1/* Linker Script Original v1.3 by Jeff Frohwein */
2/* v1.0 - Original release */
3/* v1.1 - Added proper .data section support */
4/* v1.2 - Added support for c++ & iwram overlays */
5/* - Major contributions by Jason Wilkins. */
6/* v1.3 - .ewram section now can be used when */
7/* compiling for MULTIBOOT mode. This fixes */
8/* malloc() in DevKitAdvance which depends */
9/* on __eheap_start instead of end to define*/
10/* the starting location of heap space. */
11/* External global variable __gba_iwram_heap*/
12/* support added to allow labels end, _end, */
13/* & __end__ to point to end of iwram or */
14/* the end of ewram. */
15/* Additions by WinterMute */
16/* v1.4 - .sbss section added for unitialised */
17/* data in ewram */
18/* v1.5 - padding section added to stop EZF */
19/* stripping important data */
20/* v1.6 - added memory sections */
21
22/* This file is released into the public domain */
23/* for commercial or non-commercial use with no */
24/* restrictions placed upon it. */
25
26/* NOTE!!!: This linker script defines the RAM & */
27/* ROM start addresses. In order for it to work */
28/* properly, remove -Ttext and -Tbss linker */
29/* options from your makefile if they are */
30/* present. */
31
32/* You can use the following to view section */
33/* addresses in your .elf file: */
34/* objdump -h file.elf */
35/* Please note that empty sections may incorrectly*/
36/* list the lma address as the vma address for */
37/* some versions of objdump. */
