Today of_address_to_resource() is called only in
ofnode_read_resource() for livetree support and
fdt_get_resource() is called when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required, but the address translation is done
by ofnode_read_resource() caller, for example in
drivers/firmware/scmi/smt.c::scmi_dt_get_smt_buffer() {
...
	ret = ofnode_read_resource(args.node, 0, &resource);
	if (ret)
		return ret;

	faddr = cpu_to_fdt32(resource.start);
	paddr = ofnode_translate_address(args.node, &faddr);
...

The both behavior should be aligned and the address translation
must be called in fdt_get_resource() and removed for each caller.

At present each invocation of run_steps() updates OUTPUT_FILES_COMMON,
since it does not make a copy of the dict. This is fine for a single
invocation, but for tests, run_steps() is invoked many times.

As a result it may include unwanted items from the previous run, if it
happens that a test runs twice on the same CPU. The problem has not been
noticied previously, as there are few enough tests and enough CPUs that
is is rare for the 'wrong' combination of tests to run together.

Fix this by making a copy of the dict, before updating it. Update the
tests to suit, taking account of the files that are no-longer generated.

With this fix, we no-longer generate files which are not needed for a

When CONFIG_USE_DEFAULT_ENV_FILE=y and the file
CONFIG_DEFAULT_ENV_FILE is empty (or at least doesn't contain any
non-comment, non-empty lines), we end up feeding nothing into xxd,
which in turn then outputs nothing. Then blindly appending ", 0x00"
means that we end up trying to compile (roughly)

const char defaultenv[] = { , 0x00 }

which is of course broken.

To fix that, change the frobbing of the text file so that we always
end up printing an extra empty line (which gets turned into that extra
nul byte we need) - that corresponds better to the binary format
consisting of a series of key=val nul terminated strings, terminated

- WDT: Enable use of hw_margin_ms=0
- PowerPC: Introduce CONFIG_CACHE_FLUSH_WATCHDOG_THRESHOLD
- PowerPC: Misc changes and fixes to the WDT handling

When flush_cache() is called during boot on our ~7M kernel image, the
hundreds of thousands of WATCHDOG_RESET calls end up adding
significantly to boottime. Flushing a single cache line doesn't take
many microseconds, so doing these calls for every cache line is
complete overkill.

The generic watchdog_reset() provided by wdt-uclass.c actually
contains some rate-limiting logic that should in theory mitigate this,
but alas, that rate-limiting must be disabled on powerpc because of
its get_timer() implementation - get_timer() works just fine until
interrupts are disabled, but it just so happens that the "big"
flush_cache() call happens in the part of bootm where interrupts are
indeed disabled. [1] [2] [3]

I have checked with objdump that the generated code doesn't change
when this option is left at its default value of 0: gcc is smart
enough to see that the ">=" comparison is tautologically true, hence
all assignments to "flushed" are eliminated as dead stores.

On our board, setting the option to something like 65536 ends up
reducing total boottime by about 0.8 seconds.

Having WATCHDOG_RESET() called automatically from the timer interrupt
runs counter to the idea of a watchdog device - if the board runs into
an infinite loops with interrupts still enabled, the watchdog will
never fire.

When using CONFIG_(SPL_)WDT, the watchdog_reset function is a lot more
complicated than just poking a few SOC-specific registers - it
involves accessing all kinds of global data, and if the interrupt
happens at the wrong time (say, in the middle of an WATCHDOG_RESET()
call from ordinary code), that can end up corrupting said global data.

Allow the board to opt out of calling WATCHDOG_RESET() from the timer
interrupt handler by setting CONFIG_SYS_WATCHDOG_FREQ to 0 - as that
setting is currently nonsensical (it would be compile-time
divide-by-zero), it cannot affect any existing boards.

Add documentation for both the existing and extended meaning of
CONFIG_SYS_WATCHDOG_FREQ.

Some boards don't work with the rate-limiting done in the generic
watchdog_reset() provided by wdt-uclass.

For example, on powerpc, get_timer() ceases working during bootm since
interrupts are disabled before the kernel image gets decompressed, and
when the decompression takes longer than the watchdog device
allows (or enough of the budget that the kernel doesn't get far enough
to assume responsibility for petting the watchdog), the result is a
non-booting board.

As a somewhat hacky workaround (because DT is supposed to describe
hardware), allow specifying hw_margin_ms=0 in device tree to
effectively disable the ratelimiting and actually ping the watchdog
every time watchdog_reset() is called. For that to work, the "has
enough time passed" check just needs to be tweaked a little to allow
the now==next_reset case as well.

Commit eb5a2b67 ("net: sun8i-emac: Determine pinmux based on SoC,

CONFIG_MACH_SUN* symbols, to find the appropriate mux value.
Unfortunately this patch missed to check for the H5, which is
pin-compatible to the H3, but uses a different Kconfig symbol (because
it has ARMv8 vs. ARMv7 cores).

Replace the pure SUN8I_H3 symbol with the joint SUNXI_H3_H5 one, which is
there to cover the peripherals common to both SoCs.
Also explicitly list each supported SoC, and have an error message in the
fallback case, to avoid those problems in the future.
