Append a device specific version trailer used by the stock
firmware upgrade application to validate firmwares.
The trailer contains a list of ZyXEL firmware version
numbers, which includes a four letter hardware identifier.
The stock web UI requires that the current hardware matches
one of the listed versions, and that the version number is
larger than a model specific minimum value. The minimum
version varies between V1.00 and V2.60 for the currently
known GS1900 models. The number is not used anywhere else
to our knowlege, and has no direct relation to the version
info in the u-image header. We can therefore use an
arbitrary value larger than V2.60.
The stock firmware upgrade application will only load and
flash the part of the file specified in the u-image header,
regardless of file size. It can therefore not be used to
flash images with an appended rootfs. There is therefore no
need to include the trailer in other images than the
initramfs. This prevents accidentally bricking by attempts
to flash other images from the stock web UI.
Stock images support all models in the series, listing
all of them in the version trailer. OpenWrt provide model
specific images. We therefore only list the single supported
hardware identifier for each image. This eliminates the risk
of flashing the wrong OpenWrt image from stock web UI.
OpenWrt can be installed from stock firmware in two steps:
1) flash OpenWrt initramfs image from stock web gui
2) boot OpenWrt and sysupgrade to a squasfs image
The OpenWrt squashfs image depends on a static partition
map in the DTS. It can only be installed to the "firmware"
partition. This partition is labeled "RUNTIME1" in u-boot
and in stock firmware, and is referred to as "image 0" in
the stock flash management tool. The OpenWrt initramfs
can be installed and run from either partitions. But if
you want to keep stock irmware in the spare system partition,
then you must make sure stock firmware is installed to the
"RUNTIME2" partition referred to as "image 1" in the stock
web UI. And the initial OpenWrt initramfs must be flashed
to "RUNTIME1"/"image 0".
The stock flash management application supports direct
selection of both which partition to flash and which
partition to boot next. This allows software controlled
"dual-boot" between OpenWrt and stock firmware, without
using console access to u-boot. u-boot use the "bootpartition"
variable stored in the second u-boot environment to select
which of the two system partitions to boot. This variable
is set by the stock flash management application, by direct
user input. It can also be set in OpenWrt using e.g
fw_setsys bootpartition 1
to select "RUNTIME2"/"image 1" as default, assuming a
stock firmware version is installed in that partition.

The stock firmware of the ZyXEL GS1900 series use a non-standard
u-image magic. This is not enforced by the stock u-boot, which is
why we could boot images with the default magic. The flash
management application of the stock firmware will however verify
the magic, and refuse any image with another value.
Convert to vendor-specific value to get flash management support
in stock firmware, including the ability to upgrade to OpenWrt
directly from stock web UI.

dnsmasq v2.83 has a bug in handling duplicate queries which means it may
try to reply using the incorrect network socket. This is especially
noticeable in dual stack environments where replies may be mis-directed to
IPv4 addresses on an IPv6 socket or IPv6 addresses on an IPv4 socket.
This results in system log spam such as:

x86 uses append-metadata, but only for signing and not for the
metadata itself.
Since recently SUPPORTED_DEVICES was assigned with a global value
and is not empty anymore, append-metadata will now actually put
metadata into x86 images. This breaks sysupgrade on x86.
To fix it for the moment, let's just empty SUPPORTED_DEVICES for
this target again.
In the long term, one should either not add metadata to the images
if it is not desired, and/or remove the unintended fwtool check.

FCC ID: A8J-EAP1200H
Engenius EAP1200H is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+
**Specification:**
- QCA9557 SOC
- QCA9882 WLAN PCI card, 5 GHz, 2x2, 26dBm
- AR8035-A PHY RGMII GbE with PoE+ IN
- 40 MHz clock
- 16 MB FLASH MX25L12845EMI-10G
- 2x 64 MB RAM NT5TU32M16FG
- UART at J10 populated
- 4 internal antenna plates (5 dbi, omni-directional)
- 5 LEDs, 1 button (power, eth0, 2G, 5G, WPS) (reset)
**MAC addresses:**
MAC addresses are labeled as ETH, 2.4G, and 5GHz
Only one Vendor MAC address in flash
eth0 ETH *:a2 art 0x0
phy1 2.4G *:a3 ---
phy0 5GHz *:a4 ---
**Serial Access:**
the RX line on the board for UART is shorted to ground by resistor R176
therefore it must be removed to use the console
but it is not necessary to remove to view boot log
optionally, R175 can be replaced with a solder bridge short
the resistors R175 and R176 are next to the UART RX pin at J10
**Installation:**
2 ways to flash factory.bin from OEM:
Method 1: Firmware upgrade page:
OEM webpage at 192.168.1.1
username and password "admin"
Navigate to "Firmware Upgrade" 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 0x9fd70000`
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 brick the device
DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt
ssh into openwrt and run
`fw_setenv rootfs_checksum 0`
reboot, wait 3 minutes
connect to ethernet and navigate to 192.168.1.1/index.htm
select OEM firmware image from Engenius and click upgrade
**TFTP recovery:**
Requires serial console, reset button does nothing
rename initramfs to 'vmlinux-art-ramdisk'
make available on TFTP server at 192.168.1.101
power board, interrupt boot
execute tftpboot and bootm 0x81000000
NOTE: TFTP is not reliable due to bugged bootloader
set MTU to 600 and try many times
**Format of OEM firmware image:**
The OEM software of EAP1200H is a heavily modified version
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-ar71xx-generic-eap1200h-uImage-lzma.bin
openwrt-ar71xx-generic-eap1200h-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.
Newer EnGenius software requires more checks but their script
includes a way to skip them, otherwise the tar must include
a text file with the version and md5sums in a deprecated format.
The OEM upgrade script is at /etc/fwupgrade.sh.
OKLI kernel loader is required because the OEM software
expects the kernel to be no greater than 1536k
and the factory.bin upgrade procedure would otherwise
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 switch between
the SOC and the ethernet port.
For QCA955x series, the PLL registers for eth0 and eth1
can be see in the DTSI as 0x28 and 0x48 respectively.
Therefore the PLL registers can be read from uboot
for each link speed after attempting tftpboot
or another network action using that link speed
with `md 0x18050028 1` and `md 0x18050048 1`.
The clock delay required for RGMII can be applied
at the PHY side, using the at803x driver `phy-mode`.
Therefore the PLL registers for GMAC0
do not need the bits for delay on the MAC side.
This is possible due to fixes in at803x driver
since Linux 5.1 and 5.3

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))
(Though this is not precisely an achievement of this commit.)

The newly added `$(COMMITCOUNT)` varialbe allows automatic versioning
based on the number of Git commits of a package. Replace *tedious to

`$(COMMITCOUNT)`.
Signed-off-by: Paul Spooren <mail@aparcar.org>
The lack of bumped PKG_RELEASE variables is a recurring theme on the
mailing list and in GitHub comments. This costs precious review time,
a rare good within the OpenWrt project.
Instead of relying on a manually set PKG_RELEASE this commit adds a
`commitcount` function that uses the number of Git commits to determine
the release. The function is called via the variables `$(AUTORELEASE)`
or `$(COMMITCOUNT)`. The `PKG_RELEASE` variable can be set to either of
the two.
- $(AUTORELEASE):
Release is automagically set to the number of commits since the last
commit containing either ": update to " or ": bump to ".
Example below:
$ git log packages/foobar/
foobar: fixup file location
foobar: disable docs
foobar: bump to 5.3.2
foobar: fixup copyright
Resulting package name: foobar_5.3.2-3_all.ipk, two package changes
since the last upstream version change, using a 1 based counter.
- $(COMMITCOUNT):
For non-traditional versioning (x.y.z), most prominent `base-files`,
this variable contains the total number of package commits.
The new functionality can also be used by other feeds like packages.git.
In case no build information is available, e.g. when using release
tarballs, the SOURCE_DATE_EPOCH is used to have a reproducible release
identifier.
