Since switch to simplefb/simpledrm VESA graphic mode selection with vga= kernel parameter is no longer available with legacy BIOS. The x86 realmode boot code enables the VESA graphic modes when option FB_BOOT_VESA_SUPPORT is enabled. This option is selected by vesafb but not simplefb/simpledrm. To enable use of VESA modes with simplefb in legacy BIOS boot mode drop dependency of BOOT_VESA_SUPPORT on FB, also drop the FB_ prefix. Select the option from sysfb rather than the drivers that depend on it. The BOOT_VESA_SUPPORT is not specific to framebuffer but rather to x86 platform, move it from fbdev to x86 Kconfig.

The simpledrm driver uses the firmware provided video modes only indirectly through simplefb, and both can be enabled independently. v3: Move BOOT_VESA_SUPPORT from fbdev to x86 v4: Select BOOT_VESA_SUPPORT from sysfb rather than individial sysfb based drivers. --- arch/x86/Kconfig | 6 ++++++ arch/x86/boot/video-vesa.c | 4 ++-- drivers/firmware/Kconfig | 1 + drivers/video/fbdev/Kconfig | 12 ++---------- 4 files changed, 11 insertions(+), 12 deletions(-)
