parisc: SEABIOS_HPPA_VERSION 6serial-port-fix-test
New features and fixes:
* Allow "z" instead of "y" in firmware boot menu for german keyboards
* Fixed serial port emulation
Serial ports ttyS0 and ttyS1 were swapped compared to the real hardware.
So, a booting Linux was actually using ttyS1 as serial console, and the
emulated ttyS0 wasn't useable.
With this version you can use e.g.:
-serial mon:stdio -serial /dev/ttyS4
to use emulated ttyS0 in the gueast for console output, and pass ttyS4
from the host to ttyS1 in the guest.
NOTE: This version is incompatible with older qemu versions, since
the serial ports are now swapped.
