* efi_loader: output load options in helloworldHeinrich Schuchardt2017-12-011-2/+35
| | | | | | | | | | | | We need to test if we pass a valid image handle when loading and EFI application. This cannot be done in efi_selftest as it is not loaded as an image. So let's enhance helloworld a bit. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

* efi_loader: fix efi_convert_device_node_to_textHeinrich Schuchardt2017-12-011-66/+88
| | | | | | | | | | | | | | | | | | | | | | | | | We need to implement to different functions for the EFI_DEVICE_PATH_TO_TEXT_PROTOCOL: ConvertDeviceNodeToText ConvertDevicePathToText A recent patch screwed up efi_convert_device_node_to_text to expect a device path and not a node. The patch makes both service functions work again. efi_convert_device_node_to_text is renamed to efi_convert_single_device_node_to_text and efi_convert_device_node_to_text_ext is renamed to efi_convert_device_node_to_text to avoid future confusion.

* efi_loader: initialise partition_signature memoryJonathan Gray2017-12-011-2/+19
| | | | | | | | | | | | | | | | | | | | | Zero partition_signature in the efi_device_path_hard_drive_path structure when signature_type is 0 (no signature) as required by the UEFI specification. This is required so that efi_dp_match() will work as expected when doing memcmp() comparisons. Previously uninitialised memory would cause it not match nodes when it should have when the signature type was not GUID.

| | | | | | | | | | | | | | | | | | | With the introduction of EFI variable support, we also wanted to persist these EFI variables. However, the way it was implemented we ended up persisting all U-Boot environment variables on every EFI boot. That could potentially lead to unexpected side effects because variables that were not supposed to be written to persisted env get written. It also means we may end up writing the environment more often than we should. For this release, let's just disable EFI variable persistence and instead implement it properly for the next one.
