This patchset modifies SeaBIOS source code to be able to build a firmware for the PA-RISC CPU architecture. This firmware can then be used to boot a virtual PA-RISC machine with PA-Linux and HP/UX on QEMU.
Where possible existing SeaBIOS drivers and infrastructure is reused. Since PA-RISC is native 32/64-Bit, the various segment accessors are not needed and replaced by simple variable accesses.
Helge Deller (31): Add config option for PA-RISC arch biosvar.h: Add accessors for various BIOS data areas Drivers: Use get_bda_ptr() BDA accessor byteorder.h: Add endianess conversion functions farptr.h: Add FLATPTR* accessor functions for parisc font.c: Disable built-in x86 font on parisc paravirt.h: Add PORT_QEMU_CFG_CTL for parisc pciinit.c: Initialize PA-RISC Dino PCI chip shadow.c: Compile int3 inline assembly on x86 only Add portaddr_t typedef to specify I/O port addresses ata.c: Allow to boot on PA-RISC ata.h: Add ATA IDE port addresses for PA-RISC blockcmd.c: Prevent unaligned access crash on PA-RISC scsi: Add fields for specifying target and lun of SCSI devices lsi-scsi.c: Convert SCSI script to little endian pci.c: Add PCI ports for PA-RISC and access PCI bus in little-endian rtc.h: Add CMOS/RTC addresses for PA-RISC serialio.h: Add serial port adresses for PA-RISC malloc.c: Implement a PA-RISC specific malloc() output.c: Add PA-RISC specific output behaviour output.c: Make printf() capable to print 64bit int values romfile.c: return values are returned as little-endian sercon.c: Use SEROFF_IIR constant stacks.h: Provide replacement for thread functions when !CONFIG_THREADS version.c: Mark version strings const x86.h: Provide replacement functions for PA-RISC parisc: Add PA-RISC related code string.c: reimplement mem*_far() functions for PA-RISC boot.c: Add boot disc chooser for PA-RISC block.c: Allow PA-RISC to boot from ATA drives ata.c: Add missing endianess conversion functions
