/*
    Trace support.

    This tracer is using a buffer to trace the flow of the FW and dump misc values (see below for details).
    Currently, support is only for SKC.
    To enable support for other platforms:
     - Allocate a buffer for tracing in DMEM. The longer the better.
     - Use the DBG_init routine in sp.hive.c to initiatilize the tracer with the address and size selected.
     - Add trace points in the SP code wherever needed.
     - Enable the dump below with the required address and required adjustments.
	   Dump is called at the end of ia_css_debug_dump_sp_state().

/*
 dump_trace() : dump the trace points from DMEM2.
 for every trace point, the following are printed: index, major:minor and the 16-bit attached value.
 The routine looks for the first 0, and then prints from it cyclically.
 Data forma in DMEM2:
  first 4 DWORDS: header
   DWORD 0: data description
    byte 0: version
    byte 1: number of threads (for future use)
    byte 2+3: number ot TPs
   DWORD 1: command byte + data (for future use)
    byte 0: command
    byte 1-3: command signature
   DWORD 2-3: additional data (for future use)
  Following data is 4-byte oriented:
    byte 0:   major
	byte 1:   minor
	byte 2-3: data
