- * This test checks the FileLoad2 protocol.
- * A known file is read from the file system and verified.
- *
- * An example usage - given a file image with a file system in partition 1
- * holding file initrd - is:
- *
- * * Configure the sandbox with
- *
- * CONFIG_EFI_SELFTEST=y
- * CONFIG_EFI_LOAD_FILE2_INITRD=y
- * CONFIG_EFI_INITRD_FILESPEC="host 0:1 initrd"
- *
- * * Run ./u-boot and execute
- *
- * host bind 0 image
- * setenv efi_selftest load initrd
- * bootefi selftest
- *
- * This would provide a test output like:
- *
- * Testing EFI API implementation
- *
- * Selected test: 'load initrd'
- *
- * Setting up 'load initrd'
- * Setting up 'load initrd' succeeded
- *
- * Executing 'load initrd'
- * Loaded 12378613 bytes
- * CRC32 2997478465
- *
- * Now the size and CRC32 can be compared to the provided file.
