7 	  Enable U-Boot's command-line functions. This provides a means
8 	  to enter commands into U-Boot for a wide variety of purposes. It
9 	  also allows scripts (containing commands) to be executed.
10 	  Various commands and command categorys can be indivdually enabled.

533 config CMD_IOTRACE
534 	bool "iotrace - Support for tracing I/O activity"
535 	help
536 	  Provides an 'iotrace' command which supports recording I/O reads and
537 	  writes in a trace buffer in memory . It also maintains a checksum
538 	  of the trace records (even if space is exhausted) so that the
539 	  sequence of I/O accesses can be verified.
540 
541 	  When debugging drivers it is useful to see what I/O accesses were
542 	  done and in what order.
543 
544 	  Even if the individual accesses are of little interest it can be
545 	  useful to verify that the access pattern is consistent each time
546 	  an operation is performed. In this case a checksum can be used to
547 	  characterise the operation of a driver. The checksum can be compared
548 	  across different runs of the operation to verify that the driver is
549 	  working properly.
550 
551 	  In particular, when performing major refactoring of the driver, where
552 	  the access pattern should not change, the checksum provides assurance
553 	  that the refactoring work has not broken the driver.
554 
555 	  This works by sneaking into the io.h heder for an architecture and
556 	  redirecting I/O accesses through iotrace's tracing mechanism.
557 
558 	  For now no commands are provided to examine the trace buffer. The
559 	  format is fairly simple, so 'md' is a reasonable substitute.
560 
561 	  Note: The checksum feature is only useful for I/O regions where the
562 	  contents do not change outside of software control. Where this is not
563 	  suitable you can fall back to manually comparing the addresses. It
564 	  might be useful to enhance tracing to only checksum the accesses and
565 	  not the data read/written.
