tty_unlock is used on all other exits from the function.

Remove all #inclusions of asm/system.h

2012-03-28T17:30:03+00:00

Remove all #inclusions of asm/system.h preparatory to splitting and killing
it.  Performed with the following command:

perl -p -i -e 's!^#\s*include\s*.*\n!!' `grep -Irl '^#\s*include\s*' *`

TTY: amiserial, use tty_port_close_start

2012-03-08T20:50:02+00:00

Again, no need to duplicate the code. Let's use the helper.

Amiserial changes are only free of compilation errors. I have no
access to the hardware.

TTY: amiserial, use tty_port_close_end

2012-03-08T20:50:02+00:00

Hmm, the code was sleeping with interrupts disabled. This was not
good. Fix this by turning interrupts at an appropriate place. (The
race is protected by CLOSING flag.)

After the move, the code is identical to tty_port_close_end, so use
it!

TTY: amiserial, use tty_port_block_til_ready

2012-03-08T20:50:01+00:00

Hmm, 150 lines of duplicated stuff is gone now.

TTY: amiserial, provide carrier helpers

2012-03-08T20:50:01+00:00

This is a preparation for a switch to tty_port_block_til_ready. We
need amiga_carrier_raised and amiga_dtr_rts. The implementation is
taken from startup, shutdown and current block_til_ready.

TTY: amiserial no longer needs serialP

2012-03-08T20:50:01+00:00

amiserial is the last user of serialP.h. Let's move struct
serial_state directly to amiserial and remove serialP crap from
includes. Finally, remove the header from the tree completely.

TTY: amiserial, stop using serial_state->{irq,type,line}

2012-03-08T20:50:01+00:00

* instead of line, use tty->index or iterator...
* irq and type are left unset. So get rid of them.

TTY: amiserial, define local tty_port pointer

2012-03-08T20:50:01+00:00

And use it to make the code more readable.

TTY: amiserial/simserial, use flags from tty_port

2012-03-08T20:30:51+00:00

This changes flags' type to ulong which is appropriate for all the
set/clear_bits performed in the drivers..
