This adds TCPM framework in preparation for fusb302 support, which can
handle USB power delivery messages. This is needed to solve issues with
devices, that are running from a USB-C port supporting USB-PD, but not
having a battery.
Such a device currently boots to the kernel without interacting with
the power-supply at all. If there are no USB-PD message replies within
5 seconds, the power-supply assumes the peripheral is not capable of
USB-PD. It usually takes more than 5 seconds for the system to reach
the kernel and probe the I2C based fusb302 chip driver. Thus the
system always runs into this state. The power-supply's solution to
fix this error state is a hard reset, which involves removing the
power from VBUS. Boards without a battery (or huge capacitors) will
reset at this point resulting in a boot loop.
This imports the TCPM framework from the kernel. The porting has
originally been done by Rockchip using hardware timers and the Linux
kernel's TCPM code from some years ago.
I had a look at upgrading to the latest TCPM kernel code, but that
beast became a lot more complex due to adding more USB-C features.
I believe these features are not needed in U-Boot and with multiple
kthreads and hrtimers being involved it is non-trivial to port them.
Instead I worked on stripping down features from the Rockchip port
to an even more basic level. Also the TCPM code has been reworked
to avoid complete use of any timers (Rockchip used SoC specific
hardware timers + IRQ to implement delayed work mechanism). Instead
the delayed state changes are handled directly from the poll loop.
Note, that (in contrast to the original Rockchip port) the state
machine has the same hard reset quirk, that the kernel has - i.e.
it avoids disabling the CC pin resistors for devices that are not
self-powered. Without that quirk, the Radxa Rock 5B will not just
end up doing a machine reset when a hard reset is triggered, but will
not even recover, because the CPU will loose power and the FUSB302
will keep this state because of leak voltage arriving through the RX
serial pin (assuming a serial adapter is connected).
This also includes a 'tcpm' command, which can be used to get
information about the current state and the negotiated voltage
and current.

With the relatively new button API in U-Boot, it's now much easier to
model the common usecase of mapping arbitrary actions to different
buttons during boot - for example entering fastboot mode, setting some
additional kernel cmdline arguments, or booting with a custom recovery
ramdisk, to name a few.
Historically, this functionality has been implemented in board code,
making it fixed for a given U-Boot binary and requiring the code be
duplicated and modified for every board.
Implement a generic abstraction to run an arbitrary command during boot
when a specific button is pressed. The button -> command mapping is
configured via environment variables with the following format:
button_cmd_N_name=<button label>
button_cmd_N=<command to run>
Where N is the mapping number starting from 0. For example:
button_cmd_0_name=vol_down
button_cmd_0=fastboot usb 0
This will cause the device to enter fastboot mode if volume down is held
during boot.
After we enter the cli loop the button commands are no longer valid,
this allows the buttons to additionally be used for navigating a boot
menu.

Merge tag 'tpm-next-27102023' of https://source.denx.de/u-boot/custodians/u-boot-tpm
bootX measurements and measurement API moved to u-boot core:
Up to now, U-Boot could perform measurements and EventLog creation as
described by the TCG spec when booting via EFI.
The EFI code was residing in lib/efi_loader/efi_tcg2.c and contained
both EFI specific code + the API needed to access the TPM, extend PCRs
and create an EventLog. The non-EFI part proved modular enough and
moving it around to the TPM subsystem was straightforward.
With that in place we can have a common API for measuring binaries
regardless of the boot command, EFI or boot(m|i|z), and contructing an
EventLog.
I've tested all of the EFI cases -- booting with an empty EventLog and
booting with a previous stage loader providing one and found no
regressions. Eddie tested the bootX part.
Eddie also fixed the sandbox TPM which couldn't be used for the EFI code
and it now supports all the required capabilities. This had a slight
sideeffect in our testing since the EFI subsystem initializes the TPM
early and 'tpm2 init' failed during some python tests. That code only
opens the device though, so we can replace it with 'tpm2 autostart'
which doesn't error out and still allows you to perfom the rest of the
tests but doesn't report an error if the device is already opened.
There's a few minor issues with this PR as well but since testing and
verifying the changes takes a considerable amount of time, I prefer
merging it now.
Heinrich has already sent a PR for -master containing "efi_loader: fix
EFI_ENTRY point on get_active_pcr_banks" and I am not sure if that will
cause any conflicts, but in any case they should be trivial to resolve.
Both the EFI and non-EFI code have a Kconfig for measuring the loaded
Device Tree. The reason this is optional is that we can't reason
when/if devices add random info like kaslr-seed, mac addresses etc in
the DT. In that case measurements are random, board specific and
eventually useless. The reason it was difficult to fix it prior to this
patchset is because the EFI subsystem and thus measurements was brought
up late and DT fixups might have already been applied. With this
patchset we can measure the DT really early in the future.
Heinrich also pointed out that the two Kconfigs for the DTB measurements
can be squashed in a single one and that the documentation only explains
the non-EFI case. I agree on both but as I said this is a sane working
version, so let's pull this first it's aleady big enough and painful to
test.
I initially didn't find the bootz docs when I went looking for them. :)

Adds a command called "gpt transpose" which will swap the order two
partition table entries in the GPT partition table (but leaves them
pointing to the same locations on disk).
This can be useful for swapping bootloaders in systems that use an A/B
partitioning scheme where the bootrom is hard coded to look for the
bootloader in a specific index in the GPT partition table.

This is a stub describing how TPL, VPL, and SPL load the next boot stages
on a detail level for users.
For sure we will need a few patches on top to catch the whole complexity.

definition to indicate which registers and bits are used.

Add a command to write cedit settings to CMOS RAM so that it can be
preserved across a reboot. This uses a simple bit-encoding, where each
field has a 'bit position' and a 'bit length' in the schema.
