9bd54cc380 Some work on the i440BX chipset AGP support in the Bochs BIOS. 
- rombios.c: return maximum bus number #1 for i440BX.
- Now using different i/o and memory base address regions for PCI and AGP.
- Added some init code for the i440BX PCI/AGP bridge.
- Some code cleanups.

92ce5c3846 Moved PIR table modification for the i440BX chipset from the memory code to the

e781a8f998 Some PCI IRQ roouting changes for i440BX chipset support. 
- Bochs BIOS: Improved calculating PCI slot number from device number to handle
  the i440BX case correctly.
- Memory code: Detect and modify the PCI IRQ roouting table of the Bochs BIOS
  for the i440BX chipset (TODO: this could be done by the BIOS itself after
  copying to shadow RAM).

69be05b2b5 Started preparing the Bochs BIOS for i440BX chipset support. 
- Added symbols for the i440BX host bridge device ID.
- Probe and search for devices on PCI bus #1 (AGP).
- Set up memory and i/o regions only for header type 0.
- Set AGP aperture size to 64 MB.
- TODO: PCI IRQ routing, i440BX specific register setup.

776e8270f6 Started preparing Bochs BIOS for the sector size option. 
- Function ata_cmd_data_io: using fixed block size 512 only for 'identify'
  commands. For read/write commands the hard disk sector size must be used.
- Take account of sector size when calculating hard disk size in MBytes (TODO:
  calculation is not correct for not yet existing very big disks).
- updated comment.

82f45f262a Small addition for the plug&play BIOS stub: added support for function 0x0000 
(currently returning 0 for number of device nodes).

56a7b11ab5 Align PCI memory regions at 64k boundary to make Bochs memory handlers work 
correctly (registering small MMIO regions of USB controllers could fail otherwise).

5a1cd21ca9 - added PCI ROM support to the Bochs BIOS (works with both pcivga and cirrus) 
- scan for VGABIOS ROM after rombios32 init
  - copy PCI ROM to shadow RAM at 0xc0000 and enable it
  - NOTE: this feature does not work with BIOS-bochs-legacy, so we should recommend to use the
    default BIOS for PCI display adapters
  - TODO: load VGABIOS ROM from the vga code instead of main.cc if PCI is disabled
