Ivaylo Ivanov	3b517ba95a	lib: debug: Introduce loglevels + many minor changes Implement 8 loglevels to use with printk: While at it, separate the font in a new "video" directory, which also makes space for a proper video probing implementation. Fill in the font from 32 to 256. Scale the font to render twice as big. Implement dynamic line length detection. Change a few things here and there to follow the linux kernel code style. Add a nice logo. Signed-off-by: Ivaylo Ivanov <ivo.ivanov.ivanov1@gmail.com>	2024-10-10 16:24:20 +03:00
