While U-Boot supported graphical output on monitors for ages, the actual user experience on the DM_VIDEO console is somewhat lacking, especially when UEFI applications use the screen via boot services.
This series fixes some of the shortcomings: - Patch 1 includes a rudimentary cursor output, which so far was completely missing from the (DM_VIDEO) console. - Patches 2-5 add support for larger bitmap fonts, which are helpful on high resolution screens as found on modern laptops, for instance. These also pull in two larger bitmaps fonts from the Linux kernel. - Patches 6-8 fix the display of those fonts when used by UEFI applications, which assume Unicode encoding. Beside the actual mapping function this also adds some EFI selftests, which would need to be verifed manually on the screen.
The last three patches are somewhat less refined, they probably require some more discussion.
Please have a look!
Cheers, Andre
