+
+ 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.

+ Console Splitter Driver. Any Handle that attatched
+ EFI_CONSOLE_IDENTIFIER_PROTOCOL can be bound by this driver.
+
+ So far it works like any other driver by opening a SimpleTextIn and/or
+ SimpleTextOut protocol with EFI_OPEN_PROTOCOL_BY_DRIVER attributes. The big
+ difference is this driver does not layer a protocol on the passed in
+ handle, or construct a child handle like a standard device or bus driver.
+ This driver produces three virtual handles as children, one for console input
+ splitter, one for console output splitter and one for error output splitter.
+ EFI_CONSOLE_SPLIT_PROTOCOL will be attatched onto each virtual handle to
+ identify the splitter type.
+
+ Each virtual handle, that supports both the EFI_CONSOLE_SPLIT_PROTOCOL
+ and Console I/O protocol, will be produced in the driver entry point.
+ The virtual handle are added on driver entry and never removed.
+ Such design ensures sytem function well during none console device situation.

+/*++
+ Routine Description:
+
+ Converts a stream of Unicode characters from a terminal input device into EFI Keys that
+ can be read through the Simple Input Protocol. The table below shows the keyboard
+ input mappings that this function supports. If the ESC sequence listed in one of the
+ columns is presented, then it is translated into the coorespoding EFI Scan Code. If a
+ matching sequence is not found, then the raw key strokes are converted into EFI Keys.
+
+ 2 seconds are allowed for an ESC sequence to be completed. If the ESC sequence is not
+ completed in 2 seconds, then the raw key strokes of the partial ESC sequence are
+ converted into EFI Keys.
+
+ There is one special input sequence that will force the system to reset.
+ This is ESC R ESC r ESC R.
+
+ Arguments:
+
+ TerminaDevice : The terminal device to use to translate raw input into EFI Keys

+ Returns:
