From 8b766b0f8eece55155146f7628610ce54a065e0f Mon Sep 17 00:00:00 2001 From: Michal Suchanek Date: Fri, 25 Feb 2022 21:51:34 +0100 Subject: sysfb: Enable boot time VESA graphic mode selection 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.
