[SeaBIOS] [PATCH 00/31] Add support for PA-RISC CPU target

[Helge Deller]

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
