6910dbe341 env: Allow text-env tests to run with awk
At present the tests assume that gawk is being used. Adjust the tests so
that the names are inserted in alphabetical order, so that awk is happy.

Also use PROCINFO to make gawk output in alphabetical order. This is not
ideal, since it changes the env-car ordering from what the user provided,
but it may be acceptable.

fd426b3106 k210: use the board vendor name rather than the marketing name
"kendryte" is the marketing name for the K210 RISC-V SoC produced by
Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210"
vendor,SoC compatibility string format in the device tree files and
use the SoC name for file names.
With these changes, the device tree files are more in sync with the
Linux kernel DTS and drivers, making uboot device tree usable by the
kernel.

9de3773a5c event: Add a script to decode the event-spy list
For debugging and dicoverability it is useful to be able to see a list of
each event spy in a U-Boot ELF file. Add a script which shows this, along
with the event type and the source location. This makes events a little
easier to use than weak functions, for example.

Add a basic sandbox test as well. We could provide a test for other
boards, but for now, few use events.

10d3e5d20b firmware: scmi: fix sandbox and related tests for clock discovery
Updates sandbox SCMI clock driver and tests since enabling CCF will
mandate clock discovery that is all exposed SCMI clocks shall be
discovered at initialization. For this reason, sandbox SCMI clock
driver must emulate all clocks exposed by SCMI server, not only those
effectively consumed by some other U-Boot devices.

Therefore the sandbox SCMI test driver exposes 3 clocks (IDs 0, 1 and 2)
and sandbox SCMI clock consumer driver gets 2 of them.

This change updates sandbox test DT and sandbox SCMI driver accordingly

9876ae7db6 dm: Fix OF_BAD_ADDR definition
When OF_LIVE flag is enabled on a 64 bits platform, there is an
issue when dev_read_addr() is called and need to perform an address
translation using __of_translate_address().

In case of error, __of_translate_address() return's value is OF_BAD_ADDR
(wich is defined in include/dm/of.h to ((u64)-1) = 0xffffffffffffffff).
The return value of dev_read_addr() is often compared to FDT_ADDR_T_NONE
which is defined as (-1U) = 0xffffffff.
In this case the comparison is always false.

To fix this issue, define FDT_ADDR_T_NONE to (ulong)(-1) in case of
AARCH64. Update accordingly related tests.

31c27eb830 x86: Use the ACPI table writer
Use the new ACPI writer to write the ACPI tables. At present this is all
done in one monolithic function. Future work will split this out.

Unfortunately the QFW write_acpi_tables() function conflicts with the
'writer' version, so disable that for sandbox.

cc1f8c3988 x86: acpi: Split out context creation from base tables
At present acpi_setup_base_tables() both sets up the ACPI context and
writes out the base tables.

We want to use an ACPI writer to write the base tables, so split this
function into two, with acpi_setup_ctx() doing the context set, and
acpi_setup_base_tables() just doing the base tables.

Disable the writer's write_acpi_tables() function for now, to avoid
build errors. It is enabled in a following patch.

226fce6108 phy: Track power-on and init counts in uclass
On boards using the RK3399 SoC, the USB OHCI and EHCI controllers share
the same PHY device instance. While these controllers are being stopped
they both attempt to power-off and deinitialize it, but trying to
power-off the deinitialized PHY device results in a hang. This usually
happens just before booting an OS, and can be explicitly triggered by
running "usb start; usb stop" in the U-Boot shell.

Implement a uclass-wide counting mechanism for PHY initialization and
power state change requests, so that we don't power-off/deinitialize a
PHY instance until all of its users want it done. The Allwinner A10 USB
PHY driver does this counting in-driver, remove those parts in favour of
this in-uclass implementation.

The sandbox PHY operations test needs some changes since the uclass will
no longer call into the drivers for actions matching its tracked state
(e.g. powering-off a powered-off PHY). Update that test, and add a new
one which simulates multiple users of a single PHY.

The major complication here is that PHY handles aren't deduplicated per
instance, so the obvious idea of putting the counts in the PHY handles
don't immediately work. It seems possible to bind a child udevice per
PHY instance to the PHY provider and deduplicate the handles in each
child's uclass-private areas, like in the CLK framework. An alternative
approach could be to use those bound child udevices themselves as the
PHY handles. Instead, to avoid the architectural changes those would
require, this patch solves things by dynamically allocating a list of
structs (one per instance) in the provider's uclass-private area.
