Update the vidconsole API so that measure() can measure multiple lines
of text. This will make it easier to implement multi-line fields in
expo.
Tidy up the function comments while we are here.

Some drivers call video_set_flush_dcache() to indicate that they want to
have the dcache flushed for the frame buffer. These drivers benefit from
our new video damage control, because we can reduce the amount of memory
that gets flushed significantly.
This patch enables video damage control for all device drivers that call
video_set_flush_dcache() to make sure they benefit from it.

The dcache flushing code path was conditional on ARM && !DCACHE config
options. However, dcaches exist on other platforms as well and may need
clearing if their driver requires it.
Simplify the compile logic and always enable the dcache flush logic in
the video core. That way, drivers can always rely on it to call the arch
specific callbacks.
This will increase code size for non-ARM platforms with CONFIG_VIDEO=y
slightly.

CONFIG_VIDEO_COPY implemented a range-based copying mechanism: If we
print a single character, it will always copy the full range of bytes
from the top left corner of the character to the lower right onto the
uncached frame buffer. This includes pretty much the full line contents
of the printed character.
Since we now have proper damage tracking, let's make use of that to reduce
the amount of data we need to copy. With this patch applied, we will only
copy the tiny rectangle surrounding characters when we print them,
speeding up the video console.
After this, changes to the main frame buffer are not immediately copied
to the copy frame buffer, but postponed until the next video device
sync. So issue an explicit sync before inspecting the copy frame buffer
contents for the video tests.

Now that we have a damage area tells us which parts of the frame buffer
actually need updating, let's only dcache flush those on video_sync()
calls. With this optimization in place, frame buffer updates - especially
on large screen such as 4k displays - speed up significantly.

We are going to introduce image damage tracking to fasten up screen
refresh on large displays. This patch adds damage tracking for up to
one rectangle of the screen which is typically enough to hold blt or
text print updates. Callers into this API and a reduced dcache flush
code path will follow in later patches.

This series switches to always using $(PHASE_) in Makefiles when
building rather than $(PHASE_) or $(XPL_). It also starts on documenting
this part of the build, but as a follow-up we need to rename
doc/develop/spl.rst and expand on explaining things a bit.

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

Add support for the LCD interfaces (LCDIF1/2). When probed, these
interfaces request numerous clocks and power domains, attach the bridge
and look for a panel in order to retrieve its capabilities and
properties.
There is a similar existing driver in the upper folder for other i.MX
targets, I discovered this driver a bit late. It is not targeting the
i.MX8MP and I have no idea how different can the LCDIF be on this SoC,
but I did not manage to get it work, especially because it is not fully
compliant with the device-model, especially on the clocks/power
management side which is all ad-hoc. This is normal though, it was
contributed more than ten years ago.

Add support for the LVDS Display Bridge (LDB) found on i.MX8MP.
When attached, the bridge driver looks for panels connected to one of
its two outputs and adapts its own configuration to use them. There is
currently no support for merged/split displays.
Note regarding the clock configuration:
The LDB output clock should be absolutely identical to the LCDIF output
clock so both blocks can talk to each other synchronously. However, the
LDB clock has an internal divisor of 7 (respectively 3.5 in dual
configuration) which means the LDB input clock must be explicitly set
once we know the configuration.
This driver was tested on i.MX8MP using a single panel connected to the
LVDS2 interface.

Andre Przywara <[email protected]> says:
C's implicit fallthrough behaviour in switch/case statements can lead to
subtle bugs. Quite some while ago many compilers introduced warnings in
those cases, requiring intentional fallthrough's to be annotated.
So far we were not enabling that compiler option, so many ambiguities
and some bugs in the code went unnoticed.
This series adds the required annotations in code paths that the first
stage of the U-Boot CI covers. There is a large number of cases left
in the libbz2 code. The usage of switch/case is borderline insane there,
labels are hidden in macros, and there are no breaks, but just goto's.
Upstream still uses very similar code, without any annotations. I still
am not 100% sure those are meant to fall through or not, and plan to do
further investigations, but didn't want to hold the rest of the patches
back. You can see for yourself by applying patch 18/18 and building for
sandbox64, for instance.
Because of this we cannot quite enable the warning in the Makefile yet,
but those fixes are worth regardless, and be it to increase readability.
Please note that those patches do not fix anything, really, they just add
those fallthrough annotations, so the series is not really critical.

The generic DM video code uses an implicit switch/case fallthrough to
provide fallback code paths when certain colour depths are not enabled.
Add our "fallthrough;" statement-like macro to the video_fill() function
to avoid a warning when GCC's -Wimplicit-fallthrough warning option is
enabled.

Due to the use of the Tegra DC backlight feature by the HTC ONE X,
backlight requests MUST NOT be made during probe or earlier. This is
because it creates a loop, as the backlight is a DC child.
To mitigate this issue, backlight requests can be made later, once the
backlight is actively used.
