From 3d0620b607ff6459fec9d30efc1e0589bbd010f9 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 8 Apr 2020 16:54:34 +0200 Subject: score: Optimize Workspace Handler initialization The BSPs provide memory for the workspace initialization via _Memory_Get(). Most BSPs provide exactly one memory area. Only two BSPs provide more than one memory area (arm/altera-cyclone-v and bsps/powerpc/mpc55xxevb). Only if more than one memory area is provided, there is a need to use _Heap_Extend(). Provide two implementations to initialize the workspace handler and let the BSP select one of the implementations based on the number of provided memory areas. This gets rid of a dependency on _Heap_Extend(). It also avoids dead code sections for most BSPs. --- bsps/shared/start/wkspaceinitone.c | 46 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 bsps/shared/start/wkspaceinitone.c (limited to 'bsps/shared/start/wkspaceinitone.c') diff --git a/bsps/shared/start/wkspaceinitone.c b/bsps/shared/start/wkspaceinitone.c new file mode 100644 index 0000000000..91d007d100 --- /dev/null +++ b/bsps/shared/start/wkspaceinitone.c @@ -0,0 +1,46 @@ +/* SPDX-License-Identifier: BSD-2-Clause */ + +/** + * @file + * + * @ingroup RTEMSScoreWorkspace + * + * @brief This source file contains the _Workspace_Handler_initialization() + * implementation which supports exactly one memory area. + */ + +/* + * Copyright (C) 2020 embedded brains GmbH (http://www.embedded-brains.de) + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
