From be6ae382dc153da51cf066c8dd523aa955f02531 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Mon, 9 Jun 2014 22:18:24 +0400 Subject: xtensa: fix sysmem reservation at the end of existing block When sysmem reservation occurs exactly at the end of an existing block that block is deleted, because it is incorrectly included in the range of memblocks to remove. Fix that by skipping such block.
