Kernel commit b6ae6fee73eab568ba49a4a489fdac6bb5027997 removed the
RTO-based flush logic in stm32-usart.
As a result, the RT patch no longer applies cleanly because it
modifies the receive_chars() call using the old context.
Update the RT patch to match the new baseline while preserving
the PREEMPT_RT locking changes.

The fragment-07-rt-sysvinit.config disables several cgroup
controllers (PIDS, CPUACCT, DEVICE, FREEZER, etc.) and is
intended for minimal RT configurations using sysvinit.
It is currently applied unconditionally for STM32MP RT builds,
including systemd-based systems. This breaks container runtimes
such as podman, which require full cgroup support (notably
CONFIG_CGROUP_PIDS) when running on PREEMPT_RT kernels.
Apply the sysvinit RT fragment only when the 'sysvinit'
DISTRO_FEATURE is enabled, leaving systemd configurations
unaffected.

CONFIG_BRIDGE_NETFILTER depends on CONFIG_NETFILTER_ADVANCED.

While BTRFS can be useful on server-class systems (e.g. RAID-based or
snapshot-heavy setups), enabling it unconditionally is not appropriate
for typical embedded systems. It introduces unnecessary kernel
complexity, pulls in RAID6 support, and increases kernel boot time by
approximately 0.7 seconds.
This reverts commit 503e50f392.

Add a variable analogous to TRUSTFENCE_SIGN to enable/disable artifact
encryption. Deprecate TRUSTFENCE_DEK_PATH in favor of TRUSTFENCE_KEYS_PATH to
use a more generic name and avoid overloading it as an on/off flag. Add per-key
variables for encryption key filenames to avoid hardcoded names and allow
platform overrides.

This patch fixes build failures of the virtio_trans driver (Cortex-A9, 32-bit ARM)
when building a PREEMPT_RT-enabled kernel. The errors were caused by
unresolved 64-bit division symbols (__aeabi_uldivmod / __aeabi_ldivmod)
generated when the driver was compiled as a module.
Changes included:
* virtio_trans.c:
- Replace 64-bit modulus operations (`idx % vt->{tx,rx}_vring_size`) with
kernel-safe 64-bit division macros using `div_u64_rem()`.
This prevents implicit calls to non-exported ARM EABI helpers that are not
available to kernel modules on 32-bit ARM.
* fragment-nxp-rt.config:
- Enable the mailbox framework (`CONFIG_MAILBOX=y`) required by virtio
mailbox-based transports.
- Build the virtio transport driver into the kernel (`CONFIG_VIRTIO_TRANS=y`)
instead of as a module, ensuring proper symbol resolution
during link time. Without this a license error is shown when building
the kernel in yocto.

Yocto added kernel local version support by using the KERNEL_LOCALVERSION
variable. It conflicts with the "fsl-kernel-localversion" class from
the meta-freescale layer, resulting in a duplicated local version in the
kernel release label (uname -r). Use the current Yocto support to avoid
that duplication instead of meta-freescale's class.
This enables further simplification of the 'copy_defconfig' task for NXP
and STM platforms using common code.

Assembling a FIT image requires that all artifacts are ready before calling
assemble_fitimage(), which occurs before do_install() and after do_compile().
To ensure the Linux kernel recipe provides the final artifacts in the correct
location, this commit replaces the additional do_install() step with an
additional do_compile() step, ensuring that all necessary artifacts are
available before assemble_fitimage().
