video: move fbdev to drivers/video/fbdev
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

- * Some technical notes:
- *
- * The BSC FrameMaster II (or Rainbow II) is a simple very dumb
- * frame buffer which allows to display 24 bit true color images.
- * Each pixel is 32 bit width so it's very easy to maintain the
- * frame buffer. One long word has the following layout:
- * AARRGGBB which means: AA the alpha channel byte, RR the red
- * channel, GG the green channel and BB the blue channel.
- *
- * The FrameMaster II supports the following video modes.
- * - PAL/NTSC
- * - interlaced/non interlaced
- * - composite sync/sync/sync over green
- *
- * The resolution is to the following both ones:
- * - 768x576 (PAL)
- * - 768x480 (NTSC)
- *
- * This means that pixel access per line is fixed due to the
- * fixed line width. In case of maximal resolution the frame
- * buffer needs an amount of memory of 1.769.472 bytes which
- * is near to 2 MByte (the allocated address space of Zorro2).
- * The memory is channel interleaved. That means every channel
- * owns four VRAMs. Unfortunately most FrameMasters II are
- * not assembled with memory for the alpha channel. In this
- * case it could be possible to add the frame buffer into the
- * normal memory pool.
- *
- * At relative address 0x1ffff8 of the frame buffers base address
- * there exists a control register with the number of
- * four control bits. They have the following meaning:
- * bit value meaning
- *
- * 0 1 0=interlaced/1=non interlaced
- * 1 2 0=video out disabled/1=video out enabled
- * 2 4 0=normal mode as jumpered via JP8/1=complement mode
- * 3 8 0=read onboard ROM/1 normal operation (required)
- *
- * As mentioned above there are several jumper. I think there
- * is not very much information about the FrameMaster II in
- * the world so I add these information for completeness.
- *
- * JP1 interlace selection (1-2 non interlaced/2-3 interlaced)
- * JP2 wait state creation (leave as is!)
- * JP3 wait state creation (leave as is!)
- * JP4 modulate composite sync on green output (1-2 composite
- * sync on green channel/2-3 normal composite sync)
- * JP5 create test signal, shorting this jumper will create
- * a white screen
- * JP6 sync creation (1-2 composite sync/2-3 H-sync output)
- * JP8 video mode (1-2 PAL/2-3 NTSC)
- *
- * With the following jumpering table you can connect the
- * FrameMaster II to a normal TV via SCART connector:
- * JP1: 2-3
- * JP4: 2-3
- * JP6: 2-3
- * JP8: 1-2 (means PAL for Europe)
- *
- * NOTE:
- * There is no other possibility to change the video timings
- * except the interlaced/non interlaced, sync control and the
- * video mode PAL (50 Hz)/NTSC (60 Hz). Inside this
- * FrameMaster II driver are assumed values to avoid anomalies
- * to a future X server. Except the pixel clock is really
- * constant at 30 MHz.
- *
- * 9 pin female video connector:
- *
- * 1 analog red 0.7 Vss
- * 2 analog green 0.7 Vss
- * 3 analog blue 0.7 Vss
- * 4 H-sync TTL
- * 5 V-sync TTL
- * 6 ground
- * 7 ground
- * 8 ground
- * 9 ground
- *
- * Some performance notes:
- * The FrameMaster II was not designed to display a console
- * this driver would do! It was designed to display still true
- * color images. Imagine: When scroll up a text line there
- * must copied ca. 1.7 MBytes to another place inside this
- * frame buffer. This means 1.7 MByte read and 1.7 MByte write
- * over the slow 16 bit wide Zorro2 bus! A scroll of one
- * line needs 1 second so do not expect to much from this
- * driver - he is at the limit!
