mdkinney d3a24ff551 When SOURCE_DEBUG_ENABLE is set, a TimerLib is linked into the SEC Phase to support the Debug Agent and the TimerLib is mapped into read-only ROM/FLASH. 
The TimerLib in the OvmfPkg uses a global variable called mPmba and depends on that global being updated.  This works for modules loaded into memory, but not  XIP modules in ROM/FLASH.

This patch removes the mPmba global variable and instead reads the PIIX4 Power Management Base Address from PCI configuration space when it is needed.  This patch also simplifies the initialization logic in the constructor and introduces #defines to eliminate hard coded values in the function implementations.  According to the PIIX4 documentation, the IO Space enable bit in the PCI Command Register does not have to be set for the Power Management Base Address to be decoded, so that one op has been removed from the constructor.

I have tested this patch with QEMU and verified that the UDK Debugger us functional when SOURCE_DEBUG_ENABLE is set.

I also tested it with RHEL-6.3 guest boot/shutdown, Fedora 18 Alpha XFCE
guest boot/shutdown, and Windows 8 Consumer Preview guest
boot/reboot/shutdown. (RHEL-6.3 host.) I didn't notice any adverse effects.

OptionRomPkg The Driver Binding Protocol Stop() function for the UndiRuntimeDxe is performing actions in the incorrect order. The call to UninstallMultipleProtocolInterfaces() removes all the protocols from the child handle, which means ChildHandleBuffer[Index] is no longer valid. After the call to UninstallMultipleProtocolInterfaces(), ChildHandleBuffer[Index] is used again in a call to CloseProtocol(). The handle is not valid, so CloseProtocol() returns an error and generates an ASSERT(). 2012-10-03 23:49:50 +00:00
