A limitation of the EFI loader at present is that it does not build with sandbox. This makes it hard to write tests, since sandbox is used for most testing in U-Boot.
This series enables the EFI loader feature. It allows sandbox to build and run a trivial function which calls the EFI API to output a message.
Also included in v8 is support for running the full EFI self tests. These run OK with some tweaks to a few parts of the code.
This series is at u-boot-dm/efi-working
Changes in v8: - Expand series substantially to support bootefi selftest - Rebase to master
Changes in v7: - Drop an unnecessary comment - Drop patch "efi: Init the 'rows' and 'cols' variables" - Drop patches previous applied - Move some of the code from efi_memory_init() into a separate function - Update patch subject s/builder/build/
Changes in v6: - Warn about building sandbox EFI support on something other than __x86_64__
Changes in v5: - Add new patch to disallow CMD_BOOTEFI_SELFTEST on sandbox - Drop call to efi_init_obj_list() which is now done in do_bootefi() - Introduce load_options_path to specifyc U-Boot env var for load_options_path - Rebase to master
Changes in v4: - Rebase to master - Update SPDX tags
Changes in v3: - Add new patch to rename bootefi_test_finish() to bootefi_run_finish() - Add new patch to split out test init/uninit into functions - Add patch to create a function to set up for running EFI code - Drop incorrect map_sysmem() in write_smbios_table() - Init the 'rows' and 'cols' vars to avoid a compiler error (gcc 4.8.4) - Rebase to master
Changes in v2: - Rebase to master - Update to use mapmem instead of a cast
