To quote the author:
This series tests raw nand flash in sandbox and fixes various bugs discovered in
the process. I've tried to do things in a contemporary manner, avoiding the
(numerous) variations present on only a few boards. The test is pretty minimal.
Future work could test the rest of the nand API as well as the MTD API.
Bloat (for v1) at [1] (for boards with SPL_NAND_SUPPORT enabled). Almost
everything grows by a few bytes due to nand_page_size. A few boards grow more,
mostly those using nand_spl_loaders.c. CI at [2].

Add a SPL test for the NAND load method. We use some different functions to
do the writing from the main test since things like nand_write_skip_bad
aren't available in SPL.
We disable BBT scanning, since scan_bbt is only populated when not in SPL.
We use nand_spl_loaders.c as it seems to be common to at least a few boards
already. However, we do not use nand_spl_simple.c because it would require
us to implement cmd_ctrl. The various nand load functions are adapted from
omap_gpmc. However, they have been modified for simplicity/correctness.

Add a sandbox NAND flash driver to facilitate testing. This driver supports
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.

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.

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.
Use the sandbox TPM driver to measure some boot images in a unit
test case.

Add a test for loading U-Boot over TFTP. As with other sandbox net
routines, we need to initialize our packets manually since things like

BOOTP instead of DHCP, since DHCP has a tag/length-based format which is
harder to parse. Our TFTP implementation doesn't define as many constants
as I'd like, so I create some here. Note that the TFTP block size is
one-based, but offsets are zero-based.
In order to avoid address errors, we need to set up/define some additional
address information settings. dram_init_banksize would be a good candidate
for settig up bi_dram, but it gets called too late in board_init_r.
