video/drm: display: add support for video console mode
In video console mode, the logs will be showed in the panel/monitor.
To enable the video console mode, the following Kconfig options are
required:
/* enable the video console */
CONFIG_ROCKCHIP_VIDCONSOLE=y
The default horizontal resolution of video console is the minimum
&drm_display_mode.crtc_hdisplay of the VPs, and the vertical
resolution is the minimum &drm_display_mode.crtc_vdisplay. The bits
per pixel is set to 32 by default.
To set the resolution of video console to 1920x1080 with 16bpp
manually, the following Kconfig options should be set:
/* the resolution of the video console */
CONFIG_ROCKCHIP_VIDCONSOLE_WIDTH=1920
CONFIG_ROCKCHIP_VIDCONSOLE_HEIGHT=1080
/* the bits per pixel the of video console */
CONFIG_ROCKCHIP_VIDCONSOLE_BPP32 is not set
CONFIG_ROCKCHIP_VIDCONSOLE_BPP16=y
CONFIG_ROCKCHIP_VIDCONSOLE_BPP8 is not set
The default video console framebuffer size is 16M, and it can be
calculated by:
size = ROUNDUP(width x height x bpp / 8 / 1024 / 1024)
Take 1080p 32bpp as an example:
size = ROUNDUP(1920 x 1080 x 32 / 8 / 1024 / 1024) = 8M
And the following Kconfig option may be set:
/* the framebuffer size of video console */
CONFIG_ROCKCHIP_VIDCONSOLE_MEM_RESERVED_SIZE_MBYTES=8
To confirm the video console is initialized successfully, the logs
may be like:
......
Enable video console mode: resolution[1920x1080] bpp[16]

rockchip: video: reserve memory for fb without bind video driver
The video DM need to bind video driver before relocate in order to
get the size need by video driver, which is fixed in rockchip platform,
we can get it without bind the driver.
With this patch, we don't need to enable the video/display nodes
in pre-reloc, and we can get all these nodes from kernel dtb.
