8a094f508c am335x-fb: setup display PLL
The LCDC IP-core an be feed from several clock sources, one of those is
a dedicated DPLL for generating a dividable base-clock for this IP-core.

The TRM specifies the maximum input frequency for the LCCD with 200 MHz,
so we must not exceed this value with the PLL frequency (which can lock
much higher).

This patch tries every combination of multipliers and divisors of the
PLL and the IP-core itself for getting as near as possible the the
requested panel->pxl_clk.

f9d891f0a9 video: Support multiple lines version string display
The calculation of left space for version string is not correct, should
use VIDEO_COLS not VIDEO_LINE_LEN / 2, otherwise we will get larger space
than actual have and cause string to overlay logo picture.

Also current version string display only supports two lines words at max.
This also causes overlay when the LCD pixel column size is not enough.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

703d885c22 dm: video: Add color ANSI escape sequence support
Note that this doesn't differentiate (due to lack of information in
video_priv) between different possible component orders for 32bpp.
But the main user at this point is efi_loader, and GOP expects xBGR
so any video drivers that this is incorrect for already have problems.
(Also, conveniently, this matches what simple-framebuffer bindings
expect for kernels that use the simple-framebuffer DT binding to
take over the bootloader display.)

72719d2f8a video: add STM32 LTDC display controller
The STM32 LTDC display controller provides a parallel digital RGB and
signals for horizontal, vertical synchronization, Pixel Clock and Data
Enable as output to interface directly to a variety of LCD and TFT panels.

The LTDC main features are:
- 24-bit RGB Parallel Pixel Output, Programmable timings & polarity for
  HSync, VSync and Data Enable.
- 2 layers with Blending, Color Keying, Window position & size,
  Dithering, Background color, Color Look-Up Table (CLUT).
- Supported layer color formats: ARGB8888, RGB888, RGB565, ARGB1555,
  ARGB4444, L8 CLUT, AL44 & AL88

This LTDC driver:
- supports: RGB parallel output with timings & polarity, 1 layer
  in RGB565.
- supports but with hard-coded configurations: blending, window
  position & size (crop), background color.
- does not support yet: rgb888, argb8888, 8-bit clut, dithering.

This LTDC driver is compatible with all stm32 platforms with the
LTDC IP and has been tested on stm32 f746-disco board.
