-CodeSourcery on Linux
-^^^^^^^^^^^^^^^^^^^^^
-
-  If you select the CodeSourcery toolchain, the make system will assume that you
-  are running a Windows version of the toolchain.  If you are running under Linux,
-  the the make will probably fail.  The fix is to edit your Make.defs file and
-  use something like:
-
-    CROSSDEV = arm-none-eabi-
-    WINTOOL = n
-    MKDEP = $(TOPDIR)/tools/mkdeps.sh
-    ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
-    ARCHINCLUDES = -I. -isystem $(TOPDIR)/include
-    ARCHXXINCLUDES = -I. -isystem $(TOPDIR)/include -isystem $(TOPDIR)/include/cxx
-    ARCHSCRIPT = -T$(TOPDIR)/configs/$(CONFIG_ARCH_BOARD)/ostest/$(LDSCRIPT)
-    MAXOPTIMIZATION = -O2
-
-  Where LDSCRIPT is defined to be either ld.script or ld.script.dfu.  The values
-  for TOPDIR is provided by the make system; the value for CONFIG_ARCH_BOARD is
-  provided in your defconfig file. 'ostest' refers to the ostest/ configuration;
-  this would be different for other configurations.
