The option was introduced in upstream linux commit a6484045 ("[TCP]: Do
not present confusing congestion control options by default.").
The option is set to y in generic config and to the moment does not
incur additional size increment. Make it y for all so that packages
such as kmod-tcp-bbr do not have to set it on every occasion

At this moment layerscape images are ext4 only. It causes problem with
save changes durring sysupgrade and make "firstboot" and failsafe mode
useless.
This patch changes sd-card images to squashfs + f2fs combined images.
To make place, for saving config, kernel space ar now ext4 partition
with fit kernel.
This method of image generation is similar to rest of OpenWrt sd-card
targets.

Extended attributes are required for overlayfs and have hence been long
ago enabled for jffs2, but should be enabled unconditionally for all
other filesystems which may potentially serve as overlayfs' upper

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.html
https://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
822-rgmii-fixed-link.patch
Renamed and rebase them as below in patches-4.14,
303-add-DTS-for-Traverse-LS1043-Boards.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
option unless there really is a strong reason for it.

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

Some targets need 4K sectors for small flash chips (e.g. some
routerboards, where the entire chip is just one "erase block"), whereas
on other devices 4K sectors lead to horrible flash erase/write
performance.
Set the default limit in the generic kernel configuration to 4 MiB to
ensure that all new platforms don't use 4K sectors for bigger flash
chips. On all existing targets use 16 MiB for now to avoid regressions.
They will be changed individually in follow-up commits.
