cb32266d4a video: Allow console output to be silenced
When using expo we want to be able to control the information on the
display and avoid other messages (such as USB scanning) appearing.

Add a 'quiet' flag for the console, to help with this.

The test is a little messy since stdio is still using the original
vidconsole create on start-up. So take care to use the same.

70dfd67478 video: Use VIDEO_DAMAGE for VIDEO_COPY
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.

6398e1149f video: test: Support checking copy frame buffer contents
The video tests have a helper function to generate a pseudo-digest of
frame buffer contents, but it only does so for the main one. There is
another check that the copy frame buffer is the same as that. But
neither is enough to test if only the modified regions are copied to the
copy frame buffer, since we will want the two to be different in very
specific ways.

Add a boolean argument to the existing helper function to indicate which
frame buffer we want to inspect, and update the existing callers.

a8f80409b0 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

At present when the console is rotated 180 degrees it starts almost a
whole character to the left of the right edge (typically 7 pixels with
an 8-pixel-wide font). On a display which aligns with the font width,
this just wastes space. On a display that does not this can result in
x_frac going negative for the final character (the one on the left
side) and the overflow -EAGAIN check at the start of the function
failing.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
