Issue Number 1.6 of the Arm SMC Calling Convention introduces an optional SOC_ID name string. If implemented, point the 'machine' field of the SoC Device Attributes at this string so that it will appear under /sys/bus/soc/devices/soc0/machine. On Arm SMC compliant SoCs, this will allow things like 'lscpu' to eventually get a SoC provider model name from there rather than each tool/utility needing to get a possibly inconsistent, obsolete, or incorrect model/machine name from its own hardcoded model/machine name table.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
