DVT001.001 Node with coreboot exists

Test description

This test aims to verify whether the node with the coreboot exists in the Device Tree.

Test configuration data

  1. FIRMWARE = Dasharo
  2. OPERATING_SYSTEM = Debian 11.0

Test setup

  1. Proceed with the Test cases common documentation section.

Test steps

  1. Power on the DUT.
  2. Boot into the system.
  3. Log into the system by using the proper login and password.

  4. Open a terminal window and run the following command:

    xxd /sys/firmware/devicetree/base/firmware/coreboot/compatible

  5. Note the result.

Expected result

The output of the command should contain information about memory sectors dedicated for coreboot. Example output:

00000000: 636f 7265 626f 6f74 00                   coreboot

DVT002.001 Memory for coreboot is reserved (Ubuntu 22.04)

Test description
