[PATCH] firmware: sysfb: Mark CONFIG_SYSFB_SIMPLEFB as deprecated

[Thomas Zimmermann <tzimmermann@suse.de>]

Mark CONFIG_SYSFB_SIMPLEFB as deprecated. Enabling it allows to
run simpledrm and simplefb on EFI/VESA framebuffers. Doing this
is discouraged in favor of using efidrm and vesadrm.

 	  Firmwares often provide initial graphics framebuffers so the BIOS,
 	  bootloader or kernel can show basic video-output during boot for
-	  user-guidance and debugging. Historically, x86 used the VESA BIOS

-	  to x86 BIOS or EFI systems.
-	  This option, if enabled, marks VGA/VBE/EFI framebuffers as generic
-	  framebuffers so the new generic system-framebuffer drivers can be
-	  used instead. If the framebuffer is not compatible with the generic
-	  modes, it is advertised as fallback platform framebuffer so legacy
-	  drivers like efifb, vesafb and uvesafb can pick it up.
-	  If this option is not selected, all system framebuffers are always
-	  marked as fallback platform framebuffers as usual.

-	  Note: Legacy fbdev drivers, including vesafb, efifb, uvesafb, will
-	  not be able to pick up generic system framebuffers if this option
-	  is selected. You are highly encouraged to enable simplefb as
-	  replacement if you select this option. simplefb can correctly deal
-	  with generic system framebuffers. But you should still keep vesafb
-	  and others enabled as fallback if a system framebuffer is
-	  incompatible with simplefb.
