The ZyXEL GS1900-8HP is an 8 port gigabit switch with PoE+ support.
There are two versions on the market (v1 & v2) which share similar
specs (same flash size and flash layout, same RAM size, same PoE+ power
envelope) but have a different case and board layout that they each
share with other GS1900 siblings.
The v1 seems to share its PCB and case with non-PoE GS1900-8; as such,
adding support for the GS1900-8 would probably be trivial. The v2 seems
to share its casing and platform with its already supported bigger
brother, the GS1900-10HP - its board looks the same, except for two
holes where the GS1900-10 has its SFP ports.
Like their 10 port sibling, both devices have a dual firmware layout.
Both GS1900-8HP boards have the same 70W PoE+ power budget. In order to
manipulate the PoE+, one needs the rtl83xx-poe package [1].
After careful consideration it was decided to go with separate images
for each version.

Installation
------------
Instructions are identical to those for the GS1900-10HP and apply both
to the GS1900-8HP v1 and v2 as well.
* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs
image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
space bar, and enable the network:
> rtk network on
* Since the GS1900-10HP is a dual-partition device, you want to keep the
OEM firmware on the backup partition for the time being. OpenWrt can
only boot off the first partition anyway (hardcoded in the DTS). To
make sure we are manipulating the first partition, issue the following
commands:
> setsys bootpartition 0
> savesys
* Download the image onto the device and boot from it:
> tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-8hp-v{1,2}-initramfs-kernel.bin
> bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
> sysupgrade /tmp//tmp/openwrt-realtek-generic-zyxel_gs1900-8hp-v{1,2}-squashfs-sysupgrade.bin

For:
- ENH202 v1
- ENS202EXT v1
These boards were committed before it was discovered
that for all Engenius boards with a "failsafe" image,
forcing the failsafe image to load next boot
can be achieved by editing the u-boot environment like:
`fw_setenv rootfs_checksum 0`
So it's not necessary to delete a partition to boot to failsafe image.
Signed-off-by: Michael Pratt <mcpratt@pm.me>
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.

cmake is a dependency of ccache, which means it is build before ccache
is available and hence must be build with non-ccache CC and CXX. It
currently works, because the cmake build system splits the compiler
variable and treats them as multiple compilers to check.
For "ccache gcc" it first tests for "ccache", which always fails,
because ccache is not a compiler by itself, even if it is available, and
then ends up calling "gcc" alone, effectively never using ccache.
Let's make this explicit by forcing the use of non-ccache CC and CXX.

Concerning the revision, the TP-Link page lists v1 and v2 with the
device currently marked as "End of Life". However, the v2 and latest
v1 firmware are byte-identical. Thus, we only need one image for
this device and do not need to include the revision in the image name.

Console is 115200 8N1.
Boot
----
1. Connect to the serial console and connect power.
2. Double-press ESC when prompted
3. Set the fdt address
$ fdt addr $(fdtcontroladdr)
4. Remove the signature node from the control FDT
$ fdt rm /signature
5. Transfer and boot the OpenWrt initramfs image to the device.
Make sure to name the file C0A80114.img and have it reachable at
192.168.1.1/24
$ tftpboot; bootm
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt".
2. Update the bootloader environment.
$ fw_setenv devmode TRUE
$ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
fdt rm /signature; bootubnt"
$ fw_setenv bootcmd "run boot_openwrt"
3. Transfer the OpenWrt sysupgrade image to the device using SCP.
4. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
5. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock6
$ dd if=openwrt.bin of=/dev/mtdblock7
7. Reboot the device. It should boot into OpenWrt.
Below are the original installation instructions prior to the discovery
of "devmode=TRUE". They are not required for installation and are
documentation only.
The bootloader employs signature verification on the FIT image
configurations. This way, booting unauthorized image without patching
the bootloader is not possible. Manually configuring the bootcmd in the
U-Boot envronment won't work, as this is restored to the default value
if modified.
The bootloader is made up of three different parts.
1. The SPL performing early board initialization and providing a XModem
recovery in case the PBL is missing
2. The PBL being the primary U-Boot application and containing the
control FDT. It is LZMA packed with a uImage header.
3. A Ubiquiti standalone U-Boot application providing the main boot
routine as well as their recovery mechanism.
In a perfect world, we would only replace the PBL, as the SPL does not
perform checks on the PBLs integrity. However, as the PBL is in the same
eraseblock as the SPL, we need to at least rewrite both.
The bootloader will only verify integrity in case it has a "signature"
node in it's control device-tree. Renaming the signature node to
something else will prevent this from happening.
Warning: These instructions are based on the firmware intially
shipped with the device and potentially brick your device in a way it
can only be recovered using a SPI flasher.
Only (!) proceed if you understand this!
1. Extract the bootloader from the U-Boot partition using the OpenWrt
initramfs image.
2. Split the bootloader into it's 3 components:
$ dd if=bootloader.bin of=spl.bin bs=1 skip=0 count=45056
$ dd if=bootloader.bin of=pbl.uimage bs=1 skip=45056 count=143360
$ dd if=bootloader.bin of=ubnt.uimage bs=1 skip=188416
3. Strip the uImage header from the PBL
$ dd if=pbl.uimage of=pbl.lzma bs=64 skip=1
4. Decompress the PBL
$ lzma -d pbl.lzma --single-stream
The decompressed PBL sha256sum should be
d8b406c65240d260cf15be5f97f40c1d6d1b6e61ec3abed37bb841c90fcc1235
5. Open the decompressed PBL using your favorite hexeditor. Locate the
control FDT at offset 0x4CED0 (0xD00DFEED). At offset 0x4D5BC, the
label for the signature node is located. Rename the "signature"
string at this offset to "signaturr".
The patched PBL sha256sum should be
d028e374cdb40ba44b6e3cef2e4e8a8c16a3b85eb15d9544d24fdd10eed64c97
6. Compress the patched PBL
$ lzma -z pbl --lzma1=dict=67108864
The resulting pbl.lzma file should have the sha256sum
7ae6118928fa0d0b3fe4ff81abd80ecfd9ba2944cb0f0a462b6ae65913088b42
7. Create the PBL uimage
$ SOURCE_DATE_EPOCH=1607909492 mkimage -A mips -O u-boot -C lzma
-n "U-Boot 2018.03 [UniFi,v1.1.40.71]" -a 84000000 -e 84000000
-T firmware -d pbl.lzma patched_pbl.uimage
The resulting patched_pbl.uimage should have the sha256sum
b90d7fa2dcc6814180d3943530d8d6b0d6a03636113c94e99af34f196d3cf2ce
8. Reassemble the complete bootloader
$ dd if=patched_pbl.uimage of=aligned_pbl.uimage bs=143360 count=1
conv=sync
$ cat spl.bin > patched_uboot.bin
$ cat aligned_pbl.uimage >> patched_uboot.bin
$ cat ubnt.uimage >> patched_uboot.bin
The resulting patched_uboot.bin should have the sha256sum
3e1186f33b88a525687285c2a8b22e8786787b31d4648b8eee66c672222aa76b
9. Transfer your patched bootloader to the device. Also install the
kmod-mtd-rw package using opkg and load it.
$ insmod mtd-rw.ko i_want_a_brick=1
Write the patched bootloader to mtd0
$ mtd write patched_uboot.bin u-boot
10. Erase the kernel1 partition, as the bootloader might otherwise
decide to boot from there.
$ mtd erase kernel1
11. Transfer the OpenWrt sysupgrade image to the device and install
using sysupgrade.
