From: Simon Glass <sjg@chromium.org> This series improves U-Boot's EFI app support and adds new functionality for managing devicetree reserved-memory regions. The main focus is on enhancing memory management when running as an EFI application. A new mechanism is introduced to sync EFI reserved-memory regions (such as runtime services and ACPI tables) with the devicetree's /reserved-memory nodes. This ensures that Linux doesn't inadvertently use memory regions that EFI firmware has reserved. The main improvements are: - New 'fdt reserved' command to display devicetree reserved-memory regions - New 'efi memsync' command to synchronize EFI memory map with devicetree - Enhance EFI application support with better memory region handling - Improve EFI debugging commands and device path handling - Better integrate EFI boot services and devicetree setup There are a few other minor thigns: - Enhance efidebug commands with media device and driver information - Expose EFI device-paths in a few places in bootstd - Improve bootflow device reporting - ARM-specific fixes for exception level handling This series addresses many of the issues found in booting Linux on Qualcomm X-Elite laptops using the EFI app. Simon Glass (20): efi: Set the efi_media device name when binding efi: app: Avoid switching exception levels on ARM efi: app: Avoid freeing memory on exit efi: Add a way to show media devices efi: Add all messaging types for device paths efi: Convert a device-path to a uclass and name efi: Add a uclass column to efidebug media command efi: Implement efidebug show drivers in the app boot: Correct filename in bootmeth_common_read_file() boot: Show the device path for EFI bootflows boot: Show the underlying bootflow device in the app efi: Use abuf when reading EFI variables efi: Add a command to help with shim efi: Add an efi subcommand to show the loaded image fdt: Add a function to show the reserved-memory nodes fdt: Add a command to show reserved-memory regions efi: Provide a way to sync EFI reserved-memory to fdt fdt: Provide a command to sync the reserve-memory node efi: app: Add a simple-framebuffer node if enabled efi: app: Sync EFI reserved-memory to the devicetree boot/bootmeth-uclass.c | 2 +- boot/fdt_support.c | 54 ++++++++ cmd/Kconfig | 9 ++ cmd/Makefile | 1 + cmd/bootflow.c | 38 +++++- cmd/efi.c | 37 ++++- cmd/efidebug.c | 73 +++++++--- cmd/fdt.c | 7 +- cmd/nvedit_efi.c | 62 ++++++--- cmd/shim.c | 65 +++++++++ doc/usage/cmd/efi.rst | 50 +++++++ doc/usage/cmd/efidebug.rst | 24 +++- doc/usage/cmd/fdt.rst | 26 ++++ doc/usage/cmd/shim.rst | 101 ++++++++++++++ doc/usage/index.rst | 1 + include/efi.h | 51 +++++++ include/efi_api.h | 20 ++- include/efi_device_path.h | 25 ++++ include/fdt_support.h | 7 + include/shim.h | 13 ++ lib/efi/device_path.c | 125 +++++++++++++++++ lib/efi_client/app_run.c | 21 ++- lib/efi_client/efi.c | 249 +++++++++++++++++++++++++++++++++- lib/efi_client/efi_app.c | 12 +- lib/efi_client/efi_app_init.c | 21 ++- test/cmd/fdt.c | 40 ++++++ 26 files changed, 1072 insertions(+), 62 deletions(-) create mode 100644 cmd/shim.c create mode 100644 doc/usage/cmd/shim.rst create mode 100644 include/shim.h -- 2.43.0 base-commit: 88123cd086d8999443f84e8311913b7e94b6aa9b branch: apb
