2019-10-06efi: device path for nvmePatrick Wildt
This allows our EFI API to create a device path node for NVMe devices. It adds the necessary device path struct, uses the nvme namespace accessor to retrieve the id and eui64, and also provides support for the device path text protocol.

2019-09-09efi_loader: volume name in EFI_FILE_PROTOCOL.GetInfo()Heinrich Schuchardt
We cannot determine the volume name in U-Boot. Instead of providing a dummy volume name in case of EFI_FILE_SYSTEM_INFO and EFI_UNSUPPORTED in case of EFI_FILE_SYSTEM_VOLUME_LABEL consistently return an empty string. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-09efi_loader: EFI_FILE_PROTOCOL rev 2 stubHeinrich Schuchardt
The UEFI specification requires to implement version 2 of the EFI_FILE_PROTOCOL. Provide the missing functions as stubs. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-05efi_loader: correctly render CD-ROM device path nodesHeinrich Schuchardt
Correct the name of the partition size component in struct efi_device_path_cdrom_path. Render entry, start, and size when converting a CD-ROM device path node to text. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-05efi_loader: interrupts in simple network protocolHeinrich Schuchardt
GetStatus() must clear the interrupt status. Transmit() should set the TX interrupt. Receive() should clear the RX interrupt. Initialize() and Start() should clear the interrupt status. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-08-15efi_loader: EFI_PXE_BASE_CODE_PROTOCOL stubHeinrich Schuchardt
U-Boot implements the EFI_PXE_BASE_CODE_PROTOCOL because GRUB uses the mode information for booting via PXE. All function pointers in the protocol were NULL up to now which will cause immediate crashes when the services of the protocol are called. Create function stubs for all services of the protocol returning EFI_UNSUPPORTED. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-30efi_loader: definition of efi_virtual_address_map()Heinrich Schuchardt

2019-07-06efi_loader: bump UEFI specification number to 2.8Heinrich Schuchardt
We are implementing UEFI variable RuntimeServicesSupported and set the unimplemented runtime functions return EFI_UNSUPPORTED as described in UEFI specification 2.8.

2019-06-14efi_loader: add RuntimeServicesSupported variableAKASHI Takahiro

2019-05-19efi_loader: implement deprecated Unicode collation protocolHeinrich Schuchardt
In EFI 1.10 a version of the Unicode collation protocol using ISO 639-2 language codes existed. This protocol is not part of the UEFI specification any longer. Unfortunately it is required to run the UEFI Self Certification Test (SCT) II, version 2.6, 2017. So we implement it here for the sole purpose of running the SCT. It can be removed once a compliant SCT is available. The configuration option defaults to no. Signed-off-by: Rob Clark <robdclark@gmail.com> Most of Rob's original patch is already merged. Only the deprecated protocol is missing. Rebase it and make it configurable. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-04-23efi_loader: consistent naming of protocol GUIDsHeinrich Schuchardt
We should consistently use the same name for protocol GUIDs as defined in the UEFI specification. Not adhering to this rule has led to duplicate definitions for the EFI_LOADED_IMAGE_PROTOCOL_GUID. Adjust misnamed protocol GUIDs. Adjust the text for the graphics output protocol in the output of the `efidebug dh` command. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

Commit 393fccdf6c73 ("efi_loader: efi_guid_t must be 64-bit aligned") has changed the alignment of efi_guid_t. This changed the size of struct efi_configuration_table on 32-bit systems form 20 to 24 bytes. As an array of this type is pointed to by the system table this breaks compatibility with existing versions of GRUB and Linux. Let's get back the original size by using the attribute __packed.

Create the handle of loaded images and the EFI_LOADED_IMAGE_PROTOCOL inside efi_setup_loaded_image(). Do not use local variables.
