From: Simon Glass Date: Tue, 11 Oct 2022 15:47:17 +0000 (-0600) Subject: test: Move common FIT code into a separate fit_util file X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=a753190a0c544d211faf13a296bd80e830150158;p=u-boot.git test: Move common FIT code into a separate fit_util file To avoid duplicating code, create a new fit_util module which provides various utility functions for FIT. Move this code out from the existing test_fit.py and refactor it with addition parameters. Fix up pylint warnings in the conversion. This involves no functional change.
