From cff4335245e0d23e27917c6cb8f3e1eefda5bb1e Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Fri, 24 Nov 2023 12:22:27 +0000 Subject: [PATCH] kernel: allow skipping deprecated uImage.FIT partition parser In order to allow gradually migrating the boards currently using the uImage.FIT partition (deprecated/rejected) parser to the new fitblk driver, skip the partition parser code in case the new fitblk driver (which serves the same purpose) is used. As an indicator for the use of the new fitblk driver, check if the /chosen/rootdisk property is present in the Device Tree.
