+ help
+ This option provides the packing() helper function, which permits
+ converting bitfields between a CPU-usable representation and a
+ memory representation that can have any combination of these quirks:
+ - Is little endian (bytes are reversed within a 32-bit group)
+ - The least-significant 32-bit word comes first (within a 64-bit
+ group)
+ - The most significant bit of a byte is at its right (bit 0 of a
+ register description is numerically 2^7).
+ Drivers may use these helpers to match the bit indices as described
+ in the data sheets of the peripherals they are in control of.
+
+ When in doubt, say N.
