31 * Theory of operation:
32 *
33 * Before relocation each device is bound. The driver for each device must
Simon Glass8a8d24b2020-12-03 16:55:23 -070034 * set the @align and @size values in struct video_uc_plat. This
Simon Glass1acafc72016-01-18 19:52:15 -070035 * information represents the requires size and alignment of the frame buffer
36 * for the device. The values can be an over-estimate but cannot be too
37 * small. The actual values will be suppled (in the same manner) by the bind()
Pali Rohárbd0df822022-03-09 20:46:00 +010038 * method after relocation. Additionally driver can allocate frame buffer
39 * itself by setting plat->base.
Simon Glass1acafc72016-01-18 19:52:15 -070040 *
41 * This information is then picked up by video_reserve() which works out how
42 * much memory is needed for all devices. This is allocated between
43 * gd->video_bottom and gd->video_top.
44 *
45 * After relocation the same process occurs. The driver supplies the same
46 * @size and @align information and this time video_post_bind() checks that
47 * the drivers does not overflow the allocated memory.
48 *
49 * The frame buffer address is actually set (to plat->base) in
50 * video_post_probe(). This function also clears the frame buffer and
51 * allocates a suitable text console device. This can then be used to write
52 * text to the video device.
