+/**

+  Returns the next high 32 bits of the platform's monotonic counter.

+

+  The GetNextHighMonotonicCount() function returns the next high 32 bits

+  of the platform's monotonic counter. The platform's monotonic counter is

+  comprised of two 32 bit quantities:  the high 32 bits and the low 32 bits.

+  During boot service time the low 32 bit value is volatile:  it is reset to

+  zero on every system reset and is increased by 1 on every call to GetNextMonotonicCount().

+  The high 32 bit value is non-volatile and is increased by 1 whenever the system resets

+  or whenever the low 32 bit count [returned by GetNextMonoticCount()] overflows.

+  The GetNextMonotonicCount() function is only available at boot services time.

+  If the operating system wishes to extend the platform monotonic counter to runtime,

+  it may do so by utilizing GetNextHighMonotonicCount().  To do this, before calling

+  ExitBootServices() the operating system would call GetNextMonotonicCount() to obtain

+  the current platform monotonic count.  The operating system would then provide an

+  interface that returns the next count by:

+    Adding 1 to the last count.

+    Before the lower 32 bits of the count overflows, call GetNextHighMonotonicCount().

+    This will increase the high 32 bits of the platform's non-volatile portion of the monotonic

+    count by 1.

+

+  This function may only be called at Runtime.

+

+  @param[out]   HighCount	Pointer to returned value.

+

+  @retval EFI_INVALID_PARAMETER If HighCount is NULL.

+  @retval EFI_SUCCESS           Operation is successful.

+  @retval EFI_OUT_OF_RESOURCES  If variable service reports that not enough storage

+                                is available to hold the variable and its data.

+  @retval EFI_DEVICE_ERROR      The variable could not be saved due to a hardware failure.
