From 6dd727ac24fa36ac3f23e9a5cf6781a7d1c6b797 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= <rafal@milecki.pl> 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=UTF-8 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.
