d502c5f3b4 powerpc: Drop version_string placement optimization
As explained by Wolfgang, historically PowerPC would do a number of
things to hand-optimize placement of the binary on NOR flash in order to
maximize utilization of very scarce resources.  These days, we simply
aren't optimizing our binary layout for NOR flash placement and it's
quite likely this wasn't working as intended.  Furthermore, this level
of optimization makes it difficult to have version_string be a global,
instead of a weak and overridden value, and so make more progress on
reproducible builds, which is a current concern.

Move to having PowerPC no longer store version_string in the early part
of text so that it might be part of the first page of NOR and instead
use the same declaration everyone else does.

Introduce select statements for other architectures based on current

to the generic symbol.  This lets us remove a little bit of otherwise
unused code.

efb5dab7ba nxp: Migrate CONFIG_DDR_CLK_FREQ to Kconfig
As this symbol can either be a fixed value or the function
get_board_ddr_clk, migration is tricky.  Introduce a choice of DYNAMIC
or STATIC_DDR_CLK_FREQ.  If DYNAMIC, we continue to use the board
defined get_board_ddr_clk function.  If STATIC, set CONFIG_DDR_CLK_FREQ
to that value and now include/clock_legacy.h contains the function
prototype or defines get_board_ddr_clk() to that static value.  Update
callers to test for DYNAMIC or STATIC.

13ea307f79 board: freescale: t208xrdb: add a config option for rev D dts fixups
Under DM, we rely on u-boot's device tree to provide the correct PHY
addresses. The board_fix_fdt callback is intended to be used for
device tree fixups before relocation. Unfortunately, this isn't an
option when booting from flash since the device tree isn't writable
before relocation.

This patch introduces the CONFIG_T2080RDB_REV_D option to signal that a
board revision D or up is the target. The config option is used to set
the correct Aquantia PHY address in the board's u-boot device tree.

Defconfig files with the option enable explicitly are added for
convenience.

This was causing a consistent hard lockup during the MMC read / loading

Re-adding the header causes identical assembly to be emitted and allows
the firmware loading and subsequent boot to succeed.

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.
