ixp4xx: Resurrect IXP4xx support using device tree
This resurrects the support for IXP4xx using device tree
rather than the old (deleted) board files. The final pieces
of IXP4xx board files were deleted in Linux v5.19.

Ext4 root filesystems on CF and USB are supported by the
default config.

We support these three initial targets:

- The Gateworks Avila GW2348 reference design has 64MB of RAM
  and 32MB of flash and also supports USB and CompactFlash.

- The Gateworks Cambria GW2358 reference design has 128MB of
  RAM and 32MB of flash and also supports USB and CompactFlash.

- The old and stable Linksys NSLU2 works fine as well, albeit
  it only has 32MB of RAM so it has been marked as non-default.
  The 8MB of flash can only fit the kernel, so it has been
  patched to boot from exteral media on USB. I have used
  it successfully as a NAS with ksmbd and LUCI web API, see:

fd0aaf93d1 realtek: add support for TP-Link T1600G-28TS v3
This is an RTL8382-based switch with 24 copper ports + 4 SFP ports

Specifications:
---------------
 * SoC:       Realtek RTL8382M
 * Flash:     32 MiB SPI flash
 * RAM:       256 MiB
 * Ethernet:  24x 10/100/1000 Mbps
 * Buttons:   1x "Reset" button
 * UART:      1x serial header, unpopulated
 * SFP:       4 SFP ports

Works:
------
  - (24) RJ-45 ethernet ports
  - Switch functions
  - Buttons
  - Sys LED on front panel (no port LEDs)

Not yet enabled:
----------------
  - Port LEDs (no driver for RTL8231 in this mode)
  - SFP cages (no driver for PHY)

Install via web interface:
-------------------------

Not supported at this time.

Install via serial console/tftp:
--------------------------------

The U-Boot firmware drops to a TP-Link specific "BOOTUTIL" shell at
38400 baud. There is no known way to exit out of this shell, and no
way to do anything useful.

Ideally, one would trick the bootloader into flashing the sysupgrade
image first. However, if the image exceeds 6MiB in size, it will not
work. To install OpenWRT:

Prepare a tftp server with:
 1. server address: 192.168.0.146
 2. the image as: "uImage.img"

Power on device, and stop boot by pressing any key.
Once the shell is active:
 1. Ground out the CLK (pin 16) of the ROM (U6)
 2. Select option "3. Start"
 3. Bootloader notes that "The kernel has been damaged!"
 4. Release CLK as soon as bootloader thinks image is corrupted.
 5. Bootloader enters automatic recovery -- details printed on console
 6. Watch as the bootloader flashes and boots OpenWRT.

Blind install via tftp:
-----------------------

This method works when it's not feasible to install a serial header.

Prepare a tftp server with:
 1. server address: 192.168.0.146
 2. the image as: "uImage.img"
 3. Watch network traffic (tcpdump or wireshark works)
 4. Power on the device.
 5. Wait 1-2 seconds then ground out the CLK (pin 16) of the ROM (U6)
 6. When 192.168.0.30 makes tftp requests, release pin 16
 7. Wait 2-3 minutes for device to auto-flash and boot OpenWRT

2657e8cab7 ipq40xx: wpj428: switch to zimage to fit kernel partition
Like with some other ipq40xx devices, the kernel image size for the WPJ428
is limited in stock u-boot. For that reason, the current release doesn't
include an image for the board.
By switching to the zImage format, the kernel image size is reduced which
re-enables the build process. The image boots and behaved normally through
a few days of testing.

Before the switch to kernel version 6.1, it was possible to reduce the
image size by enough when disabling UBIFS and its otherwise unneeded
dependencies.

rules.mk: make toolchain dirs define more consistent
Make toolchain dirs define more consistent between internal and external
toolchains.

Make use of specific dirs also for intenral toolchain and generilize
include and lib inclusion.

Also set TOOLCHAIN_ROOT_DIR for internal toolchain as this is what
packages should use to reference staging toolchain directory.

scripts/ext-toolchain: implement external GCC version detection
Some package may needs to enable compatibility option based on the GCC
version.

Currently the GCC version is set based on the default value and doesn't
actually reflect the real value provided by the external toolchain if
used.

Fix this by correctly detecting the GCC version in the external
toolchain and set the correct value in CONFIG_GCC_VERSION.

A new option is added in menuconfig to manually set the GCC version if
needed.

treewide: disable QUILT refresh for unsupported packages
Some packages won't ever have something to patch as they normally
install files or are meta-packages.

For these special packages, disable QUILT refresh.

dnsmasq: add support for RA option 31
The option 31 in the RA specifies the DNS search list, the support
to configure this via UCI is missing in case dnsmasq-dhcpv6 is used.

This commit uses the uci option domain (same as is done by odhcpd) to
read and pass the DNS search list to dnsmasq, which is then used by RA.

Hence, with this commit, we are able to configure DNS search list for the
RA messages via the uci config when dnsmsaq-dhcpv6 is used.

b8e52852bd ipq40xx: switch to performance governor by default
Doing a simple ping to my device shows this:

64 bytes from 10.0.253.101: icmp_seq=1 ttl=64 time=2.00 ms
64 bytes from 10.0.253.101: icmp_seq=2 ttl=64 time=2.02 ms
64 bytes from 10.0.253.101: icmp_seq=3 ttl=64 time=1.68 ms
64 bytes from 10.0.253.101: icmp_seq=4 ttl=64 time=1.91 ms
64 bytes from 10.0.253.101: icmp_seq=5 ttl=64 time=1.92 ms
64 bytes from 10.0.253.101: icmp_seq=6 ttl=64 time=2.04 ms

Some users even report higher values on older kernels:

64 bytes from 192.168.1.10: seq=0 ttl=64 time=0.612 ms
64 bytes from 192.168.1.10: seq=1 ttl=64 time=2.852 ms
64 bytes from 192.168.1.10: seq=2 ttl=64 time=2.719 ms
64 bytes from 192.168.1.10: seq=3 ttl=64 time=2.741 ms
64 bytes from 192.168.1.10: seq=4 ttl=64 time=2.808 ms

The problem is that the governor is set to Ondemand, which causes
the CPU to clock all the way down to 48MHz in some cases.

Switching to performance governor:

64 bytes from 10.0.253.101: icmp_seq=1 ttl=64 time=0.528 ms
64 bytes from 10.0.253.101: icmp_seq=2 ttl=64 time=0.561 ms
64 bytes from 10.0.253.101: icmp_seq=3 ttl=64 time=0.633 ms
64 bytes from 10.0.253.101: icmp_seq=4 ttl=64 time=0.526 ms

In theory, using the Performance governor should increase power draw,
but it looks like it really does not matter for this soc.

Using a calibrated precision DC power supply (cpu idle):

Ondemand
24.00V * 0.134A = 3.216 Watts
48.00V * 0.096A = 4.608 Watts

Performance
24.00V * 0.135A = 3.240 Watts
48.00V * 0.096A = 4.608 Watts

Let's simply switch to the Performance governor by default
to fix the general jittery behaviour on devices using this soc.

Tested on: MikroTik wAP ac
