Logically, the current update_tftp() should and does compile and work correctly even without satisfying the following condition:

#if defined(CONFIG_UPDATE_TFTP) && !defined(CONFIG_MTD_NOR_FLASH) #error "CONFIG_UPDATE_TFTP and !CONFIG_MTD_NOR_FLASH needed for legacy behaviour" #endif

It would be better to just drop it so that this function will be used on wider range of platforms.

This function is essentially independent from tffp, and will also be utilised in implementing UEFI capsule update in a later commit. So just give it a more generic name. In addition, a new configuration option, CONFIG_DFU_ALT, was introduced so that the file will be compiled with different options, particularly one added in a later commit.

The main purpose of this patch is to separate a generic interface for updating firmware using DFU drivers from "auto-update" via tftp.

This function will also be used in implementing UEFI capsule update in a later commit.

If this option, CONFIG_EFI_SETUP_EARLY, is enabled, the initialisation of UEFI subsystem will be done as part of U-Boot initialisation.

Please note that this option won't be enabled explicitly by users, instead, should be enabled implicitly by other configuration options.

Specifically, this feature will be utilised in implementing capsule-on-disk feature.

Capsule data can be loaded into the system either via UpdateCapsule runtime service or files on a file system (of boot device). The latter case is called "capsules on disk", and actual updates will take place at the next boot time.

In this commit, we will support capsule on disk mechanism.

Please note that U-Boot itself has no notion of "boot device" and all the capsule files to be executed will be detected only if they are located in a specific directory, \EFI\UpdateCapsule, on a device that is identified as a boot device by "BootXXXX" variables.

A capsule tagged with the guid, EFI_FIRMWARE_MANAGEMENT_CAPSULE_ID_GUID, is handled as a firmware update object. What efi_update_capsule() basically does is to load any firmware management protocol (or fmp) drivers contained in a capsule, find out an appropriate fmp driver and then invoke its set_image() interface against each binary in a capsule. In this commit, however, loading drivers is not supported.

The result of applying a capsule is set to be stored in "CapsuleXXXX" variable, but its implementation is deferred to a fmp driver.

In this commit, a very simple firmware management protocol driver is implemented. It will take a binary image in a capsule file and apply the data using dfu backend storage drivers via dfu_write_by_alt() interface.

So "dfu_alt_info" variable should be properly set to specify a device and location to be updated. Please read README.dfu.

The test can run on sandbox build and it attempts to execute a firmware update via a capsule-on-disk, using a FIT image capsule, CONFIG_EFI_CAPSULE_FIT.

To run this test successfully, you need configure U-Boot specifically; See test_capsule_firmware.py for requirements, and hence it won't run on Travis CI.
