/*
** LDF for ADSP-BF533.
** 
** 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.
** PARTITION_EZKIT_SDRAM
**    The ADSP-BF533 is supplied with one external bank populated with
**    with 32MB of SDRAM. The ADSP-BF533 EBIU allows for 4 internal banks
**    in an external SDRAM bank to be accessed simultaneously, reducing the
**    stall on access compared to keeping program and data in one bank.
**    Defining this macro partitions the SDRAM into 4 8MB banks with the
**    intention of use being: bank0 - heap, bank1 - data, bank2 - data/bsz,
**    bank3 - program. See 533 Hardware Reference Manual, 17-22, SDRAM
**    controler.
**    NOTE: Either USE_CACHE or USE_SDRAM must also be defined to use this.
** USER_CRT
**    Specifies a custom or System Builder generated CRT object to use.
** _ADI_LIBIO
**   Use the ADI io library (default and fast)
** _DINKUM_IO
**   Use dinkum io library (slower but more compatible). Enabled
**   by the flag -full-io
