libfdt: move headers to and

2018-03-05T15:16:28+00:00

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include       -> #include 
  #include   -> #include

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: do not install NULL as device path

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.

efi_loader: Always use EFIAPI instead of asmlinkage

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

EFI calls are usually defined as asmlinkage. That means we pass all parameters
to functions via the stack x86_32.

On x86_64 however, we need to also stick to the MS ABI calling conventions,
which the EFIAPI define conveniently handles for us. Most EFI functions were
also marked with EFIAPI, except for the entry call.

So this patch adjusts all entry calls to use EFIAPI instead of the manual
asmlinkage attribute.

While at it, we also change the prototype of the entry point to return
efi_status_t instead of ulong, as this is the correct prototype definition.

efi_loader: fix ExitBootServices

2018-01-22T22:09:14+00:00

This patch lets the implementation of ExitBootServices conform to
the UEFI standard.

The timer events must be disabled before calling the notification
functions of the exit boot services events.

The boot services must be disabled in the system table.

The handles in the system table should be defined as efi_handle_t.

efi_loader: add check_tpl parameter to efi_signal_event

2018-01-22T22:09:14+00:00

In ExitBootServices we need to signal events irrespective of the current
TPL level. A new parameter check_tpl is added to efi_signal_event().

Function efi_console_timer_notify() gets some comments.
