But GX-family chips (e.g. GXB, GXL and newer) supports also 128-bit chip ID. 128-bit chip ID consists 32-bit SoC version and 96-bit OTP data. This is the second attempt to publish data from the Amlogic secure monitor chipid call. After discussions with Neil Armstrong, it was decided to publish the chipid call results through the soc driver. Since soc_device_match cannot wait for the soc driver to load, and the secure monitor calls in turn depend on the sm driver, it was necessary to create a new driver rather than expand an existing one. In the patches, in addition to writing the driver: - convert commonly used structures and functions of the meson-gx-socinfo driver to a header file. - transfer the chipid sm call constants to a header file (perhaps they need renaming?). - add secure-monitor references for amlogic,meson-gx-ao-secure sections in dts files of the a1, axg, g12, gx families.
