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. More info about LSDK and the kernel: - https://lsdk.github.io/components.html - https://source.codeaurora.org/external/qoriq/qoriq-components/linux Signed-off-by: Biwen Li <biwen.li@nxp.com> Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>
