Hauke Mehrtens 89f8a8be7f kernel: Deactivate CONFIG_COMPAT_BRK
CONFIG_COMPAT_BRK disables the heap randomization which is only needed
for very old and ancient user space applications, I am not aware that we
run any of these, just deactivate this option for these targets to allow
heap randomization.

Biwen Li 0a827ebd2f layerscape: upgrade kernel to 4.14
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
  712-sdk-dpaa-rgmii-fixed-link.patch
  824-mmc-sdhci-of-esdhc-add-voltage-switch-support-for-ls.patch

Felix Fietkau 212aa33226 kernel: enable memory compaction
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.

Hauke Mehrtens 3f7f27892e layerscape: armv7: activate USB support.
The feature flags say that this target supports USB so packages
depending on USB are being build, but actually the kernel configuration
misses USB support. It looks like this SoC supports USB, so activate it.
