From 0d625f400bcab5361484a5446aa54133fd6fe213 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Sun, 12 Sep 2021 11:05:47 -0500 Subject: [PATCH] riscv: Fix setting no-map in reserved memory nodes The no-map property is wrongly skipped if a no-map reserved memory node follows one without that property. Fix this by not remembering the absence of a no-map property across loop iterations.
