Impelemented a fix for kernel locks when opening the serial post :
Revisions A->D of the SMC FDC37GT665 Peripherial controller have
a bug in the serial port that is triggered if the FIFO is enabled
while there is a byte in the rx data register resulting in the
rx ready bit being permenantly set.
Removed suspect FPA probing code, instead use the ARM FPE to probe the FPA.
Neatened up the FPE attachment code.
Recognise StrongARM class of cpu.
Updated the fpa instruction bounce handler to expect a 4th argument
when called on an undefined trap to match recent changes made to
undefined handlers.
Add acknowledgement records to the buffer following origin or bounding
box changes.
Removed prototype for strncmp().
Added support for switch mouse reports between absolute and relative
positions.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
a boot string for firmware that can do this, such as the SPARC and
the sun3 models. It is currently silently ignored on all other
hardware now, however. The MD function "boot()" has been changed to
also take a char *.
back on timer 1 interrupts if none is specified.
Only set up timer 1 is the driver is using timer 1 interrupts.
Don't claim the interrupt but allow them to be passed on to other
handlers.
sending of a keyboard reset code. This fixes a problem on some machine
where the reset code ends is a long loop continually trying to reset the
keyboard.
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
Added a new routine kbdreset() to conduct a full keyboard reset.
Added definitions of all keyboard command codes and responces.
Replaced kbd_set_leds() with new function that used kbdcmd().
The keyboard attach function now detects whether a keyboard is
attached or not.
