There are three register areas which contain information about the SoC version and revision: - the assist registers contain the SoC's "major version" which encodes the SoC generation and part number. this is available on Meson6, Meson8 and Meson8b SoCs. - the bootrom register contains at least the SoCs "misc version". this is avilable on Meson6, Meson8 and Meson8b - the analog top registers contain information about the SoC revision. this is only available on Meson8 and Meson8b Not much else is currently known about these registers.

Amlogic Meson6/Meson8/Meson8b bootrom:
|
|
--------------------------------------
|
|
|
|
The bootrom register area can be used to access SoC specific
|
|
information, such as the "misc version".
|
|
|
|
Required properties:
|
|
- reg: the register range of the bootrom registers
|
|
- compatible: should be "amlogic,meson-mx-bootrom" along with "syscon"
|
|
|
|
|
|
Example:
|
|
|
|
bootrom: bootrom@d9040000 {
|
|
compatible = "amlogic,meson-mx-bootrom", "syscon";
|
|
reg = <0xd9040000 0x10000>;
|
|
};
