From e7ae8d174eec0b3b9de92b76abc15f3f53b98f1c Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Fri, 9 Oct 2020 14:14:46 +0200 Subject: MIPS: replace add_memory_region with memblock add_memory_region was the old interface for registering memory and was already changed to used memblock internaly. Replace it by directly calling memblock functions.
