Message

This patchset adds a socinfo driver which provides information about
Actions Semi Owl SoCs to user space via sysfs: machine, family, soc_id,
serial_number.

Please note the serial number is currently available only for the S500
SoC variant.

This has been tested on the S500 SoC based RoseapplePi SBC.

Thanks,
Cristi
