efi: device path for nvme

2019-10-06T14:02:37+00:00

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.

efi_loader: volume name in EFI_FILE_PROTOCOL.GetInfo()

2019-09-09T13:21:09+00:00

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.

efi_loader: correctly render CD-ROM device path nodes

2019-09-05T21:18:51+00:00

Correct the name of the partition size component in struct

Render entry, start, and size when converting a CD-ROM device path node to
text.

efi_loader: interrupts in simple network protocol

2019-09-05T21:18:51+00:00

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.

efi_loader: EFI_PXE_BASE_CODE_PROTOCOL stub

2019-08-15T18:33:10+00:00

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.

efi_loader: definition of efi_virtual_address_map()

2019-07-30T19:36:22+00:00

Use efi_uintn_t where the UEFI spec uses UINTN. Use efi_uintn_t also for
the result of the division of two efi_uintn_t.

efi_loader: bump UEFI specification number to 2.8

2019-07-06T19:25:32+00:00

We are implementing UEFI variable RuntimeServicesSupported and set the
unimplemented runtime functions return EFI_UNSUPPORTED as described in UEFI
specification 2.8. So let's also advertise this specification version in
our system table.

efi_loader: correct signature of ConvertPointer()

2019-06-29T02:24:35+00:00

ConvertPointer() must be EFIAPI. The first parameter should be of type
efi_uint_t. Use the same parameter name as the UEFI specification.

pointer.
