3a2b6ba5cf test/py: Disable error E0611 in two cases for pylint
Recently pylint has started to complain about:
No name 'fs_helper' in module 'tests' (no-name-in-module)

Due to:
from tests import fs_helper

However, we have:
test/py/tests/fs_helper.py

And since we do not want to add a dummy test/py/tests/__init__.py to
silence this warning we instead just disable it as needed.

e2a9edc0ce Merge patch series "fs: fat: calculate FAT type based on cluster count"
To quote the author:

This series fixes an issue where the FAT type (FAT12, FAT16) is not
correctly detected, e.g. when the BPB field BS_FilSysType contains the
valid value "FAT     ".

This issue occures, for example, if a partition is formatted by
swupdate using its diskformat handler. swupdate uses the FAT library
from http://elm-chan.org/fsw/ff/ internally.

See https://groups.google.com/g/swupdate/c/7Yc3NupjXx8 for a
discussion in the swupdate mailing list.

Please refer to the commit messages for more details.

1. Added bootsector checks

Most tests from https://www.win.tue.nl/~aeb/linux/fs/fat/fat-2.html
are added in the commit 'fs: fat: add bootsector validity check'.
Only the tests VIII, IX and X are not implemented.

I also checked the Linux kernel code (v6.6) and did not find any
checks on 'vistart->fs_type'. This is the reason why is skipped them
here.

See section '2. Size comparisons' for the impact on the binary size.

2. Size comparisons

I executed bloat-o-meter from the Linux kernel for an arm64
target (config xilinx_zynqmp_mini_emmc0_defconfig):

Comparison of the binary spl/u-boot-spl between master (rev
e17d174773) and this patch
series (including the added validity checks of the boot sector):

add/remove: 0/0 grow/shrink: 1/1 up/down: 100/-12 (88)
Function                                     old     new   delta
read_bootsectandvi                           308     408    +100
fat_itr_root                                 444     432     -12
Total: Before=67977, After=68065, chg +0.13%

When compare the size of the binary spl/u-boot-spl between master this
series without the the validity checks of the boot sector:

add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-24 (-24)
Function                                     old     new   delta
read_bootsectandvi                           308     296     -12
fat_itr_root                                 444     432     -12
Total: Before=67977, After=67953, chg -0.04%

So the size of the spl on this arm64 target increases by 88 bytes for
this series. When i remove the validity check the size decreases by 24 bytes.

550862bc12 efi_loader: Boot var automatic management
Changes for complying to EFI spec §3.5.1.1
'Removable Media Boot Behavior'.
Boot variables can be automatically generated during a removable
media is probed. At the same time, unused boot variables will be
detected and removed.

Please note that currently the function 'efi_disk_remove' has no
ability to distinguish below two scenarios
a) Unplugging of a removable media under U-Boot
b) U-Boot exiting and booting an OS
Thus currently the boot variables management is not added into
'efi_disk_remove' to avoid boot options being added/erased
repeatedly under scenario b) during power cycles
See TODO comments under function 'efi_disk_remove' for more details

The original efi_secboot tests expect that BootOrder EFI variable
is not defined. With this commit, the BootOrder EFI variable is
automatically added when the disk is detected. The original
efi_secboot tests end up with unexpected failure.
The efi_secboot tests need to be modified to explicitly set
the BootOrder EFI variable.

squashfs and erofs ls tests are also affected by this modification,
need to clear the previous state before squashfs ls test starts.

11f834614e spl: Convert nand to spl_load
This converts the nand load method to use spl_load. nand_page_size may not
be valid until after nand_spl_load_image is called (see e.g. fsl_ifc_spl),
so we set bl_len in spl_nand_read. Since spl_load reads the header for us,
we can remove that argument from spl_nand_load_element.

There are two possible regressions which could result from this commit.
First, we ask for a negative address from spl_get_load_buffer. That is,
instead of

	header = spl_get_load_buffer(0, sizeof(*header));

we do

	header = spl_get_load_buffer(-sizeof(*header), sizeof(*header));

this could cause a problem if spl_get_load_buffer does not return valid
memory for negative offsets. Second, we now set bl_len for legacy images.
This can cause memory up to a bl_len - 1 before the image load address to
be written, which might not have been the case before. If this turns out to
be a problem, we can add an option for a bounce buffer.

We can't load FITs with external data with SPL_LOAD_FIT_FULL, so disable the
test in that case. No boards enable SPL_NAND_SUPPORT and SPL_LOAD_FIT_FULL, so
this is not a regression.

5d3401a448 spl: Convert mmc to spl_load
This converts the mmc loader to spl_load. Legacy images are handled by
spl_load (via spl_parse_image_header), so mmc_load_legacy can be
omitted. To accurately determine whether mmc_load_image_raw_sector is used
(which might not be the case if SYS_MMCSD_FS_BOOT is enabled), we introduce
a helper config SYS_MMCSD_RAW_MODE. This ensures we can inline spl_load
correctly when a board only boots from filesystems. We still need to check
for SPL_MMC, since some boards enable configure raw mode even without MMC
support.

afdd2d98c2 spl: Remove filename from spl_load_info
For filesystems, filename serves the same purpose as priv. However,
spl_load_fit_image also uses it to determine whether to use a DMA-aligned
buffer. This is beneficial for FAT, which uses a bounce-buffer if the
destination is not DMA-aligned. However, this is unnecessary now that
filesystems set bl_len to ARCH_DMA_MINALIGN instead. With this done, we can

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].

bc8e8a4bfa nand: Add sandbox driver
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.

3fa53b9531 bootstd: Add a return code to bootflow menu
Return an error when the user does not select an OS, so we know whether
to boot or not.

Move calling of bootflow_menu_run() into a separate function so we can
call it from other places.

Expand the test to cover these cases.

Add some documentation also, while we are here.

56ea7c8b75 CI, pytest: Add a test for sandbox without LTO
The primary motivation for having a sandbox without LTO build in CI is
to ensure that we don't have that option break. We now have the ability
to run tests of specific options being enabled/disabled, so drop the
parts of CI that build and test that configuration specifically and add
a build test instead. We still test that "NO_LTO=1" rather than editing
the config file works via the ftrace tests.

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.

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.

4fd7d27ccb test/py: always use autostart on tpm2 selftests
commit 789ed27842 ("test/py: replace 'tpm2 init, startup, selftest' sequences")
changed some of the tpm2 init sequences to 'tpm2 autostart' instead of
calling 'tpm init', 'tpm startup TPM2_SU_CLEAR', 'tpm2 self_test full'.

The autostart command calls the afforementioned sequence and on top of
that deals with the 'tpm2 init' return codes if the tpm is already
started. Since we initialize the tpm from various subsystems now,
replace the last remaining instances of 'tpm2 init' with 'tpm2
autostart'.  Since the latter calls 'tpm2 init' anyway we will still be
implicitly testing the validity of that command

It's worth noting that since 'tpm2 autostart' performs the startup and
self tests sequences of the tpm we could drop
'test_tpm2_sandbox_self_test_full' and 'test_tpm2_startup, but let's
keep the since they test tpm commands and options

539e2f7c10 test: use a non system PCR for testing PCR extend
We currently use PCR 0 for testing the PCR read/extend functionality in
our selftests.  How ever those PCRs are defined by the TCG spec for
platform use.  For example if the tests run *after* the efi subsystem
initialization, which extends PCRs 0 & 7 it will give a false positive.

So let's switch over to a PCR which is more suitable and is defined for
OS use.  It's worth noting that we are using PCR10 here, since PCR9 is
used internally by U-Boot if we choose to measure the loaded DTB
