55  * This table is used to convert an input UUID ascii string to a 16 byte
56  * buffer and the reverse. The table maps a UUID buffer index 0-15 to
57  * the index within the 36-byte UUID string where the associated 2-byte
58  * hex value can be found.
59  *
60  * 36-byte UUID strings are of the form:
61  * aabbccdd-eeff-gghh-iijj-kkllmmnnoopp
62  * Where aa-pp are one byte hex numbers, made up of two hex digits
63  *
64  * Note: This table is basically the inverse of the string-to-offset table
65  * found in the ACPI spec in the description of the ToUUID macro.
