+config CMDLINE
+	bool "Support U-Boot commands"
+	default y
+	help
+	  Enable U-Boot's command-line functions. This provides a means
+	  to enter commands into U-Boot for a wide variety of purposes. It
+	  also allows scripts (containing commands) to be executed.
+	  Various commands and command categorys can be indivdually enabled.
+	  Depending on the number of commands enabled, this can add
+	  substantially to the size of U-Boot.
+
+config HUSH_PARSER
+	bool "Use hush shell"
+	depends on CMDLINE
+	help
+	  This option enables the "hush" shell (from Busybox) as command line
+	  interpreter, thus enabling powerful command line syntax like
+	  if...then...else...fi conditionals or `&&' and '||'
+	  constructs ("shell scripts").
+
+	  If disabled, you get the old, much simpler behaviour with a somewhat
+	  smaller memory footprint.

+	  Operating System about devices in the system. The tables are set up
+	  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
+	  by the Operating Systems. This allows some amount of separation
+	  between the firmware and OS, and is particularly useful when you
+	  want to make hardware changes without the OS needing to be adjusted.

+
+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.

+ * I2C Functions similar to the standard memory functions.
+ *
+ * There are several parameters in many of the commands that bear further
+ * explanations:
+ *
+ * {i2c_chip} is the I2C chip address (the first byte sent on the bus).
+ *   Each I2C chip on the bus has a unique address.  On the I2C data bus,
+ *   the address is the upper seven bits and the LSB is the "read/write"
+ *   bit.  Note that the {i2c_chip} address specified on the command
+ *   line is not shifted up: e.g. a typical EEPROM memory chip may have
+ *   an I2C address of 0x50, but the data put on the bus will be 0xA0
+ *   for write and 0xA1 for read.  This "non shifted" address notation
+ *   matches at least half of the data sheets :-/.
+ *
+ * {addr} is the address (or offset) within the chip.  Small memory
+ *   chips have 8 bit addresses.  Large memory chips have 16 bit
+ *   addresses.  Other memory chips have 9, 10, or 11 bit addresses.
+ *   Many non-memory chips have multiple registers and {addr} is used
+ *   as the register index.  Some non-memory chips have only one register
+ *   and therefore don't need any {addr} parameter.
+ *
+ *   The default {addr} parameter is one byte (.1) which works well for
+ *   memories and registers with 8 bits of address space.
+ *
+ *   You can specify the length of the {addr} field with the optional .0,
+ *   .1, or .2 modifier (similar to the .b, .w, .l modifier).  If you are
+ *   manipulating a single register device which doesn't use an address
+ *   field, use "0.0" for the address and the ".0" length field will
+ *   suppress the address in the I2C data stream.  This also works for
+ *   successive reads using the I2C auto-incrementing memory pointer.
+ *
+ *   If you are manipulating a large memory with 2-byte addresses, use
+ *   the .2 address modifier, e.g. 210.2 addresses location 528 (decimal).
+ *
+ *   Then there are the unfortunate memory chips that spill the most
+ *   significant 1, 2, or 3 bits of address into the chip address byte.
+ *   This effectively makes one chip (logically) look like 2, 4, or
+ *   8 chips.  This is handled (awkwardly) by #defining
+ *   CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW and using the .1 modifier on the
+ *   {addr} field (since .1 is the default, it doesn't actually have to
+ *   be specified).  Examples: given a memory chip at I2C chip address
+ *   0x50, the following would happen...
+ *     i2c md 50 0 10   display 16 bytes starting at 0x000
+ *                      On the bus: <S> A0 00 <E> <S> A1 <rd> ... <rd>
+ *     i2c md 50 100 10 display 16 bytes starting at 0x100
+ *                      On the bus: <S> A2 00 <E> <S> A3 <rd> ... <rd>
+ *     i2c md 50 210 10 display 16 bytes starting at 0x210
+ *                      On the bus: <S> A4 10 <E> <S> A5 <rd> ... <rd>
+ *   This is awfully ugly.  It would be nice if someone would think up
+ *   a better way of handling this.

+ * Three environment variables are used by the parsing routines:
+ *
+ * 'partition' - keeps current partition identifier
+ *
+ * partition  := <part-id>
+ * <part-id>  := <dev-id>,part_num
+ *
+ *
+ * 'mtdids' - linux kernel mtd device id <-> u-boot device id mapping
+ *
+ * mtdids=<idmap>[,<idmap>,...]
+ *
+ * <idmap>    := <dev-id>=<mtd-id>
+ * <dev-id>   := 'nand'|'nor'|'onenand'<dev-num>
+ * <dev-num>  := mtd device number, 0...
+ * <mtd-id>   := unique device tag used by linux kernel to find mtd device (mtd->name)
+ *
+ *
+ * 'mtdparts' - partition list
+ *
+ * mtdparts=mtdparts=<mtd-def>[;<mtd-def>...]
+ *
+ * <mtd-def>  := <mtd-id>:<part-def>[,<part-def>...]
+ * <mtd-id>   := unique device tag used by linux kernel to find mtd device (mtd->name)
+ * <part-def> := <size>[@<offset>][<name>][<ro-flag>]
+ * <size>     := standard linux memsize OR '-' to denote all remaining space
+ * <offset>   := partition start offset within the device
+ * <name>     := '(' NAME ')'
+ * <ro-flag>  := when set to 'ro' makes partition read-only (not used, passed to kernel)
+ *
+ * Notes:

+ * - if the above variables are not set defaults for a given target are used

+	 *              address and checking for aliasing.
+	 *              This test will find single-bit

+
+	 * Notes:	For best results, the selected base
+	 *              address should have enough LSB 0's to
+	 *              guarantee single address bit changes.
+	 *              For example, to test a 64-Kbyte
+	 *              region, select a base address on a
+	 *              64-Kbyte boundary. Also, select the
