From: Roman Yeryomin Date: Fri, 4 May 2018 15:18:51 +0000 (+0300) Subject: gemini: fix hard disk boot on D-Link devices X-Git-Tag: v18.06.0-rc1~266 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ce93b05bf1465b240366000f833e413c0b916125;p=openwrt%2Fstaging%2Fpepe2k.git gemini: fix hard disk boot on D-Link devices Since the D-Link devices boot from hard disk we need to add the following changes to Gemini: - Supply a bootarg in the device tree so we can boot from the right partition (/dev/sda4 on DNS-313) - Disable forced command line in config so the kernel picks up the right bootargs from the device tree - Enable EXT4 in the config as this is used for rootfs else we get nowhere, we cannot load this as a module because, well, it is supposed to be loaded from the root partition (chicken and egg problem). - Enable jbd2 and mbcache (needed by ext4) Also clean out the premature attempts to dynamically modify the command line in the Image makefile: we should pass this with the device tree bootargs instead, it works much better.
