The Linksys EA8300 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.
Installation:
"Factory" images may be installed directly through the OEM GUI.
Hardware Highlights:
* IPQ4019 at 717 MHz (4 CPUs)
* 256 MB NAND (Winbond W29N02GV, 8-bit parallel)
* 256 MB RAM
* Three, fully-functional radios; `iw phy` reports (FCC/US, -CT):
* 2.4 GHz radio at 30 dBm
* 5 GHz radio on ch. 36-64 at 23 dBm
* 5 GHz radio on ch. 100-144 at 23 dBm (DFS), 149-165 at 30 dBm
#{ managed } <= 16, #{ AP, mesh point } <= 16, #{ IBSS } <= 1
* All two-stream, MCS 0-9
* 4x GigE LAN, 1x GigE Internet Ethernet jacks with port lights
* USB3, single port on rear with LED
* WPS and reset buttons
* Four status lights on top
* Serial pads internal (unpopulated)

Implementation Notes:
The OEM flash layout is preserved at this time with 3 MB kernel and
~69 MB UBIFS for each firmware version. The sysdiag (1 MB) and
syscfg (56 MB) partitions are untouched, available as read-only.
Serial Connectivity:
Serial connectivity is *not* required to flash.
Serial may be accessed by opening the device and connecting
a 3.3-V adapter using 115200, 8n1. U-Boot access is good,
including the ability to load images over TFTP and
either run or flash them.
Looking at the top of the board, from the front of the unit,

Other Notes:
https://wikidevi.com/wiki/Linksys_EA8300 states
FCC docs also cover the Linksys EA8250. According to the
RF Test Report BT BR+EDR, "All models are identical except
for the EA8300 supports 256QAM and the EA8250 disable 256QAM."

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`

[checkpatch.pl fixes, traded split strings for 80+ chars per line]
ALFA Network AP120C-AC is a dual-band ceiling AP, based on Qualcomm
IPQ4018 + QCA8075 platform.
Specification:
- Qualcomm IPQ4018 (717 MHz)
- 256 MB of RAM (DDR3)
- 16 MB (SPI NOR) + 128 MB (SPI NAND) of flash
- 2x Gbps Ethernet, with 802.3af PoE support in one port
- 2T2R 2.4/5 GHz (IPQ4018), with ext. FEMs (QFE1952, QFE1922)
- 3x U.FL connectors
- 1x 1.8 dBi (Bluetooth) and 2x 3/5 dBi dual-band (Wi-Fi) antennas
- Atmel/Microchip AT97SC3205T TPM module (I2C bus)
- TI CC2540 Bluetooth LE module (USB 2.0 bus)
- 4x LED (all driven by GPIO)
- 1x button (reset)
- 1x USB 2.0 (optional, not installed in indoor version)
- DC jack for main power input (12 V)
- UART header available on PCB (2.0 mm pitch)
Flash instruction:
1. This board uses dual-image feature (128 MB NAND is divided into two
64 MB partitions: 'rootfs1' and 'rootfs2').
2. Before update, make sure your device is running firmware no older
than v1.1 (previous versions have incompatible U-Boot).
3. Use 'factory' image in vendor GUI or for sysupgrade tool, without
preserving settings.

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.
