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 <abrodkin@synopsys.com> Cc: Felix Fietkau <nbd@openwrt.org> Cc: Jo-Philipp Wich <jow@openwrt.org> Cc: Jonas Gorski <jogo@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@48240 3c298f89-4303-0410-b956-a3cf2f4a3e73

-Subject: [PATCH] openwrt: arc - remove dependency on DEVTMPFS
-
-OpenWRT builds initramfs so that it doesn't require DEVTMPFS so dropping
-this dependency. That helps to escape 2 separate kernel rebuilds with
-and without initramfs.
-
-2 builds happen because OpenWRT first builds kernel and later modules.
-When building entire kernel with simple "make" INITRAMFS sets to a real
-value and so was triggering DEVTMPFS selection. Then when building only
-modules with "make modules" command INITRAMFS is zeroed and so kernel
-config was changing that lead to full kernel rebuild.

-Subject: [PATCH] openwrt: arc - add OWRTDTB section
-
-This change allows OpenWRT to patch resulting kernel binary with
-external .dtb.
-
-That allows us to re-use exactky the same vmlinux on different boards
-given its ARC core configurations match (at least cache line sizes etc).
-
-""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
-.dtb right after it, keeping the string in place.
