powerpc: Fix flush_cache() speed regression

Flushing kernel image after decompression was taking 113 milliseconds
with U-boot 2022.10. With U-boot 2023.01 and 2023.04, flushing
the same amount of memory takes approx 1.5 seconds. With
U-boot 2023.07-rc6, it takes 6.5 seconds.

powerpc flush_cache() function used to call WATCHDOG_RESET() after
flushing every cacheline. At that time WATCHDOG_RESET() was light
so the operation was almost seamless.

But commit 29caf9305b6 ("cyclic: Use schedule() instead of
WATCHDOG_RESET()") replaced WATCHDOG_RESET() by schedule() and that
started to hurt with U-boot 2022.10.

And in U-boot 2023.07-rc6 that's even worse after
commit 26e8ebcd7cb ("watchdog: mpc8xxx: Make it generic").

In the meantime commit 729c1fe656 ("powerpc: introduce
CONFIG_CACHE_FLUSH_WATCHDOG_THRESHOLD") gives us the opportinity to
only call schedule() every given chunk of data instead of every
cacheline. As explained in that commit there is no point in pinging
the watchdog after every cacheline flush, so lets define a sensible
default chunk size of 4k which matches to size of a page on most
powerpc platforms.

With that new default threshold, the culprit flushing performed after
kernel image decompression now takes 85 milliseconds on a powerpc 8xx.

lzma: Fix decompression speed regression

Uncompressing a 1.7Mbytes FIT image on U-boot 2023.04 takes
approx 7s on a powerpc 8xx.
The same on U-boot 2023.07-rc6 takes approx 28s unless watchdog
is disabled.

During that decompression, LzmaDec_DecodeReal() calls schedule
1.6 million times, that is every 4µs in average.

In the past it used to be a call to WATCHDOG_RESET() which was
just calling hw_watchdog_reset().

But the combination of commit 29caf9305b6 ("cyclic: Use schedule()
instead of WATCHDOG_RESET()") and commit 26e8ebcd7cb ("watchdog:
mpc8xxx: Make it generic") results in an heavier processing.

However, there is absolutely no point in calling schedule() that
often.

By moving and keeping only one call to schedule() in the main
loop the number of calls is reduced to 1.2 million which is still
too much. So add logic to only call schedule every 1024 times.
That leads to a call to schedule approx every 6ms which is still
far enough to entertain the watchdog which has a 1s timeout on
powerpc 8xx.

powerpc 8xx being one of the slowest targets we have today in
U-boot, and most other watchdogs having a timeout of one minutes
instead of one second like the 8xx, this fix should not have
negative impact on other targets.

TASK_TAG as 0 inside u-boot ufs framework. So, instead we

board_f: Relocate fdt even if GD_FLG_SKIP_RELOC is set

In case of OF_SEPARATE (!OF_EMBED), the devicetree blob is placed
after _end, and fdt_find_separate() always returns _end. There is
a .bss section after _end and the section is cleared before relocation.

When GD_FLG_SKIP_RELOC is set, relocation is skipped, so the blob is
still in .bss section, but will be cleared. As a result, the devicetree
become invalid.

To avoid this issue, should relocate it regardless of GD_FLG_SKIP_RELOC

- A number of updates for the nuvoton family of platforms

Merge branch '2023-07-14-expo-initial-config-editor'

To quote the author:
This series provides a means to edit board configuration in U-Boot in a
graphical manner. It supports multiple menu items and allows moving
between them and selecting items. The configuration is defined in a data
format so that code is not needed in most cases. This allows the board
configuration to be provided in the devicetree.

This is still at an early stage, since it only supports menus. Numeric
values are not supported. Most importantly it does not yet support
loading or saving the configuration selected by the user.

To try it out you can use something like:

    ./tools/expo.py -e test/boot/files/expo_layout.dts \
        -l test/boot/files/expo_layout.dts -o cedit.dtb
    ./u-boot -Tl -c "cedit load hostfs - cedit.dtb; cedit run"

Use the arrow keys to move between menus, enter to open a menu, escape
to exit.

Various minor fixes and improvements are provided in this series:
- Update STB TrueType library to latest
- Support clearing part of the video display
- Support multiple livetrees loaded at runtime
- Support loading and allocating a file
- Support proper measuring of text in expo
- Support simple themes for expo

cat: Update command to use fs_load_alloc()

Use this new function since it implements the required functionality and
reduces duplicated code.

fs: Create functions to load and allocate a file

This functionality current sits in bootstd, but it is more generally
useful. Add a function to load a file into memory, allocating it as
needed. Adjust bootstd to use this version.

Note: Tests are added in the subsequent patch which converts the 'cat'
command to use this function.

expo: Rename exp_set_text_mode()

Rename this function to match its peers, using the full "expo' prefix.

console: Correct truetype spacing error

The putc_xy() method is supposed to return the amount of space used. The
existing implementation erroneously adds the previous sub-pixel position
to the returned value. This spaces out the characters very slightly more
than it should. It is seldom noticeable but it does make accurate
measurement of the text impossible.

Fix this minor but long-standing bug.

expo: Avoid automatically arranging the scene

This should ideally be done once after all scene changes have been made.
Require an explicit call when everything is ready.

Always arrange after a key it sent, just for convenience.

expo: Store the console in the expo

Rather than finding this each time, keep a pointer to it. This simplifies
the code a little.

video: Provide a way to clear part of the console

This is useful when the background colour must be written before text
is updated, to avoid strange display artifacts.

Add a function for this, using the existing code from the truetype
console.

video: Drop #ifdefs from console_truetype

Use if() instead to reduce the number of build paths.

dm: core: Avoid registering an inaccessible tree

At present there are various restrictions on the use of livetree:

- It is only available once the tree is unflattened, i.e. after relocation
- It is designed to be used with the control FDT
- It can (in principle) be used with other FDTs, but only if they are
unflattened first; this is not supported

Add a few checks to make sure that any tree that is created is actually
valid. Otherwise it can be confusing when nodes and properties cannot
actually be accessed.

gpio: Avoid using an invalid ofnode

Devices do not necessarily have nodes attached to them, since they can be
created from platdata. In SPL a devicetree may in fact not exist at all.

Check the node before using it. This avoids failure when OF_CHECKS is
enabled.

test: Restore test behaviour on failure

A recent change makes test continue to run after failure. This results in
a lot of useless output and may lead to a segfault. Fix this by adding
back the 'return' statement.

sandbox: Fix quiting when the LCD window is closed

With recent changes to how sandbox handles reset, closing the window
currently just restarts sandbox.

expo: Convert to using a string ID for the scene title

This is easier to deal with if it uses the existing string handling,

bdinfo: Correct use of assertions

This test was written for the incorrect use of assertions. Update it to
build with the previous approach, where tests fail at the first
assertion.

All assertion functions return 0 on success and non-zero on failure.
They can be nested into functions simply by declaring a function that
returns an int and using ut_assertok() to call it.
