  config CMD_IOTRACE
  	bool "iotrace - Support for tracing I/O activity"
  	help
  	  Provides an 'iotrace' command which supports recording I/O reads and
  	  writes in a trace buffer in memory . It also maintains a checksum
  	  of the trace records (even if space is exhausted) so that the
  	  sequence of I/O accesses can be verified.
  
  	  When debugging drivers it is useful to see what I/O accesses were
  	  done and in what order.
  
  	  Even if the individual accesses are of little interest it can be
  	  useful to verify that the access pattern is consistent each time
  	  an operation is performed. In this case a checksum can be used to
  	  characterise the operation of a driver. The checksum can be compared
  	  across different runs of the operation to verify that the driver is
  	  working properly.
  
  	  In particular, when performing major refactoring of the driver, where
  	  the access pattern should not change, the checksum provides assurance
  	  that the refactoring work has not broken the driver.
  
  	  This works by sneaking into the io.h heder for an architecture and
  	  redirecting I/O accesses through iotrace's tracing mechanism.
  
  	  For now no commands are provided to examine the trace buffer. The
  	  format is fairly simple, so 'md' is a reasonable substitute.
  
  	  Note: The checksum feature is only useful for I/O regions where the
  	  contents do not change outside of software control. Where this is not
  	  suitable you can fall back to manually comparing the addresses. It
  	  might be useful to enhance tracing to only checksum the accesses and
  	  not the data read/written.
