9;* Linker file for the ARMCC.
10;*
11;* The main purpose of the linker script is to describe how the sections in the
12;* input files should be mapped into the output file, and to control the memory
13;* layout of the output file.
14;*
15;* \note The entry point location is fixed and starts at 0x10000000. The valid
16;* application image should be placed there.
17;*
18;* \note The linker files included with the PDL template projects must be
19;* generic and handle all common use cases. Your project may not use every
20;* section defined in the linker files. In that case you may see the warnings
21;* during the build process: L6314W (no section matches pattern) and/or L6329W
22;* (pattern only matches removed unused sections). In your project, you can
23;* suppress the warning by passing the "--diag_suppress=L6314W,L6329W" option to
24;* the linker, simply comment out or remove the relevant code in the linker
25;* file.
