cbd71fad6d test: Support tests which can only be run manually
At present we normally write tests either in Python or in C. But most
Python tests end up doing a lot of checks which would be better done in C.
Checks done in C are orders of magnitude faster and it is possible to get
full access to U-Boot's internal workings, rather than just relying on
the command line.

The model is to have a Python test set up some things and then use C code
(in a unit test) to check that they were done correctly. But we don't want
those checks to happen as part of normal test running, since each C unit
tests is dependent on the associate Python tests, so cannot run without
it.

To acheive this, add a new UT_TESTF_MANUAL flag to use with the C 'check'
tests, so that they can be skipped by default when the 'ut' command is
used. Require that tests have a name ending with '_norun', so that pytest
knows to skip them.

2783670583 watchdog: introduce a u-boot,autostart property
This is a companion to u-boot,noautostart. If one has a single
watchdog device that one does want to have auto-started, but several
others that one doesn't, the only way currently is to set the
CONFIG_WATCHDOG_AUTOSTART and then use the opt-out for the majority.

The main motivation for this is to add an autostarted watchdog device
to the sandbox (to test a fix) without having to set AUTOSTART in
sandbox_defconfig and add the noautostart property to the existing
devices. But it's also nice for symmetry, and the logic in
init_watchdog_dev() becomes simpler to read because we avoid all the
negations.

disable bootflow_system(), since EFI is not supported on
sandbox_flattree.

baf4141079 fdt: Show a message when the working FDT changes
The working FDT is the one which comes from the OS and is fixed up by
U-Boot. When the bootm command runs, it sets up the working FDT to be the
one it is about to pass to the OS, so that fixups can happen.

This seems like an important step, so add a message indicating that the
working FDT has changed. This is shown during the running of the bootm
command.

0b58eaa89c dm: core: Allow copying ofnode property data when writing
At present ofnode_write_prop() is inconsistent between livetree and
flattree, in that livetree requires the caller to ensure the property
value is stable (e.g. in rodata or allocated) but flattree does not, since
it makes a copy.

This makes the API call a bit painful to use, since the caller must do
different things depending on OF_LIVE.

Add a new 'copy' argument which tells the function to make a copy if
needed. Add some tests to cover this behaviour.

92291652b5 dm: core: Add the ofnode multi-tree implementation
Add the logic to redirect requests for the device tree through a function
which can look up the tree ID. This works by using the top bits of
ofnode.of_offset to encode a tree.

It is assumed that there will only be a few device trees used at runtime,
typically the control FDT (always tree ID 0) and possibly a separate FDT
to be passed the OS.

The maximum number of device trees supported at runtime is 8, with this
implementation. That would use bits 30:28 of the node-offset value,
meaning that the positive offset range is limited to bits 27:0, versus
30:1 with this feature disabled. That still allows a device tree of up
to 256MB, which should be enough for most FITs. Larger ones can be
supported by using external data with the FIT, or by enabling OF_LIVE.

Update the documentation a little and fix up the comment for
ofnode_valid().

0e4b697f88 test: Make a copy of the device tree before running a test
When the flat device tree changes it can mess up the live tree since that
uses the flat tree for its strings. This affects only a few sandbox tests
which modify the device tree, but the number will grow as ofnode support
for writing improves.

While the control FDT is not intended to change while U-Boot is running,
some tests do so. For example, the ofnode interface only supports
modifying properties in the control FDT, so tests must use that.

To solve this problem, keep a copy of the FDT and restore it as needed
when the test is finished. The copy only happens on sandbox (except SPL
builds), to reduce memory usage and because these tests are not useful on
other boards. For other boards, a checksum is taken to ensure that nothing
changes.

It would be possible to always checksum the FDT on sandbox and only
restore it if needed, but this is slightly slower than restoring it every
time, at least with crc8.

Move the code which checks for success to the very end, for clarity.

- SPL_BLK is not enabled, in which case (if we need block devices) we must

d1962ac797 Makefile: Add a pcheck option to run tests in parallel
Running tests in parallel is much faster, e.g. 15 seconds to run the tests
on sandbox (only), instead of 100 seconds (on a 16-core machine). Add a
'make pcheck' option to access this feature.

Note that the tools/ tests still run each tool's tests once after the
other, although within that, they do run in parallel. So for example,
the buildman tests run in parallel, then the binman tests run in
parallel. There would be a signiificant advantage to running them all
in parallel together, but that would require a large amount of
refactoring, e.g. with more use of pytest fixtures.

LTO (Link-Time Optimisation) is an very useful feature which can
significantly reduce the size of U-Boot binaries. So far it has been

However, incremental builds are much slower when LTO is used. For example,
an incremental build of sandbox takes 2.1 seconds on my machine, but 6.7
seconds with LTO enabled.

Add a NO_LTO parameter to the build, similar to NO_SDL, so it can be
disabled during development if needed, for faster builds.

dc0d17c26a cmd: Add pause command
This command is being introduced with the goal of allowing user-friendly
"generic use case" U-Boot builds to pause until user input under some
situations.

The main use case would be when a boot failure happens, to pause until
the user has had time to acknowledge the current state.

Tested using:

    make && ./u-boot -v -T -c 'ut lib lib_test_hush_pause'

Add bindings needed for accessing the FWU metadata regions.
These include the compatible string which point to the access
method, the actual device which stores the FWU metadata and
the offsets for both metadata regions.

The current patch adds basic bindings needed for accessing the
metadata structure on non-GPT mtd regions.

At present ofnode only works with a single device tree, for the most part.
This is the control FDT used by U-Boot.

When booting an OS we may obtain a different device tree and want to
modify it. Add some initial support for this into the ofnode API.

Note that we don't permit aliases in this other device tree, since the
of_access implementation maintains a list of aliases collected at
start-up. Also, we don't need aliases to do fixups in the other FDT. So
make sure that flat tree and live tree processing are consistent in this

When CONFIG_LOG is activated, if LOG_DEBUG is defined in a file and
DEBUG is not defined the trace with debug() macro are not displayed,
because the parameter cond : _DEBUG = 0 is checked in debug_cond().

With this patch the define DEBUG, used to force the trace generated by
debug() macro, is linked with the define LOG_DEBUG, used to force the
trace generated by other macros (log_debug, dev_dbg, pr_debug).

We only need to define LOG_DEBUG in a file to activate all the
traces generated by any U-Boot debug macro, as it is described in

1fc45d6483 watchdog: add pulse support to gpio watchdog driver
A common external watchdog circuit is kept alive by triggering a short
pulse on the reset pin. This patch adds support for this use case, while
making the algorithm configurable in the devicetree.

The "linux,wdt-gpio" driver being modified is based off the equivalent
driver in the Linux kernel, which provides support for this algorithm.
This patch brings parity to this driver, and is kept aligned with
the functionality and devicetree configuration in the kernel.

It should be noted that this adds a required property named 'hw_algo'
to the devicetree binding, following suit with the kernel. I'm happy to
make this backward-compatible if preferred.

Second, and more overarching, reword much of the section.  This expands

rebasing patches.  Rework the final points to be clearer that Custodians
are expected to do their best to test the changes and ask for help when

a568554ee0 doc: mkimage: Use standard style for synopsis
The synopsis section is a bit messy. As an example, "uimage file name" is
printed in italics, bold, and roman (depending on the line). This cleans
things up and converts the synopsis section to use standard style. The
.SY/.YS macros set up appropriate formatting for command synopsis sections
(such as disabling hyphenation and setting a hanging indent). All parts of
the synopsis now use the following style:

- Bold for parts of the command which should be typed in by the user (such
  as the program name and flags)
- Italic for parts which should be replaced (such as uimage-file-name)
- Roman for parts which should not be typed at all (such as brackets)

Multi-word variables now use hyphens to connect their words instead of
spaces. This makes it clearer that all the words are part of the same
variable. Additionally, "option ..." is used to denote where other options
may be specified, as this appears to be standard style.

In addition to the above style changes, this also makes some changes to
content. The use of the term "legacy" has been removed, since this simply
refers to any non-FIT image type. Additionally, wording like "uimage file
name" has been replaced with "image-file-name" to better reflect that
images may or may not be uImages. Lastly, the "auto" value for -f is
documented in the synopsis.

99e2fbcb69 linker_lists: Rename sections to remove . prefix
Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.

Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.

bfef72e4dd cmd: load: add load command for memory mapped
cp.b is used a lot as a way to load binaries to memory and execute
them, however we may need to integrate this with the efi subsystem to
set it up as a bootdev.

So, introduce a loadm command that will be consistent with the other
loadX commands and will call the efi API's.

ex: loadm $kernel_addr $kernel_addr_r $kernel_size

with this a kernel with CONFIG_EFI_STUB enabled will be loaded and
then subsequently booted with bootefi command.

c8ce7ba87d misc: Add support for nvmem cells
This adds support for "nvmem cells" as seen in Linux. The nvmem device
class in Linux is used for various assorted ROMs and EEPROMs. In this
sense, it is similar to UCLASS_MISC, but also includes
UCLASS_I2C_EEPROM, UCLASS_RTC, and UCLASS_MTD. New drivers corresponding
to a Linux-style nvmem device should be implemented as one of the
previously-mentioned uclasses. The nvmem API acts as a compatibility
layer to adapt the (slightly different) APIs of these uclasses. It also
handles the lookup of nvmem cells.

While nvmem devices can be accessed directly, they are most often used
by reading/writing contiguous values called "cells". Cells typically
hold information like calibration, versions, or configuration (such as
mac addresses).

nvmem devices can specify "cells" in their device tree:

	qfprom: eeprom@700000 {
		#address-cells = <1>;
		#size-cells = <1>;
		reg = <0x00700000 0x100000>;

		/* ... */

		tsens_calibration: calib@404 {
			reg = <0x404 0x10>;
		};
	};

which can then be referenced like:

	tsens {
		/* ... */
		nvmem-cells = <&tsens_calibration>;
		nvmem-cell-names = "calibration";
	};

The tsens driver could then read the calibration value like:

	struct nvmem_cell cal_cell;
	u8 cal[16];
	nvmem_cell_get_by_name(dev, "calibration", &cal_cell);
	nvmem_cell_read(&cal_cell, cal, sizeof(cal));

Because nvmem devices are not all of the same uclass, supported uclasses
must register a nvmem_interface struct. This allows CONFIG_NVMEM to be
enabled without depending on specific uclasses. At the moment,
nvmem_interface is very bare-bones, and assumes that no initialization
is necessary. However, this could be amended in the future.

Although I2C_EEPROM and MISC are quite similar (and could likely be
unified), they present different read/write function signatures. To
abstract over this, NVMEM uses the same read/write signature as Linux.
In particular, short read/writes are not allowed, which is allowed by
MISC.

The functionality implemented by nvmem cells is very similar to that
provided by i2c_eeprom_partition. "fixed-partition"s for eeproms does
not seem to have made its way into Linux or into any device tree other
than sandbox. It is possible that with the introduction of this API it
would be possible to remove it.

87b0af9317 mkimage: Support signing 'auto' FITs
This adds support for signing images in auto-generated FITs. To do this,
we need to add a signature node. The algorithm name property already has
its own option, but we need one for the key name hint. We could have
gone the -G route and added an explicit name for the public key (like
what is done for the private key). However, many places assume the
public key can be constructed from the key dir and hint, and I don't
want to do the refactoring necessary.

As a consequence of this, it is now easier to add public keys to an
existing image without signing something. This could be done all along,
but now you don't have to create an its just to do it. Ideally, we
wouldn't create a FIT at the end. This could be done by calling
fit_image_setup_sig/info.crypto->add_verify_data directly.
