efi_loader: abort on unsupported relocation type

2017-07-04T07:03:00+00:00

If a relocation type is not supported loading the EFI binary
should be aborted.

Writing a message only is insufficient.

efi_loader: efi_handle_protocol set attributes

2017-07-04T07:01:23+00:00

UEFI spec 2.7 indicates that HandleProtocol can be implemented
by calling OpenProtocol with
attributes = EFI_OPEN_PROTOCOL_BY_HANDLE_PROTOCOL.

Currently we pass attributes = 0 to efi_open_protocol. 0 is not a
valid value when calling OpenProtocol. This does not cause any errors
yet because our implementation of OpenProtocol is incomplete.

We should pass the correct value to enable a fully compliant
implementation of OpenProtocol in the future.

efi_loader: check CreateEvent() parameters

Add some of the invalid parameter checks described in the UEFI
specification for CreateEvent().  This does not include checking
the validity of the type and tpl parameters.

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: Add a hook to allow adding memory mapping

Instead of adding all memory banks, add a hook so individual SoC/board
can has its own implementation.

efi_loader: Allow to compile helloworld.efi w/o bundling it

2016-11-27T14:53:39+00:00

Today we can compile a self-contained hello world efi test binary that
allows us to quickly verify whether the EFI loader framwork works.

We can use that binary outside of the self-contained test case though,
by providing it to a to-be-tested system via tftp.

This patch separates compilation of the helloworld.efi file from
including it in the u-boot binary for "bootefi hello". It also modifies
the efi_loader test case to enable travis to pick up the compiled file.
Because we're now no longer bloating the resulting u-boot binary, we
can enable compilation always, giving us good travis test coverage.

ls2080: Exit dpaa only right before exiting U-Boot

2016-11-17T13:18:55+00:00

On ls2080 we have a separate network fabric component which we need to
shut down before we enter Linux (or any other OS). Along with that also
comes configuration of the fabric using a description file.

Today we always stop and configure the fabric in the boot script and
(again) exit it on device tree generation. This works ok for the normal
booti case, but with bootefi the payload we're running may still want to
access the network.

So let's add a new fsl_mc command that defers configuration and stopping
the hardware to when we actually exit U-Boot, so that we can still use
the fabric from an EFI payload.

For existing boot scripts, nothing should change with this patch.
