-- gerrit commit 4454922cef2254744c71c36a1f1e9e9a2150beae Author: Antonio Borneo <[email protected]> Date: Fri Jun 15 16:30:41 2018 +0200 target/arm_adi_v5: sync CSW and TAR cache on apreg write When using apreg to change AP registers CSW or TAR we get internal cached value not valid anymore. Reuse the setup functions for CSW and TAR to write them. Invalidate the cached value before the call to force the write, thus keeping original apreg behaviour.
