Trouble booting to UEFI

I recently purchased the board standalone rather than the whole system, and have not been able to progress through to UEFI. Below are the outputs from each console. I had to update the SCP to upstream as the factory build, and the updated 20180226-LB1.1-ACPI-ramfw.bin did not support my DRAM. I’ve tried various snapshots from linaro.org as well as building arm trusted firmware, and UEFI from source, but this is as far as it ever gets.

Output from LPUART console
