efi_loader: centralize messaging for efi_init_obj_list

2026-05-01T08:30:03Z

If efi_init_obj_list() fails we cannot use the UEFI sub-system. * Instead of having messages for this everywhere write an error message in efi_init_obj_list(). * Always use (ret != EFI_SUCCESS) when checking the return value of efi_init_obj_list(). * Remove the return code from the error message as it does not help users to understand which initialization went wrong.

efi_loader: Separate device path into its own header

2025-05-25T09:27:18Z

These functions are useful for the EFI app. As a first step towards making these available outside lib/efi_loader, create a separate header file and include it where needed. Add proper comments to the functions, since many are missing at present. Signed-off-by: Simon Glass Reviewed-by: Heinrich Schuchardt

efi_loader: bootbin: do not load an initrd if none is provided

2025-05-01T07:19:24Z

Do not try to create an initrd device path nor try to register an initrd with the EFI_LOAD_FILE2_PROTOCOL if none is provided. Handle initrd installation in efi_binary_run_dp with efi_install_initrd, imitating what is done for the fdt.

efi: Fix efiboot for payloads loaded from memory

2025-04-11T11:20:38Z

Calling bootefi on an address that was loaded from memory (e.g., cramfs or SPI flash via "sf read", etc.), currently results in the EFI binary not being able to access the EFI image device path. For example, iPXE would fail with an error "EFI could not get loaded image's device path: Error 0x7f39e082 (https://ipxe.org/7f39e082)". This is due to an incomplete special-case in efi_binary_run, where a new device path was created but not used in all required places. Fix the in-memory special case, set the "bootefi_device_path" to the generated "file_path". iPXE will now boot, and report the device path as "/MemoryMapped(0x0,0xSTART,0xLEN)" Signed-off-by: Christian Kohlschütter Reviewed-by: Heinrich Schuchardt

efi_loader: Pass in the required parameters from EFI bootmeth

Rather than setting up the global variables and then making the call, pass them into function directly. This cleans up the code and makes it all a bit easier to understand. Signed-off-by: Simon Glass
