Reading Processor Variant and Fusemap from the console

We are using the DART 6UL board from Varascite and their Yocto-generated 4.1.15 distribution. I have the following questions:

 

  1. Is there a way to read the processor variant (G0, G1, etc.), e.g., from the /proc file system (from the console)?
  2. How do you read the fuse map from the console? We want to read fuse map location 0x430, bits 21:20, "TAMPER_PIN_DISABLE[1:0]" (from the imx6 applications processor reference manual).

 

Namely I want to find out if the tamper inputs have been fused so that they cannot be used as GPIO outputs.

 

Thanks in advance for any pointers.
