firmware: smccc: Add ARCH_SOC_ID support

2020-07-06T08:48:06Z

SMCCC v1.2 adds a new optional function SMCCC_ARCH_SOC_ID to obtain a SiP defined SoC identification value. Add support for the same. Also using the SoC bus infrastructure, let us expose the platform specific SoC atrributes under sysfs. There are various ways in which it can be represented in shortened form for efficiency and ease of parsing for userspace. The chosen form is described in the ABI document.

base: soc: Add serial_number attribute to soc

2019-08-05T21:56:30Z

Add new attribute named "serial_number" as a standard interface for user space to acquire the serial number of the device. For ST-Ericsson SoCs this is exposed by the cryptically named "soc_id" attribute, but this provides a human readable standardized name for this property.
