freebsd/sys/sparc64/creator/creator_upa.c
Marius Strobl a2ffe82f1d - Declare lookup tables etc. const. 
- Let creator_bitblt() return ENODEV as it's not implemented (missed
  in sys/dev/fb/creator.c rev. 1.6).
- As a speed optimization inline the creator_ras_wait() etc. helper
  functions and also cache setting the font increment, font width
  and plane mask. [1]
- I got the meaning of V_DISPLAY_BLANK wrong, it's blank like turn
  off and not blank like turn on and clear the screen. So move
  clearing the screen to creator_clear() were it hopefully belongs.
- Properly implement V_DISPLAY_BLANK, V_DISPLAY_STAND_BY and
  V_DISPLAY_SUSPEND. This makes blank_saver.ko and green_saver.ko
  work. [1]
- Change the order of operations in creator_fill_rect(), i.e. write
  y before x and cy before cx. This fixes drawing the top part of
  the border with Elite3D cards when switching from Xorg to a VTY.
- Move setting the chip configuration we use and invalidating the
  cache variables to creator_set_mode() and set the V_ADP_MODECHANGE
  flag. This causes creator_set_mode() to be called when the X server
  shuts down which fixes the screen corruption caused most of the
  time by Xorg not restoring the original configuration present at
  startup.

Inspired by/based on:	Xorg [1]
