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: only evaluate EFI_EXIT()'s ret once

2017-07-28T07:14:01+00:00

There are a couple spots doing things like:

   return EFI_EXIT(some_fxn(...));

which I handn't noticed before.  With addition of printing return value
in the EFI_EXIT() macro, now the fxn call was getting evaluated twice.
Which we didn't really want.

efi_loader: add helper macro to construct protocol objects

2017-07-25T08:55:51+00:00

There are a bunch of protocols which should be exposed by GUID but are
not.  Add a helper macro to create an efi_object, to avoid much typing.

Note that using the pointer for efiobj->handle is semi-arbitrary.  We
just need a unique value to match the efiobj supporting the protocol
with the handle that LocateHandle() returns..

See LibLocateProtocol() in gnu-efi.  It does LocateHandle() to find all
the handles, and then loops over them calling HandleProtocol() with the
GUID of the protocol it is trying to find.

efi_loader: log EFI return values too

2017-07-25T08:29:46+00:00

Turns out this is rather useful to tracking down where things fail.

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.

Set up a timer event and the WaitForKey event.
In the notify function of the timer event check for console input
and signal the WaitForKey event accordingly.

efi_loader: refactor efi_set_timer

2017-07-19T12:31:40+00:00

efi_set_timer is refactored to make the function callable internally.
Wrapper function efi_set_timer_ext is provided for EFI applications.
