301af2388a video: sandbox: Set a maximum frame-buffer size
If U-Boot starts with the frame buffer set to 16bpp but then runs a test
that uses 32bpp, there is not enough space. Update the driver to use the
maximum possible frame-buffer size, to avoid this.

250e735c69 video: sandbox: Avoid duplicate display windows
When unit tests are run they currently create a new window. Update the
code so that the old one is removed first. This avoids the confusion as to
which one is active.

0fe5e9481e sandbox: video: Support 8bpp depth
At present sandbox only supports 16 and 32bpp depths, since those are the
easy ones with SDL.

We can support other depths by manually converting the pixel formats. Add
support for this, to enable an 8ppp (monochrome) format.

6cdeb323b8 video: stm32: stm32_ltdc: align framebuffer on 2MB
Align the framebuffer size on MMU_SECTION_SIZE in kernel, = max 2MB for
LPAE for armV7, to avoid issue with the simple frame buffer activation,
when U-Boot add a reserved memory in the kernel device tree to preserve
the splash screen until Linux driver initialization.

See Linux documentation for details:
Documentation/devicetree/bindings/display/simple-framebuffer.yaml
