Now that we switched to PrePeiCore, we can execute the firmware image in place, using a stack and temporary heap in non-secure SRAM. This allows us to query the secure firmware for the size and placement of DRAM, and also allows the use of capsules for firmware update. NOTE: this requires a matching change on the ARM Trusted Firmware side.
