From 7bbf4117c6fe4b764d9d7c62fb2bcf6dd93bff2c Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Tue, 3 Oct 2017 18:02:59 +0200 Subject: ar71xx: Add kernel 4.9 support This add support for kernel 4.9 to the ar71xx target. It was compile tested with the generic, NAND and mikrotik subtarget. Multiple members of the community tested it on their boards and did not report any major problem so far. Especially the NAND part received some changes to adapt to the new kernel APIs. The serial driver hack used for the Arduino Yun was not ported because the kernel changed there a lot.
