Mark Salter 0ceac9e094 efi/arm64: Fix fdt-related memory reservation ... Commit 86c8b27a01: "arm64: ignore DT memreserve entries when booting in UEFI mode prevents early_init_fdt_scan_reserved_mem() from being called for arm64 kernels booting via UEFI. This was done because the kernel will use the UEFI memory map to determine reserved memory regions. That approach has problems in that early_init_fdt_scan_reserved_mem() also reserves the FDT itself and any node-specific reserved memory. By chance of some kernel configs, the FDT may be overwritten before it can be unflattened and the kernel will fail to boot. More subtle problems will result if the FDT has node specific reserved memory which is not really reserved. This patch has the UEFI stub remove the memory reserve map entries from the FDT as it does with the memory nodes. This allows early_init_fdt_scan_reserved_mem() to be called unconditionally so that the other needed reservations are made.
