I'm still trying to understand all the details myself, but apparently our firmware and initrd need to fit within the first 512MB because of dram_base + SZ_512M. When we change "dram_base + SZ_512M" to "~0", everything works. -- Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
