drivers: video: Kconfig: Add configs for enabling video at SPL
Add Kconfigs which enable the video driver and splash screen at SPL stage only and not at u-boot proper. The existing Kconfigs from u-boot proper were not used to make SPL splash screen independent to them.

The video subsystem adds a small amount of overhead to the image.

If this is acceptable and you have a need to use video drivers in
|

SPL, enable this option. It might provide a cleaner interface to

setting up video within SPL, and allows the same drivers to be

|

help
|
||||
Generally, video drivers request the amount of memory they need for
|
||||
the frame buffer when they are bound, by setting the size field in
|
||||
struct video_uc_plat. That memory is then reserved for use after
|
||||
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.

config SPL_SPLASH_SOURCE

bool "Control the source of the splash image at SPL"
|

help
|
||||
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.
