[PATCH v2 6/6] efi_selftest: Add symbol character selftest

Sat Feb 10 13:46:44 CET 2024
From: Janne Grunau <j at jannau.net>
Draw symbols from code page 437 code points 0x01 - 01f used by UEFI
applications to draw user interfaces using
EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.
Add a simple test to displaying the Konami code using symbols used by
grub2. The output has to be checked manually on the screen for
correctness.
