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

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