Inspired by Andy Shevchenko's proposal to use get_unaligned_leXX(). The whole one time programable memory is treated as a single 64bit little endian value. Thus we can avoid a lot of messy handling of fields overlapping byte boundaries by just loading and manipulating it as an __le64 converted to a u64. That lets us just use FIELD_GET() and GENMASK() to extract the values desired. Note only build tested. We need to use GENMASK_ULL and %llX formatters to account for the larger types used in computing the various fields.
