//   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_I     -- Compiler generated code declared __ramfunc (executes in RAM)
//   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).
