//
// INTVEC -- Exception vector table.
// SWITAB -- Software interrupt vector table.
// ICODE -- Startup (cstartup) and exception code.
// DIFUNCT -- Dynamic initialization vectors used by C++.
// CODE -- Compiler generated code.

// CODE_ID -- Initializer for CODE_I (ROM).

// Data segments - may be placed anywhere in memory.

//
// CSTACK -- The stack used by C/C++ programs (system and user mode).
// IRQ_STACK -- The stack used by IRQ service routines.
// SVC_STACK -- The stack used in supervisor mode
// (Define other exception stacks as needed for
// FIQ, ABT, UND).
// HEAP -- The heap used by malloc and free in C and new and
// delete in C++.
// INITTAB -- Table containing addresses and sizes of segments that
// need to be initialized at startup (by cstartup).
// CHECKSUM -- The linker places checksum byte(s) in this segment,
// when the -J linker command line option is used.
// DATA_y -- Data objects.
//
// Where _y can be one of:
//
// _AN -- Holds uninitialized located objects, i.e. objects with
// an absolute location given by the @ operator or the
// #pragma location directive. Since these segments
// contain objects which already have a fixed address,
// they should not be mentioned in this linker command
// file.
// _C -- Constants (ROM).
// _I -- Initialized data (RAM).
// _ID -- The original content of _I (copied to _I by cstartup) (ROM).
// _N -- Uninitialized data (RAM).
// _Z -- Zero initialized data (RAM).
//
// Note: Be sure to use end values for the defined address ranges.
// Otherwise, the linker may allocate space outside the
// intended memory range.
