[TF-A] Spurious interrupt 1023

I asked a similar question before, but I have since made some headway concerning routing fiq interrupts to EL3. I placed an HS_DEBUG command to print the ID, which returns 1023. The RX signal on one of the attached UARTs causes a solid red light and the debug message continuously loops. When I use the functions from gicv2.h, I receive an assertion error regarding MAX_SPI_ID, but the looping stops.

I think the 1023 ID suggests non-secure is receiving a secure interrupt OR I’m dealing with a possible race condition. Any thoughts? Should I attach my code?
