parisc: SEABIOS_HPPA_VERSION 6 * Fixed SeaBIOS serial port support. Qemu versions which request a SEABIOS_HPPA_VERSION < 6 have the bug that they use the DINO UART instead of the LASI UART as serial port #0. Staring with SEABIOS_HPPA_VERSION 6 the serial ports are now emulated as on physical hardware, with LASI UART being serial port #0. Compat support is included: DINO UART port will be used for console I/O if it detects that qemu requests a SEABIOS_HPPA_VERSION < 6.
