efi_loader: EFI_DEVICE_PATH_UTILITIES_PROTOCOL configurable

2021-01-20T07:17:17+00:00

Allow the EFI_DEVICE_PATH_UTILITIES_PROTOCOL to be disabled via
configuration.

On systems that are very tight on U-Boot image size we may want to disable
the protocol. As it is required to run the UEFI Shell enable it by default.

efi_loader: make the UEFI boot manager configurable

2021-01-20T07:09:34+00:00

Some boards are very tight on the binary size. Booting via UEFI is possible
without using the boot manager.

Provide a configuration option to make the boot manager available.

efi_loader: move load options to new module

2021-01-19T17:56:08+00:00

Move all load options related functions to a new module. So that they can
be compiled independently.

efi_loader: implement EFI_DT_FIXUP_PROTOCOL

2021-01-13T01:38:01+00:00

A boot manager like GRUB can use the protocol to

* apply U-Boot's fix-ups to the a device-tree
* let U-Boot make memory reservations according to the device-tree
* install the device-tree as a configuration table

efi_loader: remove EFI_HII_CONFIG_ROUTING_PROTOCOL

2020-12-10T08:15:32+00:00

Our implementation of the EFI_HII_CONFIG_ROUTING_PROTOCOL is a mere stub,
where all services return an error code. The protocol is neither needed for
the EFI shell nor for the UEFI SCT. To reduce the code size remove it from
the U-Boot binary.

efi_loader: add firmware management protocol for raw image

2020-12-03T20:22:50+00:00

In this commit, a very simple firmware management protocol driver
is implemented. It will take a binary image in a capsule file and
apply the data using dfu backend storage drivers via dfu_write_by_alt()
interface.

So "dfu_alt_info" variable should be properly set to specify a device
and location to be updated. Please read README.dfu.

efi_loader: add firmware management protocol for FIT image

2020-12-03T20:22:50+00:00

In this commit, a very simple firmware management protocol driver
is implemented. It will take a common FIT image firmware in a capsule
file and apply the data using dfu backend storage drivers via
update_fit() interface.

So "dfu_alt_info" variable should be properly set to specify a device
and location to be updated. Please read README.dfu.

Fit image is a common file format for firmware update on U-Boot, and
this protocol works neatly just as a wrapper for one.

efi_loader: define UpdateCapsule api

2020-12-03T20:22:49+00:00

In this commit, skeleton functions for capsule-related API's are
added under CONFIG_EFI_UPDATE_CAPSULE configuration.
Detailed implementation for a specific capsule type will be added
in the succeeding patches.

efi_loader: Add basic EFI_TCG2_PROTOCOL support

2020-11-14T04:05:46+00:00

Since U-boot EFI implementation is getting richer it makes sense to
add support for EFI_TCG2_PROTOCOL taking advantage of any hardware TPM
available on the device.

This is the initial implementation of the protocol which only adds
support for GetCapability(). It's limited in the newer and safer
TPMv2 devices.

efi_loader: add efi_create_indexed_name()

2020-10-30T13:27:43+00:00

This function will be used from several places in UEFI subsystem
to generate some specific form of utf-16 variable name.
For example, L"Capsule0001"

Signed-off-by: AKASHI Takahiro 
Move function to separate module.
Use char * as argument instead of u16 *.
