From af20d9d03bbe080fd9b27024acf5fca7bec15e4f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 7 Nov 2022 23:39:52 +0100 Subject: [PATCH] kernel: split out mtd hack for CONFIG_FIT_PARTITION + rootfs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This is some hack on top of our old hack. Use separated patch for it so it's easier to understand and actually possible to describe. We should ideally get rid of this (and we actually did with kernels 5.15+).
