Generally, video drivers request the amount of memory they need for
|
|
|
|
the frame buffer when they are bound, by setting the size field in
|
2021-01-23 18:43:52 +00:00
|
|
|
struct video_uc_plat. That memory is then reserved for use after
|
2020-07-03 03:12:33 +00:00
|
|
|
relocation. But PCI drivers cannot be bound before relocation unless
|
|
|
|
they are mentioned in the devicetree.
|
|
|
|
|
|
|
|
With this value set appropriately, it is possible for PCI video
|
|
|
|
devices to have a framebuffer allocated by U-Boot.
|
|
|
|
|
|
|
|
Note: the framebuffer needs to be large enough to store all pixels at
|
|
|
|
maximum resolution. For example, at 1920 x 1200 with 32 bits per
|
|
|
|
pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed.

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.

This option is useful for targets where, due to alignment
|
|
|
|
restrictions, an improperly aligned BMP image will cause a data
|
|
|
|
abort. If you think you will not have problems with unaligned
|
|
|
|
accesses (for example because your toolchain prevents them)
|
|
|
|
there is no need to set this option.

If this option is set the splash image can be freely positioned
|
|
|
|
on the screen. Environment variable "splashpos" specifies the
|
|
|
|
position as "x,y". If a positive number is given it is used as
|
|
|
|
number of pixel from left/top. If a negative number is given it
|
|
|
|
is used as number of pixel from right/bottom. You can also
|
|
|
|
specify 'm' for centering the image.
|
|
|
|
|
|
|
|
Example:
|
|
|
|
setenv splashpos m,m
|
|
|
|
=> image at center of screen
|
|
|
|
|
|
|
|
setenv splashpos 30,20
|
|
|
|
=> image at x = 30 and y = 20
|
|
|
|
|
|
|
|
setenv splashpos -10,m
|
|
|
|
=> vertically centered image

Use the splash_source.c library. This library provides facilities to
|
|
|
|
declare board specific splash image locations, routines for loading
|
|
|
|
splash image from supported locations, and a way of controlling the
|
|
|
|
selected splash location using the "splashsource" environment
|
|
|
|
variable.
|
|
|
|
|
|
|
|
This CONFIG works as follows:
|
|
|
|
|
|
|
|
- If splashsource is set to a supported location name as defined by
|
|
|
|
board code, use that splash location.
|
|
|
|
- If splashsource is undefined, use the first splash location as
|
|
|
|
default.
|
|
|
|
- If splashsource is set to an unsupported value, do not load a splash
|
|
|
|
screen.
|
|
|
|
|
|
|
|
A splash source location can describe either storage with raw data, a
|
|
|
|
storage formatted with a file system or a FIT image. In case of a
|
|
|
|
filesystem, the splash screen data is loaded as a file. The name of
|
|
|
|
the splash screen file can be controlled with the environment variable
|
|
|
|
"splashfile".
|
|
|
|
|
|
|
|
To enable loading the splash image from a FIT image, CONFIG_FIT must
|
|
|
|
be enabled. The FIT image has to start at the 'offset' field address
|
|
|
|
in the selected splash location. The name of splash image within the
|
|
|
|
FIT shall be specified by the environment variable "splashfile".
|
|
|
|
|
|
|
|
In case the environment variable "splashfile" is not defined the
|
|
|
|
default name 'splash.bmp' will be used.
