moved delay loops to udelay.c renamed -d (debugging) switch to -v (verbose) new switch -d to calibrate delay loop 'Delay' entry for HD44780 back again delay loops will not calibrate automatically, because this will fail with hich CPU load git-svn-id: https://ssl.bulix.org/svn/lcd4linux/trunk@47 3ae390bd-cb1e-0410-b409-cd5a39f66f1f

added BogoMips() to system.c (not used by now, maybe sometimes we can calibrate our delay loop with this value) added delay loop to HD44780 driver. It seems to be quite fast now. Hopefully no compiler will optimize away the delay loop! git-svn-id: https://ssl.bulix.org/svn/lcd4linux/trunk@44 3ae390bd-cb1e-0410-b409-cd5a39f66f1f
