[OpenBIOS] RFC: Rework of OpenBIOS terminal/console

[Mark Cave-Ayland]

Hi all,

Whilst looking at the possibility of supporting additional graphics 
cards in OpenBIOS, I noticed that there are actually two terminal 
consoles built in: a standards-compliant Forth one in 
forth/device/terminal.fs and a C-based one in 
libopenbios/console_common.c (which is the default).

Some experimentation with the Forth console shows that with some minor 
fixes it can be made to work, and in fact produces better console output 
in many cases because the fb8-* and terminal words are implemented 
correctly.

With this in mind, I'd like to propose switching over to the Forth 
console and removing the C console entirely. Would anyone have any major 
objections to doing this?


ATB,

Mark.
