The uart node is enabled on all devices except one (GL-USB150 *).

disable it in the first place.
Where the majority of devices is using it, also move the serial0

Regulator support was enabled on all subtargets except for ath79-nand.
With Kernel 5.10, AT803x requires Regulator support, thus enabling on
the complete target, as ath79-nand requires AT803x.
While this is only required on Kernel 5.10, enable it also on 5.4. We

Port device support for Meraki MR12 from the ar71xx target to ath79.
Specifications:
- SoC: AR7242-AH1A CPU
- RAM: 64MiB (NANYA NT5DS32M16DS-5T)
- NOR Flash: 16MiB (MXIC MX25L12845EMI-10G)
- Ethernet: 1 x PoE Gigabit Ethernet Port (SoC MAC + AR8021-BL1E PHY)
- Ethernet: 1 x 100Mbit port (SoC MAC+PHY)
- Wi-Fi: Atheros AR9283-AL1A (2T2R, 11n)
Installation:
1. Requires TFTP server at 192.168.1.101, w/ initramfs & sysupgrade .bins
2. Open shell case
3. Connect a USB->TTL cable to headers furthest from the RF shield
4. Power on the router; connect to U-boot over 115200-baud connection
5. Interrupt U-boot process to boot Openwrt by running:
setenv bootcmd bootm 0xbf0a0000; saveenv;
tftpboot 0c00000 <filename-of-initramfs-kernel>.bin;
bootm 0c00000;
6. Copy sysupgrade image to /tmp on MR12
7. sysupgrade /tmp/<filename-of-sysupgrade>.bin
Notes:
- kmod-owl-loader is still required to load the ART partition into the
driver.
- The manner of storing MAC addresses is updated from ar71xx; it is
at 0x66 of the 'config' partition, where it was discovered that the
OEM firmware stores it. This is set as read-only. If you are
migrating from ar71xx and used the method mentioned above to
upgrade, use kmod-mtd-rw or UCI to add the MAC back in. One more
method for doing this is described below.
- Migrating directly from ar71xx has not been thoroughly tested, but
one method has been used a couple of times with good success,
migrating 18.06.2 to a full image produced as of this commit. Please
note that these instructions are only for experienced users, and/or
those still able to open their device up to flash it via the serial
headers should anything go wrong.
1) Install kmod-mtd-rw and uboot-envtools
2) Run `insmod mtd-rw.ko i_want_a_brick=1`
3) Modify /etc/fw_env.config to point to the u-boot-env partition.
The file /etc/fw_env.config should contain:
# MTD device env offset env size sector size
/dev/mtd1 0x00000 0x10000 0x10000
See https://openwrt.org/docs/techref/bootloader/uboot.config
for more details.
4) Run `fw_printenv` to verify everything is correct, as per the
link above.
5) Run `fw_setenv bootcmd bootm 0xbf0a0000` to set a new boot address.
6) Manually modify /lib/upgrade/common.sh's get_image function:
Change ...
cat "$from" 2>/dev/null | $cmd
... into ...
(
dd if=/dev/zero bs=1 count=$((0x66)) ; # Pad the first 102 bytes
echo -ne '\x00\x18\x0a\x12\x34\x56' ; # Add in MAC address
dd if=/dev/zero bs=1 count=$((0x20000-0x66-0x6)) ; # Pad the rest
cat "$from" 2>/dev/null
) | $cmd
... which, during the upgrade process, will pad the image by
128K of zeroes-plus-MAC-address, in order for the ar71xx's
firmware partition -- which starts at 0xbf080000 -- to be
instead aligned with the ath79 firmware partition, which
starts 128K later at 0xbf0a0000.
7) Copy the sysupgrade image into /tmp, as above
8) Run `sysupgrade -F /tmp/<sysupgrade>.bin`, then wait
Again, this may BRICK YOUR DEVICE, so make *sure* to have your
serial cable handy.

feed the watchdog when decompressing kernel. If the kernel is
LZMA-compressed, it might take too long before watchdog timeout.
So we have to use gzip instead for faster decompressing speed.
For initramfs image, compression is not used because it is bigger

The majority of our targets provide a default value for the variable
SUPPORTED_DEVICES, which is used in images to check against the
compatible on a running device:
SUPPORTED_DEVICES := $(subst _,$(comma),$(1))
At the moment, this is implemented in the Device/Default block of
the individual targets or even subtargets. However, since we
standardized device names and compatible in the recent past, almost
all targets are following the same scheme now:
device/image name: vendor_model
compatible: vendor,model
The equal redundant definitions are a symptom of this process.
Consequently, this patch moves the definition to image.mk making it
a global default. For the few targets not using the scheme above,
SUPPORTED_DEVICES will be defined to a different value in
Device/Default anyway, overwriting the default. In other words:
This change is supposed to be cosmetic.
This can be used as a global measure to get the current compatible
with: $(firstword $(SUPPORTED_DEVICES))

Flashing from serial console
1. Connect serial console (115200 baud)
2. Connect ethernet to a network with a TFTP server, through a
passive PoE injector.
3. Press a key to obtain a u-boot prompt
4. Set your TFTP server's ip address, with:
setenv serverip <tftp-server-address>
5. Set the Bullet AC's ip address, with:
setenv ipaddr <bullet-ac-address>
6. Set the boot file, with:
setenv bootfile <name-of-initramfs-binary-on-tftp-server>
7. Fetch the binary with tftp:
tftpboot
8. Boot the initramfs binary:
bootm
9. From the initramfs, fetch the sysupgrade binary, and flash it with

This moves some of the Engenius boards from generic to tiny:
- EAP350 v1
- ECB350 v1
- ENH202 v1
For these, factory.bin builds are already failing on master
branch because of the unique situation for these boards:
- 8 MB flash
- an extra "failsafe" image for recovery
- TFTP does not work (barely possible with 600 MTU)
- bootloader loads image from a longer flash offset
- 1 eraseblock each needed for OKLI kernel loader and fake rootfs
- using mtd-concat to make use of remaining space...
The manual alternative would be removing the failsafe partition.
However this comes with the risk of extremely difficult recovery
if a flash ever fails because TFTP on the bootloader is bugged.

Installation:
2 ways to flash factory.bin from OEM:
- if you get Failsafe Mode from failed flash:
only use it to flash Original firmware from Engenius
or risk kernel loop or halt which requires serial cable
Method 1: Firmware upgrade page:
OEM webpage at 192.168.10.1
username and password "admin"
Navigate to "Upgrade Firmware" page from left pane
Click Browse and select the factory.bin image
Upload and verify checksum
Click Continue to confirm and wait 3 minutes
Method 2: Serial to load Failsafe webpage:
After connecting to serial console and rebooting...
Interrupt uboot with any key pressed rapidly
execute `run failsafe_boot` OR `bootm 0x9f670000`
wait a minute
connect to ethernet and navigate to
"192.168.1.1/index.htm"
Select the factory.bin image and upload
wait about 3 minutes
Return to OEM:
If you have a serial cable, see Serial Failsafe instructions
otherwise, uboot-env can be used to make uboot load the failsafe image
*DISCLAIMER*
The Failsafe image is unique to Engenius boards.
If the failsafe image is missing or damaged this will not work
DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt
ssh into openwrt and run
`fw_setenv rootfs_checksum 0`

of Openwrt Kamikaze. One of the many modifications
is to the sysupgrade program. Image verification is performed
simply by the successful ungzip and untar of the supplied file
and name check and header verification of the resulting contents.
To form a factory.bin that is accepted by OEM Openwrt build,
the kernel and rootfs must have specific names...
openwrt-senao-eap350-uImage-lzma.bin
openwrt-senao-eap350-root.squashfs
and begin with the respective headers (uImage, squashfs).
Then the files must be tarballed and gzipped.
The resulting binary is actually a tar.gz file in disguise.
This can be verified by using binwalk on the OEM firmware images,
ungzipping then untaring.
The OEM upgrade script is at /etc/fwupgrade.sh
Later models in the EAP series likely have a different platform
and the upgrade and image verification process differs.
OKLI kernel loader is required because the OEM software
expects the kernel to be no greater than 1024k
and the factory.bin upgrade procedure would
overwrite part of the kernel when writing rootfs.
Note on PLL-data cells:
The default PLL register values will not work
because of the external AR8035-A switch between
the SOC and the ethernet PHY chips.
For AR724x series, the PLL register for GMAC0
can be seen in the DTSI as 0x2c.
Therefore the PLL register can be read from uboot
for each link speed after attempting tftpboot
or another network action using that link speed
with `md 0x1805002c 1`.
uboot did not have a good value for 1 GBps
so it was taken from other similar DTS file.
Tested from master, all link speeds functional
