Some tests can have race conditions which are hard to detect on a single
one. Add a way to run tests more than once, to help with this.

Each individual test is run the requested number of times before moving
to the next test. If any runs failed, a message is shown.

This is most useful when running a single test, since running all tests
multiple times can take a while.

LTO (Link-Time Optimisation) is an very useful feature which can
significantly reduce the size of U-Boot binaries. So far it has been
made available for selected ARM boards and sandbox.

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.

Add some documentation about LTO while we are here.

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'

Since both pm8916.c and pm8916_gpio.c are already supporting multiple
Qcom SoCs, it makes sense to rename these drivers to pmic_qcom.c and
qcom_pmic_gpio.c respectively. Also, these driver can be extended to
support additional functionality if required for other Qcom SoCs.

Along with this import latest DT binding: qcom,spmi-pmic.txt from Linux
kernel and thereby remove pm8916.txt.

Simon Glass authored 2 years ago and Tom Rini committed 2 years ago

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
area.

The unflattening algorithm results in a single block of memory being
allocated for the whole tree. When writing new properties, these are
allocated new memory outside that block. When the block is freed, the
allocated properties remain.

Document how this works and the potential memory leak, as well as
mentioning that updating the livetree is actually supported now.

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

A common external watchdog circuit is kept alive by triggering a short

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.
