From 76423e236475f7fb6ee863f28a18b20f97ccec44 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 24 Mar 2021 18:20:13 +0100 Subject: [PATCH] kernel: create bootfs partition when parsing on BCM4908 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It's helpful for accessing booting data (DTS, kernel, etc.). It has to be used carefully as CFE's JFFS2 support is quite dumb. It doesn't recognize deleted files and has problems handling 0 inode.
