efi_loader: Support loading a ramdisk with bootefi

2025-08-08T06:45:18+00:00

It is sometimes useful to be able to boot via EFI using a Linux initrd.
Add support for this.

Fix a 'specifiy' typo while here.

efi_loader: Separate device path into its own header

2025-05-25T09:27:18+00:00

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.

efi_selftest: use do_bootefi_exec()

2025-04-19T10:47:33+00:00

The EFI selftest should match executing a real EFI binary
as closely as possible.

Use do_bootefi_exec() to enter the EFI selftest.

efi_loader: superfluous efi_restore_gd after EFI_CALL

2024-05-01T05:37:32+00:00

EFI_CALL() invokes __efi_entry_check() which executes set_gd(efi_gd).
There is no need to execute set_gd(efi_gd) again via efi_restore_gd().

cmd: bootefi: error handling bootefi selftest

2024-03-21T06:28:43+00:00

If bootefi selftest is executed and a problem with the device-tree
installation occurs, efi_install_fdt() writes sensible error messages.
It never returns EFI_INVALID_PARAMETER. It neither makes sense to check
for EFI_INVALID_PARAMETER nor to show the usage help for the bootefi
command in this case.

cmd: bootefi: Don't show usage help if EFI binary fails.

2024-03-21T06:28:43+00:00

If an EFI binary returns an error code EFI_INVALID_PARAMETER, we show the
usage help for the bootefi command:

    Shell> exit 0x8000000000000002
    ## Application failed, r = 2
    bootefi - Boots an EFI payload from memory

    Usage:
    bootefi [:] []
      - boot EFI payload
    bootefi bootmgr [fdt address]
      - load and boot EFI payload based on BootOrder/BootXXXX variables.

        If specified, the device tree located at  gets
        exposed as EFI configuration table.

This makes no sense.

cmd: bootefi: move library interfaces under lib/efi_loader

2023-12-17T12:04:54+00:00

In the prior commits, interfaces for executing EFI binary and boot manager
were carved out. Move them under efi_loader directory so that they can
be called from other places without depending on bootefi command.

Only efi_selftest-related code will be left in bootefi.c.

cmd: bootefi: localize global device paths for efi_selftest

2023-12-17T12:04:54+00:00

Device paths allocated in bootefi_test_prepare() will be immediately
consumed by do_efi_selftest() and there is no need to keep them for later
use. Introduce test-specific varialbles to make it easier to move other
bootmgr functions into library directory in the next commit.
