CVS Tags: HEAD 

initial bits of driver for Hitachi HD44780-compatible LCD controllers.
machine dependent part sits in p64lcd.c;
it doesn't initialize LCD properly - missed some timings, i think.

unfortunately, i have fryed my brand-new 16x4 LCD and can't continue work right now..
very sadly, R.I.P :(
