efi_loader: correct efi_disk_register

2018-02-09T23:25:49+00:00

efi_disk_register should return as status code (efi_status_t).

Disks with zero blocks should be reported as 'not ready' without throwing
an error.

This patch solves a problem running OpenBSD on system configured with
CONFIG_BLK=n (e.g. i.MX6).

efi_loader: do not use 2.0.5 as UEFI revision number

2018-02-09T23:24:00+00:00

Currently the UEFI revision number in the system table header is set to
2.0.5. This version number does not refer to any existing version of the
UEFI standard.

Set the revision number to 2.7.

efi_loader: create stub for CreateEventEx

2018-02-09T23:24:00+00:00

Currently we set the function pointer for the CreateEventEx boot service
to NULL. When called this would lead to an immediate failure.

A function stub is provided which handles the case that the boot service
is called without an event group and returns EFI_UNSUPPORTED otherwise.

efi_loader: fix building crt0 on arm

2018-02-09T23:24:00+00:00

Before the patch an undefined constant EFI_SUBSYSTEM was used in the
crt0 code. The current version of binutils does not swallow the error.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888403

The necessary constant IMAGE_SUBSYSTEM_EFI_APPLICATION is already
defined in pe.h. So let's factor out asm-generic/pe.h for the
image subsystem constants and use it in our assembler code.

IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification
let's use IMAGE_SUBSYSTEM_EFI_ROM instead.

The include pe.h is only used in code maintained by Alex so let him be the
maintainer here too.

Move most CONFIG_HAVE_BLOCK_DEVICE to Kconfig

2018-02-09T00:09:03+00:00

config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE
based on a list of enabled options.  Moving HAVE_BLOCK_DEVICE to
Kconfig allows us to drastically shrink the logic in
config_fallbacks.h

Convert LIB_UUID to Kconfig

2018-02-09T00:08:39+00:00

config_fallback.h has some logic that checks a variety of options
and selects LIB_UUID if it hasn't already been selected.  This
will all LIB_UUID in Kconfig and select this option for the list
of options to allow us to remove the logic from fallbacks

efi_loader: consistently use %pD to print device paths

2018-01-28T20:37:13+00:00

Now that we have %pD support in vsprintf we should avoid separate
logic for printing device paths in other places.

efi_loader: do not install NULL as device path

2018-01-28T20:37:13+00:00

In an image is loaded from memory we do not have a device path.
Do not install NULL as device path in this case.

efi_loader: Call Exit() on return from payload in StartImage()

2018-01-28T20:37:13+00:00

When a UEFI payload just returns instead of calling the Exit() callback,
we handle that in efi_do_enter() and call Exit on its behalf, so that
the loaded_image->exit_status value is correct.

We were missing that logic in StartImage(). Call it there too.
