OP-TEE has a format with a binary header that can be used instead of the
ELF file. With newer versions of OP-TEE this may be required on some
platforms.

Add support for this in binman. First, add a method to obtain the ELF
sections from an entry, then use that in the FIT support. We then end up
with the ability to support both types of OP-TEE files, depending on which
one is passed in with the entry argument (TEE=xxx in the U-Boot build).

At present only the image (which is a section) has a filename. Move this
implementation to the entry_Section class so that any section can have a
filename. With this, the section data is written to a file.

This allows parts of an image to be written, along with the entire image.

Make a note that this can be used to include the contents of a section in
one image in another (later) image.

This breaks chromebook_coral and it is also not how things should work. If
a board needs to bind GPIOs as part of a pinctrl driver this can be done
during the bind step, if needed.

We cannot probe pinctrl devices when binding as a rule, since it cannot be
supported on some platforms.

The bind and probe steps are separate in U-Boot and they should remain
separate.

The fdt_path_offset() function is slow since it must scan the tree.
This substantial overhead now applies to all boards.

The original code may not be ideal but it is fit for purpose and is only
needed on a few boards.

Reverting this reduces time to set up driver model by about 30ms.

This board is useful for benchmarking overall U-Boot performance. Enable
the bootstage feature so we get a report.

Since this returns to the boot rom before finishing executing
board_init_r() in SPL, add a few bootstage calls so that we can collect
timing from TPL.

For the stash region, use a portion of SRAM, 64KB below the stack top.
This allows the TPL image to be up to nearly 120KB (it is typically about
64KB). SPL normally runs from SDRAM at 0, so can use the same stash
region.

To quote the author:
So far standard boot lacks a boot menu, although it is possible to create
a rudimentary one using the existing 'bootmenu' command.

Even then, this text-based menu offer only basic functionality and does
not take full advantage of the displays which are common on many devices.

This series provides a 'bootflow menu' command which allows the user to
select from the available bootflows. An attempt is made to show the name
of the available operating systems, by reading more information into the
bootflow. A logo can be read also, where supported, so that this can be
presented to the user when an option is highlighted.

Full use is made of TrueType fonts, if enabled. For cases where only a
serial console is available, it falls back to a simple text-based menu.

All of this is implementing using a new 'expo' construct, a collection of
scenes (like menu screens) which can be navigated by the user to view
information and select options. This is fairly general and should be able
to cope with a wider array of use cases, with less hacking of the menu
code, such as is currently needed for CMD_BOOTEFI_BOOTMGR.

Of course it would be possible to enhance the existing menu rather than
creating a new setup. Instead it seems better to make the existing menu
use expo, if code space permits. It avoids the event-loop problem and
should be more extensible, given its loosely coupled components and use of
IDs instead of pointers. Further motivation is provided in the
documentation.

For now the CLI keypress-decoding code is split out to be used by the new
menu. The key codes defined by menu.h are reused also.

This is of course just a starting point. Some ideas for future work are
included in the documentation.

For Kirkwood boards, it is necessary to have early malloc in DRAM area
when Driver Model for Serial is enabled. Please see Michael's patch here:
https://lore.kernel.org/u-boot/20220817193809.1059688-20-michael@walle.cc/



This patch enables the early malloc in DRAM for all Kirkwood boards.
Note that this will work for boards that have either non-DM serial
and DM_SERIAL. Also, add the CONFIG_KIRKWOOD_COMMON option to enable
DM_SERIAL as a common option for boards that have been tested.

It was noticed that Clearfog is currently broken with this newly
introduced early_init_done() function. Apparently the timer is enabled
here when U-Boot is run but not configured - at least not correctly.
Resulting in a hangup in the timer reading functions.

To fix this, also read the value of the reload register and check it's
value with the one written to by U-Boot. Only if this matches, the
init has already been done.
