0220f8c223 sunxi: display: Implement fallback to ddc probe when hpd fails
There are HDMI displays where hpd pin is not connected, thus
we cannot get it to work unless we specifically set the resolution.

Rework the display probing, so hotplug detect failure causes
fallback to probing ddc for EDID data.

7d121a8ea4 sunxi: use 6MHz PLL_VIDEO step for DE2 for higher resolution LCD
DE2 SoCs can support LCDs up to 1080p (e.g. A64), and 3MHz step won't
let PLL_VIDEO be high enough for them.

Use 6MHz step for PLL_VIDEO when using DE2, to satisfy 1080p LCD.

b29712e941 video: sunxi: de2: fix SimpleFB node creation when DE2 not probed
Sometimes when a monitor without EDID information is plugged, the DE2
won't be probed (because of lack of timing information), but the HDMI
node is probed, thus a SimpleFB node with invalid information will be
populated.

Also detect whether DE2 is probed when creating SimpleFB node.

If compile with support for the efi loader we need to mark the pages

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

These are actually different bits, and since some monitors (Benq BL2420PT)
have modes with different HSYNC and VSYNC polarity, we should set them
independently

30ca20234e sunxi: video: Convert lcdc to use struct display_timing
Video driver for older Allwinner SoCs uses cfb console framework which
in turn uses struct ctfb_res_modes to hold timing informations. However,
DM video framework uses different structure - struct display_timing.

It makes more sense to convert lcdc to use new timing structure because
all new drivers should use DM video framework and older drivers might be
rewritten to use new framework too.
