/*
** LDF for ADSP-BF537.
** 
** 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.
** __WORKAROUNDS_ENABLED
**    Defined by compiler when -workaround is used to direct LDF to
**    link with libraries that have been built with work-arounds
**    enabled.
** USE_FILEIO
**    Always defined; enables the File I/O Support, which is necessary
**    for printf() to produce any output.
** USE_CACHE
** 	Makes use of Some L1 memory as cache. Implies the presence
** 	of at least some external memory.
** USE_SDRAM
**     Makes SDRAM available as standard program/data memory, with no
**     cache configuration of L1. Heap space is moved into SDRAM.
** USER_CRT
**   Specifies a custom or System Builder generated CRT object to use.
**   Makes use of Some L1 memory as cache. Implies the presence
**   of at least some external memory.
** _ADI_LIBIO
**   Use the ADI io library (default and fast)
** _DINKUM_IO
**   Use dinkum io library (slower but more compatible). Enabled
**   by the flag -cstd-io
**
** Memory map.
** 
** The known memory spaces are as follows:
** 
** 0xFFE00000 - 0xFFFFFFFF  Core MMR registers (2MB)
** 0xFFC00000 - 0xFFDFFFFF  System MMR registers (2MB)
** 0xFFB01000 - 0xFFBFFFFF  Reserved
** 0xFFB00000 - 0xFFB00FFF  Scratch SRAM (4K)
** 0xFFA14000 - 0xFFAFFFFF  Reserved
** 0xFFA10000 - 0XFFA13FFF  Code SRAM/CACHE (16K)
** 0xFFA0C000 - 0xFFA0FFFF  Reserved
** 0xFFA08000 - 0xFFA0BFFF  Instruction Bank B SRAM (16K)
** 0xFFA00000 - 0xFFA07FFF  Instruction Bank A SRAM (32K)
** 0xFF908000 - 0xFF9FFFFF  Reserved
** 0xFF904000 - 0xFF907FFF  Data Bank B SRAM/CACHE (16k)
** 0xFF900000 - 0XFF903FFF  Data Bank B SRAM (16k)
** 0xFF808000 - 0xFF8FFFFF  Reserved
** 0xFF804000 - 0xFF807FFF  Data Bank A SRAM/CACHE (16k)
** 0xFF800000 - 0XFF803FFF  Data Bank A SRAM (16k)
** 0xEF000800 - 0xFF800000  Reserved
** 0xEF000000 - 0xFF8007FF  Boot ROM (2K)
** 0x20400000 - 0xEEFFFFFF  Reserved
** 0x20300000 - 0x203FFFFF  ASYNC MEMORY BANK 3 (1MB)
** 0x20200000 - 0x202FFFFF  ASYNC MEMORY BANK 2 (1MB)
** 0x20100000 - 0x201FFFFF  ASYNC MEMORY BANK 1 (1MB)
** 0x20000000 - 0x200FFFFF  ASYNC MEMORY BANK 0 (1MB)
** 0x00000000 - 0x1FFFFFFF  SDRAM MEMORY (16MB - 512MB)
