caa5edc39c test: Add mmc13 and mmc14 devices for TKey and pre-derived
Add two new MMC test devices:

- mmc13: LUKS2 encrypted with TKey-derived key, for testing TKey-based
  disk encryption unlock
- mmc14: LUKS2 encrypted with a known master key, for testing the
  pre-derived master key unlock path

The test setup generates keys matching the TKey emulator's deterministic
output. An override.bin file can be used to test with a physical TKey.

797a952213 tkey: Add a sandbox driver for real TKey hardware
Add a sandbox TKey driver that enables communication with physical TKey
devices via serial port (/dev/ttyACM0). This allows testing TKey
functionality in sandbox with real hardware.

The driver:
  - Opens the configured device path from device tree
  - Configures TTY parameters using os_tty_set_params()
  - Implements read/write operations for TKey protocol
  - Supports both read() and read_all() operations

Device tree configuration:

  tkey-test {
    compatible = "sandbox,tkey";
    sandbox,device-path = "/dev/ttyACM0";
  };

tkey: Provide basic support for Tillitis TKey
This device provides a way to sign data using an internal, unique key.
It can be useful for features such as unlocking an encrypted disk.

This series provides basic support for the Tkey, with a uclass, two
sandbox drivers (emulator and serial), a simple command some tests.

e27b36c015 expo: Tidy up insets and improve tests
Insets are handled inconsistently at present, since menus use them to
offset the label text, whereas textlines don't. This is done because
menus need the margin to be visible when opened. However this causes an
alignment issue when menus and textlines appear in the same cedit.

Remove the offsets from menus and compensate by adjusting the bounding
boxes used for highlighting and the opened menu.

Line up menu items and textlines vertically and add a style option for
textlines to control how much padding is added.

Add a test to check the positions of objects in a cedit, since this is
more direct than the rendering tests. Add style information so that the
impact can be seen.

2800aecce0 Merge patch series "Implement ACPI on aarch64"
Patrick Rudolph <patrick.rudolph@9elements.com> says:

Based on the existing work done by Simon Glass this series adds
support for booting aarch64 devices using ACPI only.
As first target QEMU SBSA support is added, which relies on ACPI
only to boot an OS. As secondary target the Raspberry Pi4 was used,
which is broadly available and allows easy testing of the proposed
solution.

The series is split into ACPI cleanups and code movements, adding
Arm specific ACPI tables and finally SoC and mainboard related
changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the
mandatory ACPI tables are supported, allowing to boot into Linux
without errors.

The QEMU SBSA support is feature complete and provides the same
functionality as the EDK2 implementation.

The changes were tested on real hardware as well on QEMU v9.0:

qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \
                    -pflash secure-world.rom \
                    -pflash unsecure-world.rom

qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \
-smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \
-dtb bcm2711-rpi-4-b.dtb -nographic

Tested against FWTS V24.03.00.

Known issues:
- The QEMU rpi4 support is currently limited as it doesn't emulate PCI,
  USB or ethernet devices!
- The SMP bringup doesn't work on RPi4, but works in QEMU (Possibly
  cache related).
- PCI on RPI4 isn't working on real hardware since the pcie_brcmstb
  Linux kernel module doesn't support ACPI yet.

f116feadea drivers: misc: irq-uclass: Update irq_get_by_index
Support reading the "interrupts" property from the devicetree in case
the "interrupts-extended" property isn't found. As the "interrupts"
property is commonly used, this allows to parse all existing FDT and
makes irq_get_by_index() more useful.

The "interrupts" property doesn't contain a phandle as "interrupts-extended"
does, so implement a new method to locate the interrupt-parent called
irq_get_interrupt_parent().

TEST: Read the interrupts from the GIC node for ACPI MADT generation.

360aaddd9c Merge patch series "Make LMB memory map global and persistent"
Sughosh Ganu <sughosh.ganu@linaro.org> says:

This is a follow-up from an earlier RFC series [1] for making the LMB
and EFI memory allocations work together. This is a non-rfc version
with only the LMB part of the patches, for making the LMB memory map
global and persistent.

This is part one of a set of patches which aim to have the LMB and EFI
memory allocations work together. This requires making the LMB memory
map global and persistent, instead of having local, caller specific
maps. This is being done keeping in mind the usage of LMB memory by
platforms where the same memory region can be used to load multiple
different images. What is not allowed is to overwrite memory that has
been allocated by the other module, currently the EFI memory
module. This is being achieved by introducing a new flag,
LMB_NOOVERWRITE, which represents memory which cannot be re-requested
once allocated.

The data structures (alloced lists) required for maintaining the LMB
map are initialised during board init. The LMB module is enabled by
default for the main U-Boot image, while it needs to be enabled for
SPL. This version also uses a stack implementation, as suggested by
Simon Glass to temporarily store the lmb structure instance which is
used during normal operation when running lmb tests. This does away
with the need to run the lmb tests separately.

The tests have been tweaked where needed because of these changes.

The second part of the patches, to be sent subsequently, would work on
having the EFI allocations work with the LMB API's.

[1] - https://lore.kernel.org/u-boot/20240704073544.670249-1-sughosh.ganu@linaro.org/T/#t

Notes:

1) These patches are on next, as the alist patches have been
   applied to that branch.
2) I have tested the boot on the ST DK2 board, but it would be good to
   get a T-b/R-b from the ST maintainers.
3) It will be good to test these changes on a PowerPC platform
   (ideally an 85xx, as I do not have one).

9b19e207a9 sandbox: move the TCG event log to the start of ram memory
The TCG event log buffer is being set at the end of ram memory. This
region of memory is to be reserved as LMB_NOMAP memory in the LMB
memory map. The current location of this buffer overlaps with the
memory region reserved for the U-Boot image, which is at the top of
the usable memory. This worked earlier as the LMB memory map was not
global but caller specific, but fails now because of the overlap.

Move the TCG event log buffer to the start of the ram memory region
instead. Move the location of the early trace buffer and the load
buffer for U-Boot(spl boot) accordingly.

any number of devices, each using a single chip-select. The OOB data is
stored in-band, with the separation enforced through the API.

For now, create two devices to test with. The first is a very small device
with basic ECC. The second is an 8G device (chosen to be larger than 32
bits). It uses ONFI, with the values copied from the datasheet. It also
doesn't need too strong ECC, which speeds things up.

Although the nand subsystem determines the parameters of a chip based on
the ID, the driver itself requires devicetree properties for each
parameter. We do not derive parameters from the ID because parsing the ID
is non-trivial. We do not just use the parameters that the nand subsystem
has calculated since that is something we should be testing. An exception
is made for the ECC layout, since that is difficult to encode in the device
tree and is not a property of the device itself.

Despite using file I/O to access the backing data, we do not support using
external files. In my experience, these are unnecessary for testing since
tests can generally be written to write their expected data beforehand.
Additionally, we would need to store the "programmed" information somewhere
(complicating the format and the programming process) or try to detect
whether block are erased at runtime (degrading probe speeds).

Information about whether each page has been programmed is stored in an
in-memory buffer. To simplify the implementation, we only support a single
program per erase. While this is accurate for many larger flashes, some
smaller flashes (512 byte) support multiple programs and/or subpage
programs. Support for this could be added later as I believe some
filesystems expect this.

To test ECC, we support error-injection. Surprisingly, only ECC bytes in
the OOB area are protected, even though all bytes are equally susceptible
to error. Because of this, we take care to only corrupt ECC bytes.
Similarly, because ECC covers "steps" and not the whole page, we must take
care to corrupt data in the same way.

bd9ff681bd serial: zynqmp: Fetch baudrate from dtb and update
The baudrate configured in .config is taken by default by serial. If
change of baudrate is required then the .config needs to changed and
u-boot recompilation is required or the u-boot environment needs to be
updated.

To avoid this, support is added to fetch the baudrate directly from the
device tree file and update.
The serial, prints the log with the configured baudrate in the dtb.
The commit c4df0f6f31 ("arm: mvebu: Espressobin: Set default value for
$fdtfile env variable") is taken as reference for changing the default
environment variable.

The default environment stores the default baudrate value, When default
baudrate and dtb baudrate are not same glitches are seen on the serial.
So, the environment also needs to be updated with the dtb baudrate to
avoid the glitches on the serial.

Also add test to cover this new function.

d5d9770f58 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.
