- Added new structure bx_pci_bar_t that contains all parameters related to the
PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
BARs and the ROM BAR. Writes to other registers are forwarded to the device
specific PCI write handlers. Removed BAR and ROM BAR handling from the
specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.
- Added support for setting memory write handler to NULL (ROM case).
- Added new PCI device method after_restore_pci_state(). It currently handles
the PCI ROM case only (could be extended).
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.
- Since the pci_read_handler() method is identical in most devices, move it
to the base class to reduce code duplication. Only the 'pcidev' device has
it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.
- ne2k: replaced debugger command 'info ne2k' completely by a new version based
on 'info device' with additional arguments and removed all of the now obsolete
stuff (ne2k device stub, macro for print_info())
- pci: added option 'dump=full' for the debugger command 'info device' to show
the whole PCI config space
- TODO: some other devices could have support for additional options in
debug_dump()
- removed FILE parameter from print_info() (unused - since dbg_printf() doesn't
need it)
- converted tabs to spaces
- TODO: implement 'info device' with optional arguments to get rid of the
print_info() method
