ALFA Network Quad-E4G is a universal Wi-Fi/4G platform, which offers
three miniPCIe (PCIe, USB 2.0, SIM) and a single M.2 B-key (dual-SIM,
USB 3.0) slots, RTC and five Gigabit Ethernet ports with PoE support.
Specification:
- MT7621A (880 MHz)
- 256/512 MB of RAM (DDR3)
- 16/32+ MB of FLASH (SPI NOR)
- optional second SPI flash (8-pin WSON/SOIC)
- 1x microSD (SDXC) flash card reader
- 5x 10/100/100 Mbps Ethernet, with passive PoE support (24 V) in LAN1
- optional 802.3at/af PoE module for WAN
- 3x miniPCIe slot (with PCIe and USB 2.0 buses, micro SIM and 5 V)
- 1x M.2/NGFF B-key 3042 (USB 3.0/2.0, mini + micro SIM)
- RTC (TI BQ32002, I2C bus) with backup battery (CR2032)
- external hardware watchdog (EM Microelectronic EM6324)
- 1x USB 2.0 Type-A
- 1x micro USB Type-B for system serial console (Holtek HT42B534)
- 11x LED (5 for Ethernet, 5 driven by GPIO, 1x power indicator)
- 3x button (reset, user1, user2)
- 1x I2C (4-pin, 2.54 mm pitch) header on PCB
- 4x SIM (6-pin, 2.00 mm pitch) headers on PCB
- 2x UART2/3 (4-pin, 2.54 mm pitch) headers on PCB
- 1x mechanical power switch
- 1x DC jack with lock (24 V)
Other:
- U-Boot selects default SIM slot, based on value of 'default_sim' env
variable: '1' or unset -> SIM1 (mini), '2' -> SIM2 (micro). This board
has additional logic circuit for M.2 SIM switching. The 'sim-select'
will work only if both SIM slots are occupied. Otherwise, always slot
with SIM inside is selected, no matter 'sim-select' value.
- U-Boot enables power in all three miniPCIe and M.2 slots before
loading the kernel
- this board supports 'dual image' feature (controlled by 'dual_image'
U-Boot environment variable)
- all three miniPCIe slots have additional 5 V supply on pins 47 and 49
- the board allows to install up to two oversized miniPCIe cards (vendor
has dedicated MediaTek MT7615N/D cards for this board)
- this board has additional logic circuit controlling PERSTn pins inside
miniPCIe slots. By default, PERSTn (GPIO19) is routed to all miniPCIe
slots but setting GPIO22 to high allows PERSTn control per slot, using
GPIO23-25 (value is inverted)
You can use the 'sysupgrade' image directly in vendor firmware which is
based on OpenWrt (make sure to not preserve settings - use 'sysupgrade
-n -F ...' command). Alternatively, use web recovery mode in U-Boot:
1. Power the device with reset button pressed, the modem LED will start
blinking slowly and after ~3 seconds, when it starts blinking faster,
you can release the button.
2. Setup static IP 192.168.1.2/24 on your PC.
3. Go to 192.168.1.1 in browser and upload 'sysupgrade' image.

This replaces all uses of $(cat /sys/class/ieee80211/phyX/macaddress)
by retrieval from the proper flash locations. This will make
02_network independent of WiFi setup again.

- remove WAN port index
- load WAN MAC address directly from the flash
- provide label MAC address
- increase flash's SPI frequency to 80MHz
- add mt76 led nodes to make WiFi LEDs work
- drop unnecessary pinmux groups
The factory partition scheme for MAC addresses (verified on both devices):
0x4 : WiFi 2.4GHz (label_mac-9)
0x28 : unused
0x2e : WAN (label_mac)
0x8004: WiFi 5GHz (label_mac-5)
0xe000: LAN (label_mac-1)
0xe006: unused
By improving flash speed,
`time dd if=/dev/mtdblock3 of=/dev/null bs=64k`
has been reduced from 14.51s to 3.11s.

So far, MAC address assignment in ramips has contained a default
case, which defined wan_mac = eth0 + 1 for _every_ device not
having an explicit case there.
This is not desirable, as many device supporters will just not
care or know about this definition, so another MAC address will be
introduced by accident. In some cases the wan_mac is assigned
although it is not needed, in other cases even addresses not
dedicated to the device will be used (e.g. wan_mac actually is
eth0 - 1, but during support nobody cared, so eth0 + 1 is used now,
which might actually belong to another device ...).
Thus, in this PR the former default case is converted to an
explicit case. This one comprises all devices not being accounted
for by other cases, reduced by those not having wan at all.
The big number of entries for this node might be another indication
that many of them wouldn't actually be there if there hadn't been
default wan_mac setup.
In exchange, the current "do nothing" case can be removed, as it
will be the new default case.
The devices being put in the newly created explicit case were
determined as follows:
1. Create a list of all devices based on the DTS files.
2. Remove all devices already having an explicit entry setting
their address.
3. Remove all devices that only have lan set up in the first part
of 02_network:

This patch does the following:
1. remove u-boot-env partition
Stock bootloader saves env variables at 0x80000 in flash,
and there is nothing stored at 0x30000.
By merging the partition "u-boot-env" with "u-boot",
the partition table becomes the same as used in stock firmware:
00000000-00080000: "Bootloader"
00080000-00100000: "Config"
00100000-00140000: "Factory"
00140000-07f80000: "Kernel"
2. fix LAN/WAN MAC addresses and provide label MAC address
Ethernet MAC addresses are stored in factory partition at:
0xe000: LAN (label_mac)
0xe006: WAN (label_mac+1)
3. fix LAN port order
WF-2881 LAN ports are in reverse order of switch ports.
4. fix WiFi LEDs
mt76 led nodes are added to make WiFi LEDs work.
On top of this, mt76 node names are changed to more generic ones,
and compatible strings are also added.
5. fix pinmux groups
uart3 and uart2 pins are used as button and led, but jtag pins are not.

While most of the target's contents are split into subtargets, the
base-files are maintained for the target as a whole.
However, OpenWrt already implements a mechanism that will use (and
even prefer) files in the subtargets' directories. This can be
exploited to make several scripts subtarget-specific and thus save
some space.
In certain cases, keeping files in parent (=target) base-files was
more convenient, and thus no splitting was performed for those.
Note that this will increase overall code lines, but reduce code
per subtarget.
base-files ipk size reduction:
master (mt7621) 60958 B
split (mt7620) 46358 B (- 14.3 kiB)
split (mt7621) 48759 B (- 11.9 kiB)
