	  Depending on the number of commands enabled, this can add
	  substantially to the size of U-Boot.

config HUSH_PARSER

	  This option enables the "hush" shell (from Busybox) as command line
	  interpreter, thus enabling powerful command line syntax like

	  by the firmware, typically U-Boot but possibly an earlier firmware
	  module, if U-Boot is chain-loaded from something else. ACPI tables
	  can also include code, to perform hardware-specific tasks required

	  checking the state of devices during boot when debugging device
	  drivers, etc.

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.
