[sir_richard] 47684: [HAL]: Use Bus Handler support for HalFindBusAddressTranslation. Implement HalpContextToBusHandler to support this. Seems to work fine with bootvid (only user). All the HAL's bus functions now use Bus Handlers on Legacy systems. There are still big issues with PCI cards. eVb: PCI-x should work now. More PCI-related HAL patches may follow later.

[HAL]: Use Bus Handler support for HalFindBusAddressTranslation. Implement
HalpContextToBusHandler to support this. Seems to work fine with bootvid (only user).
All the HAL's bus functions now use Bus Handlers on Legacy systems. There are
still big issues with PCI cards.
eVb: PCI-x should work now.
More PCI-related HAL patches may follow later.
