R Nageswara Sastry Nov. 24, 2021, 7:08 a.m. UTC
Existing test cases determine secureboot state using efi variable, which is
available only on x86 architecture.
Add support for determining secureboot state using device tree property on
PowerPC architecture.

Please replace 'PowerPC' with 'PowerNV'.

Rest looks good.
