Module Name:    src

Modified Files:

        src/sys/arch/x68k/dev: ite.c ite_tv.c itevar.h

Log Message:
x68k: Add SIXEL graphics sequence support.
- The palette definition is fixed to the same color as the text (currently,
  it's RGB 8 colors).  Any palette definition sent will be ignored.
- Aspect ratio and bg color mode is not supported (yet).
- An OR mode is supported.  This is proposed by Y.Sugahara in this
  implementation and then the mlterm also supports it.  It's an advantageous
  way for the multi plane color VRAM.
- ITE_SIXEL kernel option is added and is disabled by default for now.

It was first written by me in 2014 and has been demonstrated in Open Source
Conference Hiroshima every year since then.  In this year, it's also
demonstrated on real X68030 at Japan NetBSD Users Group booth in OSC 2024
Hiroshima, last week.

It's useful for showing and explaining about the possibility of NetBSD and
old machines for younger (than X68030) engineers or students.
