40 * In order to examine non-volatile sector lock state of AMD-style flash
41 * chips, we need to know how their sectors are grouped for the purpose
42 * of locking: aggregation of sectors into groups that can only be locked
43 * or unlocked as a unit, and also grouping into independent-read partitions
44 * where each partition needs its own Autoselect sequence.
