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.

Since CONFIG_DYNAMIC_DEBUG is already managed via the KERNEL_DYNAMIC_DEBUG
setting in Config-kernel.in (default N), remove or disable it in target
configs which unconditionally enable it, along with the related setting
CONFIG_DYNAMIC_DEBUG_CORE. This saves several KB in the kernels for
ipq40xx, ipq806x, filogic, mt7622, qoriq, and sunxi.

This deactivates the CONFIG_COMPAT kernel option.
With CONFIG_COMPAT the kernel will provide syscall interfaces for arm32
binaries in addition to the interfaces needed for arm64 binaries.
In OpenWrt the complete userspace is compiled for this specific
architecture and support for 32 bit ARM applications is not needed.
This reduces the size and the attack surface for the systems.
On all other targets CONFIG_COMPAT is already deactivated.

This activates the CONFIG_ARM64_SW_TTBR0_PAN option for all arm64
kernels by default.
The CONFIG_ARM64_SW_TTBR0_PAN option prevents the kernel form accessing
user space memory directly. This makes it harder to exploit the kernel.
This is activated by default and was already activate on all other arm64
targets before.

This activates CONFIG_HARDENED_USERCOPY for the remaining targets. This
adds additional checks in the copy_from_user() and copy_to_user()

This was not activated for ARCHS38 before because of a bug in the Linux

We need to reset KERNEL_LOADADDR if we use it on a per-device base.
Otherwise the previous value will be kept in case a device doesn't
define KERNEL_LOADADDR and relies on the default.
Move initializing KERNEL_LOADADDR to target/linux/mediatek/image/Makefile,
similar to how it's done also on the ramips target.
This fixes image size related breakage on devices which rely on the
default value of KERNEL_LOADADDR.
While at it use 0x48000000 which is more common than the previous default
0x44000000 for the filogic subtarget.

The mxl-gpy driver apparently was built in the assumption that SGMII
auto-negotiation is always switched on at the MAC. This may be true for
few rather recent drivers (why?), but certainly isn't for most drivers
unless 'managed = "in-band-status"' is set in device tree. Add patch to
the mediatek target which reduces mxl-gpy to behave more like an
ordinary PHY driver using out-of-band status.
This allows to use these PHYs without rate-adaptation which seems to be
at least partially broken/racy in some revisions of the PHY and/or
internal PHY firmware.

reachable at 192.168.1.66/24. Rename the image to tufax4200.bin.
2. Connect the TFTP server to the AX4200. Conect to the serial console,
interrupt the autoboot process by pressing '4' when prompted.
3. Download & Boot the OpenWrt initramfs image.
$ setenv ipaddr 192.168.1.1
