efi_loader: new functions to print loaded image information

2018-04-05T13:23:55+00:00

Introduce functions to print information about loaded images.

If we want to analyze an exception in an EFI image we need the offset
between the PC and the start of the loaded image.

With efi_print_image_info() we can print the necessary information for a
single image, e.g.

UEFI image [0xbffe6000:0xbffe631f] pc=0x138 '/\snp.efi'

efi_print_image_infos() provides output for all loaded images.

efi_loader: implement EFI_FILE_SYSTEM_INFO

2018-04-05T08:01:45+00:00

Implement the information type EFI_FILE_SYSTEM_INFO in the service
GetInfo() of the EFI_FILE_PROTOCOL.

The volume label is not available in U-Boot. As a work-around use the
partition name instead.

efi_loader: implement event groups

2018-04-04T09:00:07+00:00

If an event of a group event is signaled all other events of the same
group are signaled too.

Function efi_signal_event is renamed to efi_queue_event.
A new function efi_signal_event is introduced that checks if an event
belongs to a group and than signals all events of the group.
Event group notifciation is implemented for ExitBootServices,
InstallConfigurationTable, and ResetSystem.

2018-04-04T09:00:06+00:00

Event groups are used to signal multiple events at the same time.
They are identified by GUIDs. This patch provided the predefined
GUIDs of UEFI specification 2.7.

efi_loader: manage events in a linked list

2018-04-04T09:00:06+00:00

Lift the limit on the number of events by using a linked list.

This also allows to have events with type == 0.

This patch is based on Rob's patch

2018-04-04T09:00:06+00:00

The second argument of the bootefi command should always be usable to
specify a device tree. This was missing for bootefi selftest and
bootefi hello.

Proper error handling is added.
