* UUID support functions.

* 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 to_UUID macro.
