Add format_version class attribute to TargetInfo to track format
changes. This is checked when deserializing from POD to catch format
changes between cached and obtained TargetInfo's.
- Add copyright headers to files that did not already have them
- Update the year to the last year the file was modified in files with
existing headers.
Add hostid entry, as reported by busybox's hostid applet, to TargetInfo.
This is intended to be a "unique 32-bit identifier for the current
machine". In practice, it may not be set, or may be generated from
something like an IP address, so may not be unique. However, if set, it
is still likely to be more unique than kernel/os version so may be worth
recording.
Replace Target.cpuinfo, which contained parsed contents of
/proc/cpuinfo, with a list of more comprehensive CpuInfo objects which
include cpufreq and cpuidle information as well.
Fix TargetInfo.from_pod(). As part of creating the POD, some of devlib's
classes such as Cpuinfo, get serialized. Since they are from devlib,
they do not implement WA's serialization interface, and are instead
serialized by extracting their internal structures. They are then not
deserialized properly, since their __init__'s expect text rather than
parsed structures.
This implements deserialization functions for these classes which
initialize them properly from TargetInfo POD.
Changing the way target descriptions work from a static mapping to
something that is dynamically generated and is extensible via plugins.
Also moving core target implementation stuff under "framework".
