From 63a8f2a7c29bb41191be085ca328c3938e774902 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Mon, 26 Oct 2009 21:42:13 +0000 Subject: 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 Acked-by: Myles Watson git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4866 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/northbridge/via/cn400/Kconfig | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) (limited to 'src/northbridge/via/cn400/Kconfig') diff --git a/src/northbridge/via/cn400/Kconfig b/src/northbridge/via/cn400/Kconfig index c210d934a1..67703c9ebe 100644 --- a/src/northbridge/via/cn400/Kconfig +++ b/src/northbridge/via/cn400/Kconfig @@ -17,3 +17,36 @@ config PCI_ROM_RUN default n depends on NORTHBRIDGE_VIA_CN400 +# TODO: Values are from the CX700 datasheet, not sure if this matches CN400. +# TODO: What should be the per-chipset default value here? +choice + prompt "Onboard graphics" + default CN400_VIDEO_MB_32MB + depends on NORTHBRIDGE_VIA_CN400 + +# TODO: Disabling onboard graphics is not yet supported in the source code. +config CN400_VIDEO_MB_OFF + bool "Disabled, 0KB" +config CN400_VIDEO_MB_8MB + bool "Enabled, 8MB" +config CN400_VIDEO_MB_16MB + bool "Enabled, 16MB" +config CN400_VIDEO_MB_32MB + bool "Enabled, 32MB" +config CN400_VIDEO_MB_64MB + bool "Enabled, 64MB" +config CN400_VIDEO_MB_128MB + bool "Enabled, 128MB" + +endchoice + +config VIDEO_MB + int + default 0 if CN400_VIDEO_MB_OFF + default 8 if CN400_VIDEO_MB_8MB + default 16 if CN400_VIDEO_MB_16MB + default 32 if CN400_VIDEO_MB_32MB + default 64 if CN400_VIDEO_MB_64MB + default 128 if CN400_VIDEO_MB_128MB + depends on NORTHBRIDGE_VIA_CN400 + -- cgit v1.2.3
