67e6966078 reset: fix reset_get_by_index_nodev index handling
This fixes an issue getting resets index 1 and 3+, the spurius "> 0"
made it return the index 0 or 1, whatever index was passed.

The dm_test_reset_base() did not catch it, but the dm_test_reset_base() extension
catches it and this fixes the regression.

This also fixes a reggression on Amlogic G12A/G12B SoCs, where HDMI output was disable
even when Linux was booting.

7ac7038ab3 Makefile: fix generation of defaultenv.h from empty initial file
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
by an empty string.

dae9aeda45 fs: btrfs: fix the false alert of decompression failure
There are some cases where decompressed sectors can have padding zeros.

In kernel code, we have lines to address such situation:

        /*
         * btrfs_getblock is doing a zero on the tail of the page too,
         * but this will cover anything missing from the decompressed
         * data.
         */
        if (bytes < destlen)
                memset(kaddr+bytes, 0, destlen-bytes);
        kunmap_local(kaddr);

But not in U-boot code, thus we have some reports of U-boot failed to
read compressed files in btrfs.

Fix it by doing the same thing of the kernel, for both inline and
regular compressed extents.

729c1fe656 powerpc: introduce CONFIG_CACHE_FLUSH_WATCHDOG_THRESHOLD
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.

933ada560b allow opting out of WATCHDOG_RESET() from timer interrupt
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.

2156016294 timer: mpc83xx_timer: fix build with CONFIG_{HW_, }WATCHDOG
The code, which is likely copied from arch/powerpc/lib/interrupts.c,
lacks a fallback definition of CONFIG_SYS_WATCHDOG_FREQ and refers to
a non-existing timestamp variable - obviously priv->timestamp is
meant.

7dd2097e21 watchdog: use time_after_eq() in watchdog_reset()
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.
