From 41d5734442c03439a534abfc2493d0ce9ca5000a Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 16 Feb 2025 12:12:40 +0100 Subject: lmb: move lmb_map_update_notify() to EFI When building with qemu_arm64_defconfig with CONFIG_CC_OPTIMIZE_FOR_DEBUG=y and CONFIG_EFI_LOADER=n an error undefined reference to efi_add_memory_map_pg occurs. Move the EFI dependent part of lmb_map_update_notify() to the EFI sub-system.
