| * 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 "hardwaremain". 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. |
