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`

Tested and working:
- USB (requires extra packages)
- LAN Ethernet (Correct MAC-address)
- WAN Ethernet (Correct MAC-address)
- 2.4 GHz WiFi (Correct MAC-address)
- 5 GHz WiFi (Correct MAC-address)
- Factory installation from Web UI
- OpenWRT sysupgrade
- LED
- Reset Button
Need Testing:
- WPS button
Install via Web UI:
- Attach to a LAN port on the router.
- Connect to the Linksys Smart WiFi Page (default 192.168.1.1) and login
- Select the connectivity tab on the left
- In the manual update box on the right
- Select browse, and browse to
openwrt-ipq40xx-linksys_ea6350v3-squashfs-factory.bin
- Click update.
- Read and accept the warning
- The router LED will start blinking. When the router LED goes solid, you
can now navigate to 192.168.1.1 to your new OpenWrt installation.
Sysupgrade:
- Flash the sysupgrade image as usual. Please: try to do a reset everytime
you can (doing it with LuCI is easy and can be done in the same step).
Recovery (Automatic):
- If the device fails to boot after install or upgrade, whilst the unit is
turned on:
1 - Wait 15 seconds
2 - Switch Off and Wait 10 seconds
3 - Switch on
4 - Repeat steps 1 to 3, 3 times then go to 5.
5 - U-boot will have now erased the failed update and switched back to the
last working firmware - you should be able to access your router on
LAN.
Recovery (Manual):
- The steps for manual recovery are the same as the generic u-boot tftp
client method.
Back To Stock:
- Use the generic recovery using the tftp client method to flash the
"civic.img". Also you can strip-and-pad the original image and use
the generic "mtd" method by flashing over the "kernel" partition.
* Just be careful to flash in the partition that the device is currently
booted.
