These files were produced by parsing some linux and/or sigmatel
provided headers and later tweaked by hand or by programs.
Each file describes one or more soc. A soc has a list of devices.
Each device can either be unique or have several copies at
different addresses. Each device has a list of registers which
can either be unique or indexed. Each register can further have
a list of fields. Registers with a SCT variant are also handled.
