We are currently using a very rudimentary graphics features attached
to U-Boot. It can only display bitmap images. We use this in Chromium
to composite a display for the various screens we need to display in
U-Boot. Unfortunately the graphics screens get quite large when using
multiple languages since they are pre-rendered.
Is there any interest in a simply graphics library in U-Boot, that can
display things on the screen? We already have bitmap support, but
could perhaps add outline font support (e.g. freetype) as well. This
might allow display of simple boot menus or booting information. A
board could create a structure containing a list of things to display
(text, bitmaps) and pass it to the graphics library for rendering
using existing functions and the new font support.
This sounds like a nice feature. Initially. Then I start wondering
if this really belongs into a boot loader. Instead of doing fancy
graphics stuff, we should IMO rather focus on booting the OS of your
choice really fast, and let this do the fancy GUIs. Or?
Yes. Sounds nice at first, but there will be no end of features people
would want afterwards. Next will be video tutorials and fancy sound. ;)
And I think too that all this can be handled by adding a kernel (e.g.
with integrated minimal initramfs) to u-boot. At least that is how I
have handled such in the past.
Regards,
Alexander
