[PATCH] console/font: Refactor font support code selection logic

From: Geert Uytterhoeven
Date: Wed May 15 2013 - 07:41:31 EST


The current Makefile rules to build font support are messy and buggy.
Replace them by Kconfig rules:
- Introduce CONFIG_FONT_SUPPORT, which controls the building of all font
code,
- Select CONFIG_FONT_SUPPORT for all drivers that use fonts,
- Select CONFIG_FONT_8x16 for all drivers that default to the VGA8x16
font,
- Drop the bogus console dependency for CONFIG_VIDEO_VIVI.

This fixes (if CONFIG_SOLO6X10=y and there are no built-in console
drivers):

drivers/built-in.o: In function `solo_osd_print':
drivers/staging/media/solo6x10/solo6x10-enc.c:144: undefined reference to `.find_font'
