[PATCH] sparc32 vga support
sparc32 lacks vga.h, so lots of fbdev drivers won't compile. There are no sparc32 systems with PCI slots, so it's a bit moot. The patch gives sparc32 a copy of the sparc64 vga.h. It fixes sparc32 allmodconfig without mucking up fbdev Kconfig and gives us wider compile coverage. Cc: "Antonino A. Daplas" <adaplas@pol.net> Acked-by: "David S.
