6dba96d10a Some changes related to the PCI ROM handling.
- 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).

ed669adfd1 - rewrite of the PCI memory management code for the expansion ROM and BIOS area
- store memory type array in the memory object to avoid calling the pci plugin
    frequently. The pci code calls a memory method to change the memory type in
    case the PAM registers are modified.
  - removed now obsolete code and minor cleanups

1f18f5831f - final fix for busmaster DMA transfers from device to memory: new memory method
writePhysicalBlock() replaces the buggy code in iodev.h.
  Calling pageWriteStampTable.decWriteStamp(addr) is required here to make memcpy() work.

fda4d38959 32-bit systems have a problem to allocate large amount of physical memory for Bochs simulation which makes simulation with 4G address space virtually impossible. But in most of the cases when 4G physical address space defined - it is not touched by default on every run so it is possible to allocate only really accessed blocks. This commit made all necessary preparations for it. 2008-04-17 14:39:33 +00:00

a3908d6e86 - moved BX_USE_MEM_SMF to all the other SMF definitions in config.h.in (should
be set to 1, since there is only one address space present)

7b6c2587a9 Now devices could be compiled separatelly from CPU
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...
