  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

  config CMD_BEDBUG
  	bool "bedbug"
  	help
  	  The bedbug (emBEDded deBUGger) command provides debugging features
  	  for some PowerPC processors. For details please see the
  	  docuemntation in doc/README.beddbug

  config CMD_DIAG
  	bool "diag - Board diagnostics"
  	help
  	  This command provides access to board diagnostic tests. These are
  	  called Power-on Self Tests (POST). The command allows listing of
  	  available tests and running either all the tests, or specific tests
  	  identified by name.

  config CMD_IRQ
  	bool "irq - Show information about interrupts"

  	depends on !ARM && !MIPS && !SH

  	help
  	  This enables two commands:
  
  	     interrupts - enable or disable interrupts
  	     irqinfo - print device-specific interrupt information

  
  config CMD_KGDB
  	bool "kgdb - Allow debugging of U-Boot with gdb"
  	help
  	  This enables a 'kgdb' command which allows gdb to connect to U-Boot
  	  over a serial link for debugging purposes. This allows
  	  single-stepping, inspecting variables, etc. This is supported only
  	  on PowerPC at present.

  config CMD_LOG
  	bool "log - Generation, control and access to logging"
  	help
  	  This provides access to logging features. It allows the output of
  	  log data to be controlled to a limited extent (setting up the default

  	  maximum log level for emitting of records). It also provides access
  	  to a command used for testing the log system.

  config CMD_TRACE
  	bool "trace - Support tracing of function calls and timing"
  	help
  	  Enables a command to control using of function tracing within
  	  U-Boot. This allows recording of call traces including timing
  	  information. The command can write data to memory for exporting
  	  for analsys (e.g. using bootchart). See doc/README.trace for full
  	  details.

  	help
  	  UBI is a software layer above MTD layer which admits use of LVM-like
  	  logical volumes on top of MTD devices, hides some complexities of
  	  flash chips like wear and bad blocks and provides some other useful
  	  capabilities. Please, consult the MTD web site for more details
  	  (www.linux-mtd.infradead.org). Activate this option if you want
  	  to use U-Boot UBI commands.

  config CMD_UBIFS
  	tristate "Enable UBIFS - Unsorted block images filesystem commands"

  	depends on CMD_UBI

  	select CRC32

  	select LZO

  	default y if CMD_UBI

  	help
  	  UBIFS is a file system for flash devices which works on top of UBI.
