From: Felix Fietkau Date: Fri, 15 Jan 2016 10:49:01 +0000 (+0000) Subject: arc770: bump linux kernel from 4.3 to 4.4 X-Git-Tag: reboot~885 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4514589182d1cdb1f2dd6859599c97747b5ca52a;p=openwrt%2Fstaging%2Fpepe2k.git arc770: bump linux kernel from 4.3 to 4.4 This switch involved: [1] Regeneration of config (few options went away) [2] Regeneration of patches so they apply cleanly (different offsets) [3] Update of .dts files because we now explicitly specify memory regions in use as opposed to previously used offset from 0x8000_0000 Signed-off-by: Alexey Brodkin Cc: Felix Fietkau Cc: Jo-Philipp Wich Cc: Jonas Gorski SVN-Revision: 48240 --- diff --git
