The video console for DM_VIDEO compliant drivers only understands a very
small number of ANSI sequences. First and foremost it misses the "reverse
video" command, which is used by our own bootmenu command to highlight
the selected entry.
To avoid forcing people to use their imagination when using the
bootmenu, let's just implement the rather simple reverse effect. We need
to store the background colour index for that, so that we can
recalculate both the foreground and background colour pixel values.

When the character to be printed on a DM_VIDEO console is from the
"extended ASCII" range (0x80 - 0xff), it will be treated as a negative
number, as it's declared as a signed char. This leads to negative array
indicies into the glyph bitmap array, and random garbled characters.
Cast the character to an unsigned type to make the index always positive
and avoid an out-of-bounds access.

Currently, HDMI driver doesn't consider minimum and maximum allowed rate
of pll3 (video PLL). It works most of the time, but not always.
Consider monitor with resolution 1920x1200, which has pixel clock rate
of 154 MHz. Current code would determine that pll3 rate has to be set to
154 MHz. However, minimum supported rate is 192 MHz. In this case video
output just won't work.
The reason why the driver is written in the way it is, is that at the
time HDMI PHY and clock configuration wasn't fully understood. But now
we have needed knowledge, so the issue can be fixed.
With this fix, clock configuration routine uses full range (1-16) for
clock divider instead of limited one (1, 2, 4, 11). It also considers
minimum and maximum allowed rate for pll3.

This patch adds support to load 24bpp BMP files on 16bpp displays. This
will be used by the theadorable board. The "old" bmp command did support
this operartion mode and to not break compatibility with the move to
DM_VIDEO, we need to add this support to the "new" bmp code.

This patch moves the Armada XP video / LCD driver to DM_VIDEO. With this

Current EDID detailed timing parser errors out when either

When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.
To mitigate this potential impact, the following changes are
implemented:
- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
drivers that support both statically declared devices and
configuration from device tree
