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.

GPMC stands for General Purpose Memory Controller and it is
present on many Texas Instruments SoCs.
It supports a number of Asynchronous and Synchronous interfaces
and has various settings to configure the bus interface.
The DT bindings define all the various GPMC settings.
As the GPMC supports multiple devices on the bus, each
device is represented as a child and the respective
GPMC settings are situated there. (see ti,gpmc-child.yaml)
These binding docs are picked up from the Linux kernel.

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

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.

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.

because the parameter cond : _DEBUG = 0 is checked in debug_cond().

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

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.

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.

actually be inline literals (and not italics). The content of this

Set kernel_comp_addr_r and kernel_comp_size for compressed kernel.
Adjust existing addresses for ramdisk, so that kernel_comp_addr_r
comes before the ramdisk image, since the decompressed kernel size
is known to us. This way we can allow big ramdisk image to be loaded.
Update unleashed.rst to remove the manual environment configuration
for compressed kernel boot.

Add an initial VPL build for sandbox. This includes the flow:
TPL (with of-platdata) -> VPL -> SPL -> U-Boot
To run it:
./tpl/u-boot-tpl -D
The -D is needed to get the default device tree, which includes the serial
console info.
Add a Makefile check for OF_HOSTFILE which is the option that enables
devicetree control on sandbox.

To quote the author:
The bootflow feature provide a built-in way for U-Boot to automatically
boot an Operating System without custom scripting and other customisation.
This is called 'standard boot' since it provides a standard way for
U-Boot to boot a distro, without scripting.
It introduces the following concepts:
- bootdev - a device which can hold a distro
- bootmeth - a method to scan a bootdev to find bootflows (owned by
U-Boot)
- bootflow - a description of how to boot (owned by the distro)
This series provides an implementation of these, enabled to scan for
bootflows from MMC, USB and Ethernet. It supports the existing distro
boot as well as the EFI loader flow (bootefi/bootmgr). It works
similiarly to the existing script-based approach, but is native to
U-Boot.
With this we can boot on a Raspberry Pi 3 with just one command:
bootflow scan -lb
which means to scan, listing (-l) each bootflow and trying to boot each
one (-b). The final patch shows this.
With a standard way to identify boot devices, booting become easier. It
also should be possible to support U-Boot scripts, for backwards
compatibility only.
...
The design is described in these two documents:

A 'bootdev' is a device which can be used to boot an operating system.
It is a child of the media device (e.g. MMC) which handles reading files
from that device, such as a bootflow file.
Add a uclass for bootdev and the various helpers needed to make it
work. Also add a binding file, empty for now.
