From e53fa62c17a87c8a6cdbe5fb265c876bb87bcff2 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Fri, 22 Dec 2017 13:53:36 -0800 Subject: hw/xtensa: extract xtensa_create_memory_regions XTFPGA boards should populate core memory regions the same way sim machine does. Move xtensa_create_memory_regions implementation to a separate file and use it to create instruction and data memory regions on XTFPGA boards.
