Add a simple app to use for testing. This is intended to do whatever it
needs to for testing purposes. For now it just prints a message and
exits boot services.

There was a considerable amount of discussion about whether it is OK to
call exit-boot-services and then return to U-Boot. This is not normally
done in a real application, since exit-boot-services is used to
completely disconnect from U-Boot. For now, this part is skipped.

Add a way to factor out the CFLAGS changes for each app, since they are

We have quite a few apps now, so create a way to specify them as a list
rather than repeating the same rules again and again.

This is not actually a command so the name is confusing. Use
BOOTEFI_HELLO_COMPILE instead. Put it in the efi_loader directory
with the other such config options.

The link rule (for $(obj)/%_efi.so) in scripts/Makefile.lib handles
pulling in efi_crt0.o and efi_reloc.o so drop the 'extra' rules.

Move distro_efi_get_fdt_name() to a separate C module
and rename it to efi_get_distro_fdt_name().

efi_var_collect() was initially placed in efi_var_file.c, since back
then we only supported efi variables stored in a file. Since then we
support variables stored in an RPMB as well and use that function to
collect variables that should be present at runtime.

So let's move it around in efi_var_common.c which makes more sense

efi_default_filename.h requires HOST_ARCH to be defined. Up to now we
defined it via a CFLAGS. This does not scale. Add the symbol to
version_autogenerated.h instead.

At this point, EFI boot manager interfaces is fully independent from
bootefi command. So just rename the configuration parameter.

Some code moved from cmd/bootefi.c is actually necessary only for "bootefi
<addr>" command (starting an image manually loaded by a user using U-Boot
load commands or other methods (like JTAG debugger).

The code will never been opted out as unused code by a compiler which
doesn't know how EFI boot manager is implemented. So introduce a new
configuration, CONFIG_EFI_BINARY_EXEC, to enforce them opted out
explicitly.

An EFI binary smbiosdump.efi is provided that can be used to check the
SMBIOS table for consistency and to dump it as a file.

The tool provides the following commands:

check
    Check the SMBIOS table for consistency.

exit
    Leave the tool.

help
    Show available commands.

save
    Save the SMBIOS table to a file on the EFI system partition. The file
    can be further analyzed with the dmidecode command line tool::

        dmidecode --from-dump <filename>

Specifying 'nocolor' as load option data suppresses colored output and
clearing of the screen.
