65 * This is the call to AmdInitLate. It is really in the wrong place, conceptually,
66 * but functionally within the coreboot model, this is the best place to make the
67 * call. The logically correct place to call AmdInitLate is after PCI scan is done,
68 * after the decision about S3 resume is made, and before the system tables are
69 * written into RAM. The routine that is responsible for writing the tables is
70 * "write_tables", called near the end of "hardwaremain". There is no platform
71 * specific entry point between the S3 resume decision point and the call to
72 * "write_tables", and the next platform specific entry points are the calls to
73 * the ACPI table write functions. The first of ose would seem to be the right
74 * place, but other table write functions, e.g. the PIRQ table write function, are
75 * called before the ACPI tables are written. This routine is called at the beginning
76 * of each of the write functions called prior to the ACPI write functions, so this
77 * becomes the best place for this call.
