-/************************************************************************
- Get Parameters for the video mode:
- The default video mode can be defined in CFG_DEFAULT_VIDEO_MODE.
- If undefined, default video mode is set to 0x301
- Parameters can be set via the variable "videomode" in the environment.
- 2 diferent ways are possible:
- "videomode=301" - 301 is a hexadecimal number describing the VESA
- mode. Following modes are implemented:
-
- Colors 640x480 800x600 1024x768 1152x864 1280x1024
- --------+---------------------------------------------
- 8 bits | 0x301 0x303 0x305 0x161 0x307
- 15 bits | 0x310 0x313 0x316 0x162 0x319
- 16 bits | 0x311 0x314 0x317 0x163 0x31A
- 24 bits | 0x312 0x315 0x318 ? 0x31B
- --------+---------------------------------------------
- "videomode=bootargs"
- - the parameters are parsed from the bootargs.
- The format is "NAME:VALUE,NAME:VALUE" etc.
- Ex.:
- "bootargs=video=ctfb:x:800,y:600,depth:16,pclk:25000"
- Parameters not included in the list will be taken from
- the default mode, which is one of the following:
- mode:0 640x480x24
- mode:1 800x600x16
- mode:2 1024x768x8
- mode:3 960x720x24
- mode:4 1152x864x16
- mode:5 1280x1024x8
-
- if "mode" is not provided within the parameter list,
- mode:0 is assumed.
- Following parameters are supported:
- x xres = visible resolution horizontal
- y yres = visible resolution vertical
- pclk pixelclocks in pico sec
- le left_marging time from sync to picture in pixelclocks
- ri right_marging time from picture to sync in pixelclocks
- up upper_margin time from sync to picture
- lo lower_margin
- hs hsync_len length of horizontal sync
- vs vsync_len length of vertical sync
- sync see FB_SYNC_*
- vmode see FB_VMODE_*
- depth Color depth in bits per pixel
- All other parameters in the variable bootargs are ignored.
- It is also possible to set the parameters direct in the
- variable "videomode", or in another variable i.e.
- "myvideo" and setting the variable "videomode=myvideo"..
