analog device vdsp LAN driver and examples

/*
** Default LDF for a VDK project on the ADSP-BF537.
** 
** There are configuration options that can be specified either by compiler
** flags, or by linker flags directly. These options are:
**
** __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_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.
** USE_SCRATCHPAD_STACK
**   Use scratchpad for system stack. Note only 4k memory.
** USE_SCRATCHPAD_HEAP
**   Use scratchpad for dynamic heap allocation. Note only 4k memory.
** USE_SDRAM_STACK
**   Use SDRAM for system stack rather than L1 default. Should allow for
**   much larger stack but likely to have a significant performance impact.
** USE_SDRAM_HEAP
**   Use SDRAM for dynamic heap allocation rather than L1 default. Should
**   result in a much larger heap being available but can have a significant
**   performance impact.
** USER_CRT
**   Specifies a custom or System Builder generated CRT startup object to use.
** USER_CPLBTAB
**   Specifies a custom or System Builder generated CPLB configuration
**   definition.
** IEEEFP
**   Defined by the compiler when switch -ieee-fp is used to direct the
**   use of slower but more IEEE conformant floating-point emulation.
** _DINKUM_IO
**   Use dinkum io library (slower but more compatible). Enabled
**   by the flag -full-io
** __MEMINIT__
**   Macro defined by the linker when -meminit is used to enable runtime
**   initialization.
