* This is the call to AmdInitLate. It is really in the wrong place, conceptually,

* after the decision about S3 resume is made, and before the system tables are
* written into RAM. The routine that is responsible for writing the tables is
* "write_tables", called near the end of "main". There is no platform
* specific entry point between the S3 resume decision point and the call to
* "write_tables", and the next platform specific entry points are the calls to
* the ACPI table write functions. The first of ose would seem to be the right
* place, but other table write functions, e.g. the PIRQ table write function, are
* called before the ACPI tables are written. This routine is called at the beginning
* of each of the write functions called prior to the ACPI write functions, so this
* becomes the best place for this call.
