Takashi Iwai dfd19a5004 fonts: Prefer a bigger font for high resolution screens
Although we may have multiple fonts in kernel, the small 8x16 font is
chosen as default usually unless user specify the boot option.  This
is suboptimal for monitors with high resolutions.

This patch tries to assign a bigger font for such a high resolution by
calculating some penalty value.  This won't change anything for a
standard monitor like Full HD (1920x1080), but for a high res monitor
like UHD 4K, a bigger font like TER16x32 will be chosen once when
enabled in Kconfig.

Takashi Iwai 73a649d2b9 fonts: Use BUILD_BUG_ON() for checking empty font table
We have a nice macro, and the check of emptiness of the font table can
be done in a simpler way.

Amanoel Dawod ac8b6f148f Fonts: New Terminus large console font
This patch adds an option to compile-in a high resolution
and large Terminus (ter16x32) bitmap console font for use with
HiDPI and Retina screens.

The font was convereted from standard Terminus ter-i32b.psf
(size 16x32) with the help of psftools and minor hand editing
deleting useless characters.

This patch is non-intrusive, no options are enabled by default so most
users won't notice a thing.

I am placing my changes under the GPL 2.0 just as source Terminus font.

Maarten ter Huurne 33ac9dba85 fonts: Add 6x10 font
This font is suitable for framebuffer consoles on devices with a
320x240 screen, to get a reasonable number of characters (53x24) that
are still at a readable size.

The font is derived from the existing 6x11 font, but gets 3 extra
lines without sacrificing readability. Also I redesigned a some glyhps
so they are more distinct and better fill the available space.

Geert Uytterhoeven ee89bd6bc7 lib: Move fonts from drivers/video/console/ to lib/fonts/
Several drivers need font support independent of CONFIG_VT, cfr. commit
9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font
support code selection logic").
Hence move the fonts and their support logic from drivers/video/console/ to
its own library directory lib/fonts/.
This also allows to limit processing of drivers/video/console/Makefile to
CONFIG_VT=y again.
