efi_loader: expose protocols via GUID

2017-07-25T08:58:07+00:00

shim.efi (or rather gnu-efi's LibLocateProtocol() which shim.efi uses)
resolves protocols via efi_locate_handle() so the console protocols
need to be added to the efi object list.

efi_loader: parameter types for CreateEvent, SetTimer

2017-07-24T12:54:29+00:00

The first argument 'type' of CreateEvent is an 32bit unsigned
integer bitmap and not an enum.

The second argument 'type' of SetTimer take values of an
enum which is called EFI_TIMER_DELAY in the UEFI standard.
To avoid confusion rename efi_event_type to efi_timer_delay.

efi_loader: correct size for tpl level

2017-07-19T12:31:04+00:00

The UEFI standard defines the type for the tpl level as EFI_TPL
alias UINTN.

UINTN is an integer is defined as an unsigned integer of native
width. So we can use size_t for the definition.

efi_loader: implement multiple event support

2017-07-19T12:26:09+00:00

Up to now the boot time supported only a single event.
This patch now allows four events.

efi_loader: use struct efi_event * instead of void *

2017-07-19T12:26:01+00:00

In our implementation the internal structure of events is known.
So use the known type instead of void.

efi_loader: implement EFI_DEVICE_PATH_TO_TEXT_PROTOCOL

2017-07-19T12:14:40+00:00

ConvertPathToText is implemented for
* type 4    - media device path
* subtype 4 - file path

This is the kind of device path we hand out for block devices.

All other cases may be implemented later.

efi_loader: implement InstallProtocolInterface

2017-07-19T12:14:38+00:00

efi_install_protocol_interface up to now only returned an error code.

The patch implements the UEFI specification for InstallProtocolInterface
with the exception that it will not create new handles.

efi_loader: run CreateEvent() notify function based on flags

2017-07-03T11:48:51+00:00

The UEFI specification states that the tpl, function and context
arguments are to be ignored if neither EVT_NOTIFY_WAIT or
EVT_NOTIFY_SIGNAL are specified.  This matches observed behaviour with
an AMI EDK2 based UEFI implementation.

Skip calling the notify function if neither flag is present.

efi: Use device device path type Messaging for network interface node

2016-11-14T22:24:02+00:00

When adding network interface node use Messaging device path with
subtype MAC Address and device's MAC address as a value instead
of Media Device path type with subtype File Path and path "Net"

smbios: Expose in efi_loader as table

2016-10-19T07:01:52+00:00

We can pass SMBIOS easily as EFI configuration table to an EFI payload. This
patch adds enablement for that case.

While at it, we also enable SMBIOS generation for ARM systems, since they support
EFI_LOADER.
