From 635b45d60878887fba7425f61870cf2a9a6f3102 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Wed, 27 Aug 2014 12:16:16 -0700 Subject: libpayload arm64: Add library helpers Add library helpers to access standard arm64 registers. This library also provides functions to directly read/write register based on current el. So, rest of the code doesnt need to keep checking the el and call appropriate function based on that.
