Retiring the ANT/JAVA build and removing the older EDK II packages that required ANT/JAVA.
Last Ant/Java build was r7166
Developers requiring the Java/Ant packages should checkout the branch from:

-Module Name:
-
- Dispatcher.c
-
-Abstract:
-
- Tiano DXE Dispatcher.
-
- Step #1 - When a FV protocol is added to the system every driver in the FV
- is added to the mDiscoveredList. The SOR, Before, and After Depex are
- pre-processed as drivers are added to the mDiscoveredList. If an Apriori
- file exists in the FV those drivers are addeded to the
- mScheduledQueue. The mFvHandleList is used to make sure a
- FV is only processed once.
-
- Step #2 - Dispatch. Remove driver from the mScheduledQueue and load and
- start it. After mScheduledQueue is drained check the
- mDiscoveredList to see if any item has a Depex that is ready to
- be placed on the mScheduledQueue.
-
- Step #3 - Adding to the mScheduledQueue requires that you process Before
- and After dependencies. This is done recursively as the call to add
- to the mScheduledQueue checks for Before and recursively adds
- all Befores. It then addes the item that was passed in and then
- processess the After dependecies by recursively calling the routine.
-
- Dispatcher Rules:
- The rules for the dispatcher are in chapter 10 of the DXE CIS. Figure 10-3
- is the state diagram for the DXE dispatcher
-
- Depex - Dependency Expresion.
- SOR - Schedule On Request - Don't schedule if this bit is set.

- Read the Fv and add any driver in the Fv to the mDiscoveredList.The

-Routine Description:
- Given the input key, search for the next matching file in the volume.
-
-Arguments:
- This - Indicates the calling context.
- FileType - FileType is a pointer to a caller allocated
- EFI_FV_FILETYPE. The GetNextFile() API can filter it's
- search for files based on the value of *FileType input.
- A *FileType input of 0 causes GetNextFile() to search for
- files of all types. If a file is found, the file's type
- is returned in *FileType. *FileType is not modified if
- no file is found.
- Key - Key is a pointer to a caller allocated buffer that
- contains implementation specific data that is used to
- track where to begin the search for the next file.
- The size of the buffer must be at least This->KeySize
- bytes long. To reinitialize the search and begin from
- the beginning of the firmware volume, the entire buffer
- must be cleared to zero. Other than clearing the buffer
- to initiate a new search, the caller must not modify the
- data in the buffer between calls to GetNextFile().
- NameGuid - NameGuid is a pointer to a caller allocated EFI_GUID.
- If a file is found, the file's name is returned in
- *NameGuid. *NameGuid is not modified if no file is
- found.
- Attributes - Attributes is a pointer to a caller allocated
- EFI_FV_FILE_ATTRIBUTES. If a file is found, the file's
- attributes are returned in *Attributes. *Attributes is
- not modified if no file is found.
- Size - Size is a pointer to a caller allocated UINTN.
- If a file is found, the file's size is returned in *Size.
- *Size is not modified if no file is found.
-
-Returns:
- EFI_SUCCESS - Successfully find the file.
- EFI_DEVICE_ERROR - Device error.
- EFI_ACCESS_DENIED - Fv could not read.

- Given the input key, search for the next matching file in the volume.
-
-Arguments:
- This - Indicates the calling context.
- FileType - FileType is a pointer to a caller allocated
- EFI_FV_FILETYPE. The GetNextFile() API can filter it's
- search for files based on the value of *FileType input.
- A *FileType input of 0 causes GetNextFile() to search for
- files of all types. If a file is found, the file's type
- is returned in *FileType. *FileType is not modified if
- no file is found.
- Key - Key is a pointer to a caller allocated buffer that
- contains implementation specific data that is used to
- track where to begin the search for the next file.
- The size of the buffer must be at least This->KeySize
- bytes long. To reinitialize the search and begin from
- the beginning of the firmware volume, the entire buffer
- must be cleared to zero. Other than clearing the buffer
- to initiate a new search, the caller must not modify the
- data in the buffer between calls to GetNextFile().
- NameGuid - NameGuid is a pointer to a caller allocated EFI_GUID.
- If a file is found, the file's name is returned in
- *NameGuid. *NameGuid is not modified if no file is
- found.
- Attributes - Attributes is a pointer to a caller allocated
- EFI_FV_FILE_ATTRIBUTES. If a file is found, the file's
- attributes are returned in *Attributes. *Attributes is
- not modified if no file is found.
- Size - Size is a pointer to a caller allocated UINTN.
- If a file is found, the file's size is returned in *Size.
- *Size is not modified if no file is found.
-
-Returns:
- EFI_SUCCESS - Successfully find the file.

-Routine Description:
-
- External function. Initializes the GCD and memory services based on the memory
- descriptor HOBs. This function is responsible for priming the GCD map and the
- memory map, so memory allocations and resource allocations can be made. The first
- part of this function can not depend on any memory services until at least one
- memory descriptor is provided to the memory services. Then the memory services
- can be used to intialize the GCD map.
-
-Arguments:
-
- HobStart - The start address of the HOB
-
- MemoryBaseAddress - Start address of memory region found to init DXE core.
-
- MemoryLength - Length of memory region found to init DXE core.
-
-
-Returns:
-
- EFI_SUCCESS - GCD services successfully initialized.

-
-Abstract:
-
- Section Extraction Protocol implementation.
-
- Stream database is implemented as a linked list of section streams,
- where each stream contains a linked list of children, which may be leaves or
- encapsulations.
-
- Children that are encapsulations generate new stream entries
- when they are created. Streams can also be created by calls to
- SEP->OpenSectionStream().
-
- The database is only created far enough to return the requested data from
- any given stream, or to determine that the requested data is not found.
-
- If a GUIDed encapsulation is encountered, there are three possiblilites.
-
- 1) A support protocol is found, in which the stream is simply processed with
- the support protocol.
-
- 2) A support protocol is not found, but the data is available to be read
- without processing. In this case, the database is built up through the
- recursions to return the data, and a RPN event is set that will enable
- the stream in question to be refreshed if and when the required section
- extraction protocol is published.This insures the AuthenticationStatus
- does not become stale in the cache.
-
- 3) A support protocol is not found, and the data is not available to be read
- without it. This results in EFI_PROTOCOL_ERROR.

- x64 Virtual Memory Management Services in the form of an IA-32 driver.
- Used to establish a 1:1 Virtual to Physical Mapping that is required to
- enter Long Mode (x64 64-bit mode).
-
- While we make a 1:1 mapping (identity mapping) for all physical pages
- we still need to use the MTRR's to ensure that the cachability attirbutes
- for all memory regions is correct.
-
- The basic idea is to use 2MB page table entries where ever possible. If
- more granularity of cachability is required then 4K page tables are used.

- DependencyExpression - Pointer to a dependency expression. The Grammar adheres to
- the BNF described above and is stored in postfix notation.
- Runnable - is True if the driver can be scheduled and False if the driver
- cannot be scheduled. This is the value that the schedulers
- should use for deciding the state of the driver.

- EFI_INVALID_PARAMETER if the dependency expression overflows
