause ?

I'm a hardware engineer, it's hard for me to figure out the log information.
