+Subject: [PATCH 1/2] aarch64: introduce build support for aarch64_be target
+
+Upstream-Status: backport
+
+Introduce support for aarch64_be, aarch64 big endian, target.
+We would like to reuse all code that was done for aarch64
+(little endian) target. So we do similar thing that is done
+for ARM v7 (arm) target for any aarch64* arch we set it
+just to aarch64.

+Subject: [PATCH 2/2] aarch64: fix wrong big_endian flag in aarch64_be case
+
+Upstream-Status: backport
+
+Set local_addr_space.big_endian flag according to current target
+endianness. Before it was set by memset to 0, which corresponds
+to little endian and it worked perfectly fine for aarch64.
+But it breaks aarch64_be because dwarf_readu16, dwarf_readu32,
+etc functions do not read values correctly since they operate
+with wrong idea about current target endianness.
