+ * After this FADT conversion, later ACPICA code will only use the 64-bit "X"
+ * fields of the FADT for all ACPI register addresses.
*
- * "X" fields are optional extensions to the original V1.0 fields. Even if
- * they are present in the structure, they can be optionally not used by
- * setting them to zero. Therefore, we must selectively expand V1.0 fields
- * if the corresponding X field is zero.
+ * The 64-bit "X" fields are optional extensions to the original 32-bit FADT
+ * V1.0 fields. Even if they are present in the FADT, they are optional and
+ * are unused if the BIOS sets them to zero. Therefore, we must copy/expand
+ * 32-bit V1.0 fields if the corresponding X field is zero.
*
- * For ACPI 1.0 FADTs, all address fields are expanded to the corresponding
- * "X" fields.
+ * For ACPI 1.0 FADTs, all 32-bit address fields are expanded to the
+ * corresponding "X" fields in the internal FADT.
*
- * For ACPI 2.0 FADTs, any "X" fields that are NULL are filled in by
- * expanding the corresponding ACPI 1.0 field.
+ * For ACPI 2.0+ FADTs, all valid (non-zero) 32-bit address fields are expanded
+ * to the corresponding 64-bit X fields. For compatibility with other ACPI
+ * implementations, we ignore the 64-bit field if the 32-bit field is valid,
