/*
** LDF for ADSP-BF533.
** 
** This LDF defines an example layout for a system which uses only
** the available L1 SRAM. It does not assume the presence of any
** external memory. See below for memory map descriptions.
** 
** There are a number of configuration options that can be specified
** either by compiler flags, or by linker flags directly. The options are:
** 
** USE_PROFILER0
** 	Enabled by -p. Link in profiling library, and write results to
** 	both stdout and mon.out.
** USE_PROFILER1
** 	Enabled by -p1. Only write profiling data to mon.out.
** USE_PROFILER2
** 	Enabled by -p2. Only write profiling data to stdout.
** USE_PROFILER
** 	Equivalent to USE_PROFILER0.
** USE_FILEIO
**	Always defined; enables the File I/O Support, which is necessary
**	for printf() to produce any output.
** CRT
** 	Link in C++ runtime.
** USERMODE
**	Set up event handlers and go to usermode.
** CSYNC_DEFINED
**	Link with libraries that have been built with -csync.
** 
** Memory map.
** 
** The known memory spaces are as follows:
** 
** Internal Memory:
** 0xFFE0 0000 - 0xFFFF FFFF		Core MMR registers (2MB)
** 0xFFC0 0000 - 0xFFDF FFFF		System MMR registers (2MB)
** 0xFFB0 1000 - 0xFFBF FFFF		Reserved
** 0xFFB0 0000 - 0xFFB0 0FFF		Scratch SRAM (4K)
** 0xFFA1 4000 - 0xFFAF FFFF		Reserved
** 0xFFA0 0000 - 0xFFA1 3FFF		Instruction SRAM (82K)
** 0xFF90 8000 - 0xFF9F FFFF		Reserved
** 0xFF90 0000 - 0xFF90 7FFF		Data Bank B SRAM (32K)
** 0xFF80 8000 - 0xFF8F FFFF		Reserved
** 0xFF80 0000 - 0xFF80 7FFF		Data Bank A SRAM (32K)
** 0xEF00 0000 - 0xFF7F FFFF		Reserved
**
** External Memory:
** 0x2040 0000 - 0xEEFF FFFF		Reserved
** 0x2030 0000 - 0x203F FFFF		Async Mem Bank 3 (1M)
** 0x2020 0000 - 0x202F FFFF		Async Mem Bank 2 (1M)
** 0x2010 0000 - 0x201F FFFF		Async Mem Bank 1 (1M)
** 0x2000 0000 - 0x200F FFFF		Async Mem Bank 0 (1M)
** 0x0800 0000 - 0x1FFF FFFF		Reserved
** 0x0000 0000 - 0x07FF FFFF		SDRAM (16M - 128M)
