From b3770eaca39f223faecfcc0d169a1bb2f6f9464a Mon Sep 17 00:00:00 2001 From: Jeff Kletsky Date: Wed, 10 Apr 2019 08:28:01 -0700 Subject: mtd: base-files: Unify dual-firmware devices (Linksys) Consistently handle boot-count reset and upgrade across ipq40xx, ipq806x, kirkwood, mvebu Dual-firmware devices often utilize a specific MTD partition to record the number of times the boot loader has initiated boot. Most of these devices are NAND, typically with a 2k erase size. When this code was ported to the ipq40xx platform, the device in hand used NOR for this partition, with a 16-byte "record" size. As the implementation of `mtd resetbc` is by-platform, the hard-coded nature of this change prevented proper operation of a NAND-based device. * Unified the "NOR" variant with the rest of the Linksys variants * Added logging to indicate success and failure * Provided a meaningful return value for scripting * "Protected" the use of `mtd resetbc` in start-up scripts so that failure does not end the boot sequence * Moved Linksys-specific actions into common `/etc/init.d/bootcount` For upgrade, these devices need to determine which partition to flash, as well as set certain U-Boot envirnment variables to change the next boot to the newly flashed version. * Moved upgrade-related environment changes out of bootcount * Combined multiple flashes of environment into single one * Current-partition detection now handles absence of `boot_part` Runtime-tested: Linksys EA8300 Signed-off-by: Jeff Kletsky Signed-off-by: Christian Lamparter [checkpatch.pl fixes, traded split strings for 80+ chars per line] --- .../linux/ipq40xx/base-files/etc/init.d/bootcount | 3 ++ .../base-files/etc/init.d/zlinksys_recovery | 34 ------------ .../ipq40xx/base-files/lib/upgrade/linksys.sh | 61 +++++++++++++++------- .../linux/ipq806x/base-files/etc/init.d/bootcount | 13 +++++ .../ipq806x/base-files/etc/init.d/linksys_recovery | 19 ------- .../ipq806x/base-files/lib/upgrade/linksys.sh | 57 +++++++++++++------- .../linux/kirkwood/base-files/etc/init.d/bootcount | 14 +++++ .../base-files/etc/init.d/linksys_recovery | 19 ------- .../kirkwood/base-files/lib/upgrade/linksys.sh | 52 ++++++++++++------ target/linux/mvebu/base-files/etc/init.d/bootcount | 18 +++++++ .../mvebu/base-files/etc/init.d/linksys_recovery | 20 ------- .../linux/mvebu/base-files/lib/upgrade/linksys.sh | 53 +++++++++++++------ 12 files changed, 202 insertions(+), 161 deletions(-) delete mode 100755 target/linux/ipq40xx/base-files/etc/init.d/zlinksys_recovery create mode 100755 target/linux/ipq806x/base-files/etc/init.d/bootcount delete mode 100755 target/linux/ipq806x/base-files/etc/init.d/linksys_recovery create mode 100755 target/linux/kirkwood/base-files/etc/init.d/bootcount delete mode 100755 target/linux/kirkwood/base-files/etc/init.d/linksys_recovery create mode 100755 target/linux/mvebu/base-files/etc/init.d/bootcount delete mode 100755 target/linux/mvebu/base-files/etc/init.d/linksys_recovery (limited to 'target/linux') diff --git a/target/linux/ipq40xx/base-files/etc/init.d/bootcount b/target/linux/ipq40xx/base-files/etc/init.d/bootcount index 604f88c396..abde12412a 100755 --- a/target/linux/ipq40xx/base-files/etc/init.d/bootcount +++ b/target/linux/ipq40xx/base-files/etc/init.d/bootcount @@ -10,5 +10,8 @@ start() { [ -n "$(fw_printenv bootcount changed 2>/dev/null)" ] &&\ echo -e "bootcount\nchanged\n" | /usr/sbin/fw_setenv -s - ;; + linksys,ea6350v3) + mtd resetbc s_env || true + ;; esac } diff --git a/target/linux/ipq40xx/base-files/etc/init.d/zlinksys_recovery b/target/linux/ipq40xx/base-files/etc/init.d/zlinksys_recovery deleted file mode 100755 index ac6533e3fe..0000000000 --- a/target/linux/ipq40xx/base-files/etc/init.d/zlinksys_recovery +++ /dev/null @@ -1,34 +0,0 @@ -#!/bin/sh /etc/rc.common -# -# This script sets auto_recovery to "yes" and resets the boot counter to 0. -# As a golden rule, this should be the latest script to run at boot.
