PowerPC has a 'btext' font used for the console which is almost identical
to the shared font_sun8x16, so use it rather than duplicating the data.
They were actually identical until about a decade ago when
commit bcfbeecea1 ("drivers: console: font_: Change a glyph from
"broken bar" to "vertical line"")
which changed the | in the shared font to be a solid
bar rather than a broken bar. That's the only difference.
This was originally spotted by the PMF source code analyser, which
noticed that sparc does the same thing with the same data, and they
also share a bunch of functions to manipulate the data. I've previously
posted a near identical patch for sparc.
Tested very lightly with a boot without FS in qemu.

Say Y here if you would like to use fonts other than the default
|
|
your frame buffer console usually use.
|

Note that the answer to this question won't directly affect the

kernel: saying N will just cause the configurator to skip all

|
the questions about foreign fonts.
|

If unsure, say N (the default choices are safe).

This is the "high resolution" font for the VGA frame buffer (the one

provided by the text console 80x50 (and higher) modes).

Note that this is a poor quality font. The VGA 8x16 font is quite a

lot more readable.

Given the resolution provided by the frame buffer device, answer N

here is safe.
