Add kconfig menus for most chipset VIDEO_MB values.
VIDEO_MB is a variable that defines how many MB of RAM will be used for onboard graphics frame buffer. It's northbridge-dependent which values for CONFIG_MB are valid (but not board-dependent). This patch adds choices for menuconfig to select the VIDEO_MB value for: - Intel 82810 - Intel 82830 - VIA CN400 - VIA CN700 Note: CN400 and CN700 are based on the CX700 datasheet, not sure if they're correct. If somebody has CN400 and CN700 datasheets, please verify. We drop all per-board VIDEO_MB variables in per-board Kconfig files as there's a northbridge-specific option/default now (plus the user can override the value if needed in menuconfig). As CONFIG_MB is chipset-specific but not board-specific (and never was), filter it in util/compareboard/compareboard, we don't need to match those values. Finally, put "CPU", "Northbridge", "Southbridge", "Super I/O", and "Devices" sections into the "Chipset" menu, where NB-specific options will appear if you select a board using a certain NB, SB-specific options would appear in the "Southbridge" section etc. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Myles Watson <mylesgw@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4866 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
