Subject: test/py: tpm2: Skip tpm pytest based on env variable
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=8870daaa25feee6ab73ec2e52f731a19131cc314;p=u-boot.git

test/py: tpm2: Skip tpm pytest based on env variable

Tpm test cases relies on tpm device setup. Provide an environment
variable "env__tpm_device_test_skip = True" to skip the test case
if tpm device is not present.
Only needed will have to add variable to the py-test framework.
Test runs successfully even this variable is absent.
