The default value for CONFIG_RCU_CPU_STALL_TIMEOUT was changed from 60
seconds to 21 seconds in 2012 in the upstream kernel. Some targets
already use 21 seconds.
This patch changes the default value in the generic configuration to 21
seconds and removes the target specific configuration options.

Based on the existing documentation [1][2], I dare anyone to demonstrate that
we need to fine-tune these RCU parameters. The (performance) breakage potential
for doing so is immense, so let's just please put down this loaded footgun.
Disable CONFIG_RCU_EXPERT and its dependent symbols. Additionally, remove the
CONFIG_RCU_EXPERT symbol from the target kconfigs which contain it.

Combine fixed sizes of "kernel" and "rootfs" partitions into one
partition managed by OpenWrt splitter, it will allow better management
of chip capacity and less maintenance burden when compiled kernel image
will outgrow allocated size for kernel partition. This also changes kernel
image format, since splitter only manages kernel and rootfs partitions,
the dtb needs to be updated with the kernel, so for convenience, kernel is
packed to FIT image.

All patches of LSDK 19.03 were ported to Openwrt kernel.
We still used an all-in-one patch for each IP/feature for
OpenWrt.
Below are the changes this patch introduced.
- Updated original IP/feature patches to LSDK 19.03.
- Added new IP/feature patches for eTSEC/PTP/TMU.
- Squashed scattered patches into IP/feature patches.
- Updated config-4.14 correspondingly.
- Refreshed all patches.

This removes support for executing old 32 bit applications on 64 bit ARM
and MIPS kernels.
On OpenWrt we normally compile all the user space applications on our
own and do not support third party binary only modules especial not 32
bit applications on 64 bit CPUs.
This reduces the attack surface on such systems and should also save
some memory.

This patch is to upgrade kernel to 4.14 for layerscape.
patches-4.14 for layerscape included two categories.
- NXP Layerscape SDK kernel-4.14 patches
All patches on tag LSDK-18.09-V4.14 were ported to OpenWrt
kernel. Since there were hundreds patches, we had to make
an all-in-one patch for each IP/feature.
See below links for LSDK kernel.
https://lsdk.github.io/components.htmlhttps://source.codeaurora.org/external/qoriq/qoriq-components/linux
- Non-LSDK kernel patches
Other patches which were not in LSDK were just put in patches-4.14.
Kept below patches from patches-4.9.
303-dts-layerscape-add-traverse-ls1043.patch
821-add-esdhc-vsel-to-ls1043.patch

Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this

Add a new config option to allow to select the default compile
optimization level for the kernel.
Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.
Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.
Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.
Exceptions to the above are:
- lantiq, where the optimization for size is only required for the
xway_legacy subtarget but was set for the whole target
- mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
plenty of space and an optimization for size doesn't make much sense
- rb532, which has 128MByte flash
