This commit adds OpenWrt U-Boot (UBI) layout support for MERCUSYS MR90X
v1.
Stock U-Boot UBI size: 50 MiB
OpenWrt U-boot UBI size: 126 MiB
Install
-------
1. Perform steps 1-14 of the OpenWrt installation guide (use OpenWrt
initramfs-recovery.itb instead of initramfs-kernel.bin at the step 10,
12 and 14). Link: https://openwrt.org/toh/mercusys/mr90x_v1#installation
2. Make backups:
```
cat /dev/mtd0 > /tmp/boot.bin
cat /dev/mtd5 > /tmp/tp_data.bin
```
Copy /tp_data dir content, /tmp/boot.bin and /tmp/tp_data.bin and to
your PC using scp. You can also backup the remaining partititons. Copy
backups to a safe place, they are required for the next steps and stock
firmware recovery.
3. Reboot to OpenWrt initramfs:
```
reboot
```
4. Copy OpenWrt ubi-bl31-uboot.fip, ubi-preloader.bin,
ubi-squashfs-sysupgrade.itb and MT7986_EEPROM.bin, default-mac (from
/tp_data backup) to the /tmp folder of the router using scp.
Recovery
--------
1. Place OpenWrt initramfs-recovery.itb image (with original name) on the
tftp server (IP: 192.168.1.254).
2. Press "reset" button and power on the router. After ~10 sec release the
button.
3. Use OpenWrt initramfs system for recovery.
4. Erase UBI and reboot:
```
mtd erase ubi
reboot
```
5. Open U-Boot web recovery, upload stock firmware image and start
upgrade. Link: http://192.168.1.1
6. Complete steps 1-9 of the OpenWrt installation guide to get root
rights. Link: https://openwrt.org/toh/mercusys/mr90x_v1#installation
7. Upload "tp_data" partition backup (tp_data.bin) to the /tmp folder of
the router using scp.
The device path to the devices changed. Migrate the wifi
configurations from the old path to the new one. This is needed to
migrate Wireless configurations from OpenWrt 23.05 to OpenWrt 24.10.

build: Unconditionally append kmod feed for BuildBot
Recent changes to BuildBot config moved the kmods to a dedicated

both OPKG and APK gets confused if both entry are present.
To fix this, unconditionally append the kmod feed line if
CONFIG_BUILDBOT is enabled.
"ethaddr" is stored into the "u-boot-env" (stock: "Config") partition
and it's quoted with double-quotations, but that format is not supported

MAC address won't be parsed to byte array.

ipq807x: prpl haze & qnap 301w: use the standard eMMC sysupgrade code
Note that the old ad-hoc method did not explicitly align backup data
to 64 KiB boundaries.
Also note that the qnap 301w has a 'rootfs_data' partition in the eMMC

This is why the partition is also ignored in the sysupgrade code and
there is no definition of CI_DATAPART="rootfs_data".
Since the start of the Realtek target OpenWrt works with RTL83XX as the
target architecture. Upstream is using MACH_REALTEK_RTL instead. To
simplify further development align that.
But there is no `libreadline.so` or `libhistory.so` available.
So this happens:
```
root@OpenWRT:~# cat a.c
int main() {
}
root@OpenWRT:~# gcc a.c -lreadline
/usr/bin/ld: cannot find -lreadline: No such file or directory
collect2: error: ld returned 1 exit status
```
Unless, of course, one uses `-l:libreadline.so.8`... But that
doesn't help with binaries that try to dynamically open
`libreadline.so`. I have one of those here (the STklos Scheme
compiler -- I didn't make a PR for it because it's far from
being ready, but one issue is that it does use dlopen to use
readline...)
Another example: when trying to package rlwrap, the build failed
complaining it could not find readline (using `-lreadline`).
It would then be necessary to change rlwrap's `configure.ac`
(and also in all packages that use readline), but it seems
simpler to add the symlinks...

x86: switch config to a tickless kernel
This commit fixes and closes #16313.
Switch the x86 kernel's timer to tickless operation which is
more power efficient since it is not woken up by periodic timer
interrupts when idle. Also add several other options for CPU
idle governors particularly the upstream default for tickless
kernels, CONFIG_CPU_IDLE_GOV_MENU. Without this commit, my AMD
Ryzen 7 5800U can only achieve a minimum core frequency of 1,384
MHz which is over 3x higher than the processor's minimum
frequency of 400 MHz which is accessible with this modification.
In addition to the lower clock rate, I have seen a concomitant
reduction in both idle temps and at-the-wall power consumption.
Summary:
* Idle CPU freqs dropped from 1,384 MHz to 400 Mhz.
* Idle power consumption dropped from 7 W avg to 5 W.
* Idle temps have dropped from 50C on avg to 43C.
There are other well known reasons to switch to a tickless
timer including: reduced interrupt overhead, better use of CPU
resources, and reduced latency to name a few.

to extract the firmware type (remove the ".bin" in case there is no $3)

* Installing all the available firmwares as a whole, can support all the

* If we want to minimize the storage, we can customize to install the

The re-branded device comes with OpenWrt preinstalled, and an OpenWrt-based
U-Boot bootloader version. While the flash layout has been kept compatible
with the OpenWrt version found on the stock device (see [5]), the image format
changed, making a bootloader upgrade necessary.
Specifications:
SoC: Mediatek MT7981BA
RAM: 256MB
Flash: SPI-NOR 32 MiB (Winbond W25Q256)
WLAN: MT7976CN DBDC AX Wi-Fi
Switch: MT7531AE (4x LAN Gigabit ports, 1x WAN Gigabit port)
5G: Quectel RM520N modem
Watchdog: an external WDT connected to GPIO 6 is present and always running;
the built-in Mediatek watchdog is also present and effective, but
not used at the moment.
This porting has been tested only with 1x 5G modems installed (the device
supports up to two).
Installation:
Installation is possible via sysupgrade both in the stock device and
re-branded version. However, in the former case, updating the bootloader is
required.
OpenWrt-based U-Boot Bootloader installation
--------------------------------------------
The firmware flashed in the re-branded device at manifacturing time will
flash an OpenWrt-based U-Boot bootloader with some extra recovery features
(see [1]) at first boot.
To update the bootloader, you need to install the mtd-rw module and
insmod it:
And reboot, making sure all previous commands ran succesfully.
If something goes wrong, you can recover your device via the mtk_uartboot
tool.
In my testing, it was possible to start the process even without (un)-plugging
the device, may be handy for remote recovery.
Installation from stock device and firmware
-------------------------------------------
To install vanilla OpenWrt in the stock device (R5000 5G Industrial router
from Yinghua Technologies) running the stock vendor firmware, you will need
to update your bootloader as described in previous section. Remember to use
-F (force upgrade) and -n (not keeping settings).
U-Boot Recovery
---------------
This procedure has been tested only with the OpenWrt-based U-boot bootloader.
Assign your system static IP address 192.168.1.1 and start a TFTP server. The
device will look for an initramfs image named
openwrt-mediatek-filogic-gatonetworks_gdsp-initramfs-kernel.bin
(so you may use openwrt/bin/targets/mediatek/filogic as root dir for your
TFTP server).
Power on the device while keeping the reset button pressed, until you see
a TFTP request from 192.168.1.10. Your environment will be restored to it's
default state.
MAC addresses assignment
------------------------
MAC addresses are assigned slightly differently than in stock firmware. In
particular, the 5 GHz Wi-Fi uses 2.4 GHZ MAC + 1, rather than reusing it with
LA bit set as done in stock firmware. This MAC address is allocated to the
device, so it can be used.
The 2.4 GHz Wi-Fi MAC address is the label MAC. LAN MAC is used to set the
special U-Boot environment ethaddr variable.
device MAC address U-Boot env variable factory partition offset
2.4 GHz Wi-Fi :84 wifi_mac 0x4
5.8 GHz Wi-Fi :85 not present not present
WAN :86 wan_mac 0x24
LAN :87 lan_mac 0x2A
Notes
-----
[1]: the OpenWrt-based U-Boot bootloader you will find installed in the
re-branded device is configured to request for the initramfs image via
TFTP for $gdsp_tftp_tries times before trying normal boot from NOR flash.
Setting this U-Boot environment variable to 0x0 will disable the feature,
which is not implemented in this patch.
[2]: the exposed UART port is connected to ttyS1; the ttyS0 console port is
not exposed.
[3]: the provided bootloader environment has no provision for operating on
BL2 and the FIP partitions. This is an intentional choice to make it
(slightly) more difficult to brick the device.
[4]: it seems GPIO 6 is used both for the "SYS" LED and external WDT.
[5] BL2 expects to find FIP payload at a fixed offset, so some constraints
apply.

uboot-mediatek: add support for GatoNetworks GDSP
The GatoNetworks GDSP is a re-branded version of the R5000 5G Industrial
router from Yinghua Technologies.
Advantages over stock bootloader:
1. supports serving the external GPIO WDT, allowing for easier work in U-Boot
shell
2. supports cool features like netconsole, easy recovery, scripting and so on
3. allows using FIT image and image integrity validation
and ultimately gives you much more flexibility to implement your tweaks.
Known issues
------------
To make it easier to operate the device, console I/O multiplexing support has
been enabled in U-Boot configuration. Setting I/O related U-Boot environment
variables to something like "serial,nc" will have the desired effect. Still,
setting these variables to such a value in the persistent environment will
lead to a crash and make it impossible to boot the system or recover it. I
decided to leave it on anyway since I think it can be very practical in
development.
