| * This table is used to convert an input UUID ascii string to a 16 byte |
| * buffer and the reverse. The table maps a UUID buffer index 0-15 to |
| * the index within the 36-byte UUID string where the associated 2-byte |
| * hex value can be found. |
| * |
| * 36-byte UUID strings are of the form: |
| * aabbccdd-eeff-gghh-iijj-kkllmmnnoopp |
| * Where aa-pp are one byte hex numbers, made up of two hex digits |
| * |
| * Note: This table is basically the inverse of the string-to-offset table |
| * found in the ACPI spec in the description of the ToUUID macro. |
