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

2017-07-03T11:54:48+00:00

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.

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.

efi_loader: Rename EFI_RUNTIME_{TEXT, DATA} to __efi_runtime{, _data}

2016-10-19T07:01:54+00:00

Compiler attributes are more commonly __foo style tags rather than big
upper case eye sores like EFI_RUNTIME_TEXT.

Simon Glass felt quite strongly about this, so this patch converts our
existing defines over to more eye friendly ones.

x86: efi: Add EFI loader support for x86

2016-10-19T07:01:53+00:00

Add the required pieces to support the EFI loader on x86.

Since U-Boot only builds for 32-bit on x86, only a 32-bit EFI application
is supported. If a 64-bit kernel must be booted, U-Boot supports this
directly using FIT (see doc/uImage.FIT/kernel.its). U-Boot can act as a
payload for both 32-bit and 64-bit EFI.

efi_loader: Fix efi_install_configuration_table

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

So far we were only installing the FDT table and didn't have space
to store any other. Hence nobody realized that our efi table allocation
was broken in that it didn't set the indicator for the number of tables
plus one.

This patch fixes it, allowing code to allocate new efi tables.

We want to be able to add configuration table entries from our own code as
well as from EFI payload code. Export the boot service function internally
too, so that we can reuse it.
