The commented out code is not required, as the comment
indicates.
The purpose of this code seems to be to avoid issues caused
by partially overwriting an existing UBI partition, where some
of the erase counters would be reset but not the unmodified
ones. This problem has been solved in a more generic way by
the UBI EOF marker. This ensures that any old PEBs after the
marker are properly initialized. It is therefore unnecessary
to erase the whole partition before flashing a new OpenWrt
factory image.

The Linksys MR8300 is based on QCA4019 and QCA9888
and provides three, independent radios.
NAND provides two, alternate kernel/firmware images
with fail-over provided by the OEM U-Boot.
Hardware Highlights:
SoC: IPQ4019 at 717 MHz (4 CPUs)
RAM: 512MB RAM
SoC: Qualcomm IPQ4019 at 717 MHz (4 CPUs)
RAM: 512M DDR3
FLASH: 256 MB NAND (Winbond W29N02GV, 8-bit parallel)
ETH: Qualcomm QCA8075 (4x GigE LAN, 1x GigE Internet Ethernet Jacks)
BTN: Reset and WPS
USB: USB3.0, single port on rear with LED
SERIAL: Serial pads internal (unpopulated)
LED: Four status lights on top + USB LED
WIFI1: 2x2:2 QCA4019 2.4 GHz radio on ch. 1-14
WIFI2: 2x2:2 QCA4019 5 GHz radio on ch. 36-64
WIFI3: 2x2:2 QCA9888 5 GHz radio on ch. 100-165
Support is based on the already supported EA8300.
Key differences:
EA8300 has 256MB RAM where MR8300 has 512MB RAM.
MR8300 has a revised top panel LED setup.
Installation:
"Factory" images may be installed directly through the OEM GUI using
URL: https://ip-of-router/fwupdate.html (Typically 192.168.1.1)

When OEM volumes are present in the [alt_]firmware partition,
sysupgrade will write a new kernel, but will fail to write
the root file system. The next boot will hang indefinitely
Waiting for root device /dev/ubiblock0_0...
Modified ipq40xx/base-files/lib/upgrade/linksys.sh
to remove both `squashfs` and `ubifs` if found
on the target firmware partition's UBI device.

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.
