efi_loader: LocateHandle should return EFI_NOT_FOUND if none found

2017-08-11T09:08:33+00:00

Spotted this debugging OpenBSD's bootloader in qemu.  (Wouldn't really
fix anything, the problem was not having any disks, but we should
probably return the correct error code.)

efi_loader: attribute EFIAPI of efi_locate handle()

2017-08-11T08:57:10+00:00

efi_locate_handle is called internally so it should not be
marked as EFIAPI.

The external function is efi_locate_handle_ext.

efi_loader: indent entry/exit prints to show nesting level

2017-07-28T22:18:46+00:00

This should make it easier to see when a callback back to UEFI world
calls back in to the u-boot world, and generally match up EFI_ENTRY()
and EFI_EXIT() calls.

efi_loader: add checking for incorrect use of EFI_ENTRY/EXIT

2017-07-28T22:18:24+00:00

Missing an EFI_ENTRY() or doubling up EFI_EXIT() leads to non-obvious
crashes.  Let's add some error checking.

efi_loader: Add an EFI_CALL() macro

2017-07-28T07:15:45+00:00

Rather than open-coding EFI_EXIT() + callback + EFI_ENTRY(), introduce
an EFI_CALL() macro.  This makes callbacks into UEFI world (of which
there will be more in the future) more concise and easier to locate in
the code.

efi_loader: Improve install_configuration_table

2017-07-26T13:23:54+00:00

The INSTALL_CONFIGURATION_TABLE callback also provides the ability to
remove table entries. This patch adds that functionality.

efi_loader: remove double EFI_EXIT() with efi_unsupported

2017-07-26T06:56:03+00:00

Probably this went unnoticed before, but it causes problems with
addition of 804b1d73 ("efi_loader: log EFI return values too")

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: workaround for grub lsefi bug

2017-07-24T12:47:36+00:00

Patch has also been sent to fix grub to not ignore the error returned
and treat protocol_buffer_count as valid.  But that that might take a
while to trickle into distro's, so this workaround might be useful.
