Analog公司的ADSP_BF532上面实现以太网接口的源码

/*
** LDF for ADSP-BF535.
**
** 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
**      Link in support for file I/O (fopen, etc). Also necessary
**      for argc/argv handling.
** USE_CACHE
**      Makes use of Some L1 memory as cache. Implies the presence
**      of at least some external memory.
