1431ab8b6c efi_loader: Don't carve out memory reservations too early
Moving the efi_carve_out_dt_rsv() call in commit 1be415b21b
("efi_loader: create memory reservations in ACPI case")
broke boards that create additional memory reservations in
ft_board_setup() since it is now called before those additional
memory reservations are made.  This is the case for the rk3588
boards and breaks booting OpenBSD on those boards.

Move the call back to its original location and add a call in
the code path used for ACPI.

50457f547d efi_loader: simplify error message in efi_disk_create_raw()
The error message

    Adding disk for usb_mass_storage.lun0 failed (err=-9223372036854775788/0x8000000000000014)

provides a decimal and a hexadecimal notation of the EFI status code
EFI_ALREADY_STARTED which is defined as (EFI_ERROR_MASK | 20).
The decimal output does not convey the value 20 clearly.

With the patch we write

    Adding block device usb_mass_storage.lun0 failed, r = 20

similar to other EFI error messages.

6ebf9136ec smbios: if a string value is unknown, use string number 0
The SMBIOS specification describes: "If a string field references no string,
a null (0) is placed in that string field."

Accordingly we should avoid writing a string "Unknown" to the SMBIOS table.

dmidecode displays 'Not Specified' if the string number is 0.

Commit 00a871d34e ("smbios: empty strings in smbios_add_string()")
correctly identified that strings may not have length 0 as two
consecutive NULs indentify the end of the string list. But the suggested
solution did not match the intent of the SMBIOS specification.

f19171c919 efi_loader: Clean up efi_dp_append and efi_dp_concat
Looking back at the initrd storing functionality, we introduced three
functions, efi_dp_append_or_concatenate(), efi_dp_append/concat(). In
hindsight we could have simplified that by a lot. First of all none of
the functions append anything. They all allocate a new device path and
concatenate the contents of two device paths in one. A boolean parameter
controls the final device path -- if that's true an end node is injected
between the two device paths.

So let's rewrite this and make it a bit easier to read. Get rid of
efi_dp_append(), efi_dp_concat() and rename
efi_dp_append_or_concatenate() to efi_dp_concat(). This is far more
intuitive and the only adjustment that is needed is an extra boolean
argument on all callsites.

8aec703111 efi_loader: provide tool to dump SMBIOS table
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.

efe441a0a3 smbios: smbios.h should not import ofnode.h
The smbios.h include does not use any definitions from ofnode.h.
So don't include it.

As DECLARE_GLOBAL_DATA_PTR is no longer defined via dm/of.h we need to
add it to efi_smbios.c.

Add now missing includes to smbios-parser.c.

Remove a superfluous check comparing the sizes of the SMBIOS 2.1 and SMBIOS
3.0 anchors.

does. Replace it. table_compute_checksum() is always compiled.

e3db8d60be lib: make table_compute_checksum() arguments const
table_compute_checksum() does neither changes the content of the
checksummed buffer nor the buffer length. Adding const to the

b2f088c121 acpi: Kconfig symbol CONFIG_QFW_ACPI
We have two implementations of write_acpi_tables(). One for writing ACPI
tables based on ACPI_WRITER() entries another based on copying tables from
QEMU.

Create a symbol CONFIG_QFW_ACPI that signifies copying ACPI tables from
QEMU and use it consistently.
