This allows loading modules with large memory requirements, recently needed
while testing on armvirt/32. Past forum discussions [1] and bug reports [2]
also raised this and the ipq806x target already set it in response [3].
Given this increases kernel image size by only ~1KB, is generally useful on
multi-platform kernels, and enabled by default on upstream arm32 Linux, add
it to the generic config.
The setting has similar utility on arm64, is a requirement for KASLR, and
already enabled on most OpenWrt aarch64 targets, so pull this into the
top-level generic config.

The router boots BL2 which than loads FIP (u-boot).
U-boot has hardcoded a command to always launch Zloader "mtd read zloader 0x46000000" and than "bootm". Bootargs are deactivated.
Zloader is the zyxel booloader which allow to dual-boot ubi or ubi2, by default access to zloader is blocked.
Too zloader checks that the firmware contains a particolar file called zyfwinfo.

Installation
------------
Keep in mind that openwrt can only run on the UBI partition, the openwrt firmware is not able to understand the zloader bootargs.
The procedure allows restoring the UBI partition with the Zyxel firmware and retains all the OEM functionalities.
1. Unlock Zloader (this will allow to swap manually between partitions UBI and UBI2):
- Attach a usb-ttl adapter to your computer and boot the router.
- While the router is booting at some point you will read the following: `Please press Enter to activate this console.`
- As soon as you read that press enter, type root and than press enter again (just do it, don't care about the logs scrolling).
- Most likely the router is still printing the boot log, leave it boot until it stops.
- If everything went ok you should have full root access "root@EX5601-T0:/#".
- Type the following command and press enter: "fw_setenv EngDebugFlag 0x1".
- Reboot the router.
- As soon as you read `Hit any key to stop autoboot:` press Enter.
- If everything went ok you should have the following prompt: "ZHAL>".
- You have successfully unlocked zloader access, this procedure must be done only once.
2. Check the current active partition:
- Boot the router and repeat the steps above to gain root access.
- Type the following command to check the current active image: "cat /proc/cmdline".
- If `rootubi=ubi` it means that the active partition is `mtd6`
- If `rootubi=ubi2` it means that the active partition is `mtd7`
- As mentioned earlier we need to flash openwrt into ubi/mtd6 and never overwrite ubi2/mtd7 to be able to fully roll-back.
- To activate and boot from mtd7 (ubi2) enter into ZHAL> command prompt and type the following commands:
atbt 1 # unlock write
atsw # swap boot partition
atsr # reboot the router
- After rebooting check again with "cat /proc/cmdline" that you are correctly booting from mtd7/ubi2
- If yes proceed with the installation guide. If not probably you don't have a firmware into ubi2 or you did something wrong.
3. Flashing:
- Download the sysupgrade file for the router from openwrt, than we need to add the zyfwinfo file into the sysupgrade tar.
Zloader only checks for the magic (which is a fixed value 'EXYZ') and the crc of the file itself (256bytes).
I created a script to create a valid zyfwinfo file but you can use anything that does exactly the same:
https://raw.githubusercontent.com/pameruoso/OpenWRT-Zyxel-EX5601-T0/main/gen_zyfwinfo.sh
- Add the zyfwinfo file into the sysupgrade tar.
- Enter via telnet or ssh into the router with admin credentials
- Enter the following commands to disable the firmware and model checks
"zycli fwidcheck off" and "zycli modelcheck off"
- Open the router web interface and in the update firmware page select the "restore default settings option"
- Select the sysupgrade file and click on upload.
- The router will flash and reboot itself into openwrt from UBI
4. Restoring and going back to Zyxel firmware.
- Use the ZHAL> command line to manually swap the boot parition to UBI2 with the following:
atbt 1 # unlock write
atsw # swap boot partition
atsr # reboot the router
- You will boot again the Zyxel firmware you have into UBI2 and you can flash the zyxel firmware to overwrite the UBI partition and openwrt.
Working features
----------------
3 gbit lan ports
Wifi
Zyxel partitioning for coexistance with Zloader and dual boot.
WAN SFP port (only after exporting pins 57 and 10. gpiobase411)
leds
reset button
serial interface
usb port
lan ethernet 2.5 gbit port (autosense)
wan ethernet 2.5 gbit port (autosense)
Not working
----------------
voip (missing drivers or proper zyxel platform software)
Swapping the wan ethernet/sfp xor port
----------------
The way to swap the wan port between sfp and ethernet is the following:
export the pins 57 and 10.
Pin 57 is used to probe if an sfp is present.
If pin 57 value is 0 it means that an sfp is present into the cage (cat /sys/class/gpio/gpio468/value).
If pin 57 value is 1 it means that no sfp is inserted into the cage.
In conclusion by default both 57 an 10 pins are by default 1, which means that the active port is the ethernet one.
After inserting an SFP pin 57 will become 0 and you have to manually change the value of pin 10 to 0 too.
This is totally scriptable of course.
Leds description
------------
All the leds are working out of the box but the leds managed by the 2 maxlinear phy (phy 5 lan, phy6 wan).
To activate the phy5 led (rj45 ethernet port led on the back of the router) you have to use mdio-tools.
To activate the phy6 led (led on the front of the router for 2.5gbit link) you have to use mdio-tools.
Example:
Set lan5 led to fast blink on 2500/1000, slow blink on 10/100:
mdio mdio-bus mmd 5:30 raw 0x0001 0x33FC
Set wan 2.5gbit led to constant on when wan is 2.5gbit:
mdio mdio-bus mmd 6:30 raw 0x0001 0x0080

Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.
No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.
Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

* RAM: DDR3 512 MiB (Nanya NT5CC256M16ER-EK)
* Flash: SPI-NAND 256 MiB (Toshiba TC58CVG1S3HRAIJ)
* Wi-Fi 2.4/5 GHz 4T4R:
* 2.4 GHz: MediaTek MT7622BV
* 5 GHz: MediaTek MT7915AN/MT7975AN
* Ethernet: 4x 10/100/1000 Mbps LAN,
1x 10/100/1000/2500 Mbps WAN (Realtek RTL8221B PHY)
* Switch: MediaTek MT7531AE
* LEDs/Keys: 8/1 (Power, Internet, LAN1, LAN2, LAN3, LAN4,

* UART: Marked J19 on board VCC GND TX RX, beginning from "1". 3.3v,
115200n8
* Power: 12 VDC, 2.5 A
Installation:
* Flash the factory image through the stock web interface, or TFTP to
the bootloader. NMRP can be used to TFTP without opening the case.
* U-Boot allows booting an initramfs image via TFTP as follows:
setenv ipaddr 192.168.1.1
setenv serverip 192.168.1.100
tftpboot openwrt-mediatek-mt7622-netgear_wax206-initramfs-recovery.itb
bootm
Known Limitations:
* The 2.5G WAN port labeled 'wan' only works for speeds up to 1G at the
moment. If connected to a multi-gig port the speed has to be manually
set to 1G/full either for the switch port or in OpenWrt. For example
add the following to /etc/rc.local to set it on boot:
/usr/sbin/ethtool -s wan speed 1000 duplex full
Revert to stock firmware:
* Flash the stock firmware to the bootloader using TFTP/NMRP.

By specifying the flag "denx,fit" for partition "kernel", the kernel
try to find rootfs in the same partition during boot. Reality is that
the placement of rootfs is precisely determined by the name of another
partition -"ubi".
It was also found that on some device (for example devices with NAND
chips), the "Denx search engine" manages to find roots at the end of
partition "kernel", but such partition doesn't exist and is empty
there.
Fix this by removing the "denx,fit" flag from partition "kernel". With
this change the original behavior of searchif rootfs in partition "ubi"
is restored.

This variant uses xiaomi factory u-boot and modified u-boot-env &
bootcmd.
By modifying uboot-env, the xiaomi firmware recovery provided in
the vendor u-boot doesn't work anymore. It's possible to put
u-boot into a state where it refuese to take any serial input.
If the u-boot is in this state, users can't restore their
firmware without taking the flash off the board.
We now have a -stock variant where the vendor u-boot is used in
a way that xiaomi firmware recovery still works, and a -ubootmod
variant where we get rid of all xiaomi components, have more
usable space and no uart console lock. These two should cover all
use cases and we don't need this variant anymore.
Drop this redmi-ax6000 variant. Existing users of this variant
should perform a u-boot mod or restore to the -stock layout.

In this implementation, the flash partition layout is adjusted to avoid
modifying the uboot environment of mtdparts. This ensures that the 30M
ubi_kernel partition remains aligned with the stock ubi partition, and
the kernel volume is placed in it. This allows the stock uboot to boot
from it without changing the mtdparts, which is useful for reverting back
to the stock firmware using Xiaomi Firmware Tools. In actual testing,
modifying mtdparts has been found to break Xiaomi Firmware Tools.
1. use ARTIFACTS to generate initramfs-factory.ubi for easy installation.
2. The NAND flash layout is changed to allow for reverting back to the
stock firmware.
3. Before performing sysupgrade, do some cleanup in platform_pre_upgrade
to ensure a clean installation of OpenWRT.
4. Setup the uboot env to ensure that the system always boot, which can
be helpful for users who may forget to do this before sysupgrade in
the initramfs.
New flash instructions:
1. Gain ssh access. Please refer to:
https://openwrt.org/toh/xiaomi/redmi_ax6000#installation)
2. Check which system current u-boot is loading from:
COMMAND: `cat /proc/cmdline`
sample OUTPUT: `console=ttyS0,115200n1 loglevel=8 firmware=1 uart_en=1`
if firmware=1, current system is ubi1
if firmware=0, current system is ubi0
3. Setup nvram and write the firmware:
If the current system is ubi1, please set it up so that the next time
it will boot from ubi, and write the firmware to ubi:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=0
nvram set flag_last_success=0
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit

```
If the current system is ubi, please set it up so that the next time
it will boot from ubi1, and write the firmware to ubi1:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=1
nvram set flag_last_success=1
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
ubiformat /dev/mtd9 -y -f /tmp/initramfs-factory.ubi
```
4. After rebooting, the system should now boot into the openwrt initramfs.
Flash the squashfs-sysupgrade.bin via using ssh or luci.
```
sysupgrade -n /tmp/squashfs-sysupgrade.bin
```
Done.
For existing users of the Redmi AX6000 running OpenWrt, here are the steps to
switch to this new layout:
1. Flash initramfs-factory.ubi
```
mtd -r -e ubi write /tmp/initramfs-factory.ubi ubi
```
2. After rebooting, the system will boot into the new openwrt-initramfs.
Log in and perform a sysupgrade to complete the process.

Raising the temperatures for passive and active trips. @VA1DER
proposed at issue 9396 to remove passive trip. This commit relates to
his suggestion.
Without this patch. the CPU will be throttled all the way down to 98MHz
if the temperature rises even a degree above the trip point, and it was
further discovered that if the internal temperature of the device is
above the first trip point temperature when it boots then it will start
in a throttled state and even
$ echo disabled > /sys/class/thermal/thermal_zone0/mode
will have no effect.
The patch increases the passive trip point and active cooling map. The
throttling temperature will then be at 77°C and 82°C, which is still a
low enough temperature for ARM devices to not be in the real danger
zone, and gives some operational headroom.
