[U-Boot] [PATCH v8 00/30] efi: Enable sandbox support for EFI loader

[Simon Glass]

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
