53  * struct video_priv - Device information used by the video uclass

71  * @cmap:	Colour map for 8-bit-per-pixel displays

104  * video_reserve() - Reserve frame-buffer memory for video devices
109  * a size and position for each frame buffer as part of the pre-relocation
110  * process of determining the post-relocation memory layout.
112  * gd->video_top is set to the initial value of *@addrp and gd->video_bottom
113  * is set to the final value.
115  * @addrp:	On entry, the top of available memory. On exit, the new top,
122  * video_clear() - Clear a device's frame buffer to background color.
130  * video_sync() - Sync a device's frame buffer with its hardware
133  * function syncs these up so that the current contents of the U-Boot frame
143  * video_sync_all() - Sync all devices' frame buffers with there hardware
150  * video_bmp_display() - Display a BMP file
155  * @y:		Y position in pixels from the top
159  *		- if a coordinate is 0x7fff then the image will be centred in
161  *		- if a coordinate is -ve then it will be offset to the
162  *		  left/top of the centre by that many pixels
163  *		- if a coordinate is positive it will be used unchnaged.
164  * @return 0 if OK, -ve on error
170  * video_get_xsize() - Get the width of the display in pixels
178  * video_get_ysize() - Get the height of the display in pixels
186  * Set whether we need to flush the dcache when changing the image. This
189  * @param flush		non-zero to flush cache after update, 0 to skip
194  * Set default colors and attributes

248  * @param row	Row to place cursor (0 = top line)
265  * video_get_info_str() - obtain a board string: type, speed, etc.
