The fs_open has been extended with support for open flags.
Currently supported flags are:
FS_O_READ -- open for read
FS_O_WRITE -- open for write
FS_O_CREATE -- create file if it does not exist
FS_O_APPEND -- move to the end of file before each write
The FAT FS and LittleFS front-ends within the Zephyr has also been
modified to utilize the flags.

In fat_fs example, if we choose a large size SD card to connect with,
the result of memory size calculation coule be wrong due to the missing
brace for manipulating operator priority.

Refactors the fat_fs sample yaml to depend on a feature rather than
whitelisting specific boards. This implicitly extends the sample to
mimxrt10{60,64}_evk boards, since they already support the feature.
The only whitelist board remaining is the nrf52840_blip, which requires
a device tree overlay for this sample.

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

The $srctree environment variable is already set to point to the Zephyr
root, so no need to do
source "$(ZEPHYR_BASE)/Kconfig.zephyr"
in samples. Just
source "Kconfig.zephyr"
works.
(Things would break if $srctree was set to anything else, because every
'source' in the Kconfig files will be relative to it.)
Also add a 'mainmenu' title to the littlefs sample. It shows up at the
top of menuconfig/guiconfig. Source Kconfig.zephyr instead of Kconfig to
avoid overriding it.
As a sidenote, $(FOO) is better $FOO in Kconfig. $FOO is legacy syntax
that Kconfiglib only supports to be compatible with old Linux kernels.
$(FOO) uses the Kconfig preprocessor.

Use this short header style in all Kconfig files:

...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just

It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

There's desire to be able to customize parameters on a per-filesystem
basis, which means we need a way to override the Kconfig defaults which
are global. This also means the littlefs data structure cannot own the
cache and lookahead buffers.
Switch to using a macro to define the littlefs data structure. The
default version uses the Kconfig constants. A custom one takes
arguments providing the most likely partition-specific parameters.
Finally the user is free to bypass the helper macros and set any
parameters desired, though validation is limited and only present when
CONFIG_DEBUG is enabled.
Extend the test suite with a performance module, which confirms that
these settings have an impact proportional to the log of changes to the
cache or IO sizes.

YAML document separators are needed e.g. when doing
$ cat doc1.yaml doc2.yaml | <parser>
For the bindings, we never parse concatenated documents. Assume we don't
for any other .yaml files either.
Having document separators in e.g. base.yaml makes !include a bit
confusing, since the !included files are merged and not separate
documents (the merging is done in Python code though, so it makes no
difference for behavior).
The replacement was done with
$ git ls-files '*.yaml' | \
xargs sed -i -e '${/\s*\.\.\.\s*/d;}' -e 's/^\s*---\s*$//'
First pattern removes ... at the end of files, second pattern clears a
line with a lone --- on it.
Some redundant blank lines at the end of files were cleared with
$ git ls-files '*.yaml' | xargs sed -i '${/^\s*$/d}'
This is more about making sure people can understand why every part of a
binding is there than about removing some text.
