The Amlogic Meson SoC Secure Monitor implements a call to retrieve an
unique SoC ID starting from the GX Family and all new families.
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 third 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.
- add secure-monitor references for amlogic,meson-gx-ao-secure sections
in dts files of the a1, axg, g12, gx families.


---

Changes V1 -> V2 [1]:
 - create cpu_id structure for socinfo variable
 - create meson_sm_chip_id for result of sm call
 - remove shared functions
 - move from funcs for bit operations to C bit fields

Move common constants and inline functions from meson-gx-socinfo driver
to header file. Create new structures for store meson64 cpu_id and chip_id.

Amlogic SoCs have a SoC information secure-monitor call for SoC type,
package type, revision information and chipid.
This patchs adds support for secure-monitor call decoding and exposing
with the SoC bus infrastructure in addition to the previous SoC
Information driver.

Hi!

Will be fixed in next version with new Kconfig dependencies:

     depends on (ARM64 && ARCH_MESON || COMPILE_TEST) && MESON_SM=y
     default ARCH_MESON && MESON_SM
