 	  Define this if you don't want to or can't have an environment stored
 	  on a storage medium. In this case the environment will still exist
 	  while U-Boot is running, but once U-Boot exits it will not be
 	  stored. U-Boot will therefore always start up with a default
 	  environment.

 config ENV_IS_IN_EEPROM
 	bool "Environment in EEPROM"

 	help
 	  Use this if you have an EEPROM or similar serial access
 	  device and a driver for it.

 	  - CONFIG_ENV_OFFSET:
 	  - CONFIG_ENV_SIZE:

 	  These two #defines specify the offset and size of the
 	  environment area within the total memory of your EEPROM.

 	  Note that we consider the length of the address field to
 	  still be one byte because the extra address bits are hidden
 	  in the chip address.

 	  - CONFIG_ENV_EEPROM_IS_ON_I2C
 	  define this, if you have I2C and SPI activated, and your
 	  EEPROM, which holds the environment, is on the I2C bus.

 	  - CONFIG_I2C_ENV_EEPROM_BUS
 	  if you have an Environment on an EEPROM reached over
 	  I2C muxes, you can define here, how to reach this
 	  EEPROM. For example:

 	  #define CONFIG_I2C_ENV_EEPROM_BUS	  1

 	  EEPROM which holds the environment, is reached over
 	  a pca9547 i2c mux with address 0x70, channel 3.

 	help
 	  Define this if you have a flash device which you want to use for the
 	  environment.

 	  a) The environment occupies one whole flash sector, which is
 	   "embedded" in the text segment with the U-Boot code. This
 	   happens usually with "bottom boot sector" or "top boot
 	   sector" type flash chips, which have several smaller
 	   sectors at the start or the end. For instance, such a
 	   layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
 	   such a case you would place the environment in one of the
 	   4 kB sectors - with U-Boot code before and after it. With
 	   "top boot sector" type flash chips, you would put the
 	   environment in one of the last sectors, leaving a gap
 	   between U-Boot and the environment.

 	  CONFIG_ENV_OFFSET:

 	   Offset of environment data (variable area) to the
 	   beginning of flash memory; for instance, with bottom boot
 	   type flash chips the second sector can be used: the offset
 	   for this sector is given here.

 	   CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE.

 	  CONFIG_ENV_ADDR:

 	   This is just another way to specify the start address of
 	   the flash sector containing the environment (instead of
 	   CONFIG_ENV_OFFSET).

 	  CONFIG_ENV_SECT_SIZE:

 	   Size of the sector containing the environment.


 	  b) Sometimes flash chips have few, equal sized, BIG sectors.
 	   In such a case you don't want to spend a whole sector for
 	   the environment.

 	  CONFIG_ENV_SIZE:

 	   If you use this in combination with CONFIG_ENV_IS_IN_FLASH
 	   and CONFIG_ENV_SECT_SIZE, you can specify to use only a part
 	   of this flash sector for the environment. This saves
 	   memory for the RAM copy of the environment.

 	   It may also save flash memory if you decide to use this
 	   when your environment is "embedded" within U-Boot code,
 	   since then the remainder of the flash sector could be used
 	   for U-Boot code. It should be pointed out that this is
 	   STRONGLY DISCOURAGED from a robustness point of view:
 	   updating the environment in flash makes it always
 	   necessary to erase the WHOLE sector. If something goes
 	   wrong before the contents has been restored from a copy in
 	   RAM, your target system will be dead.

 	  CONFIG_ENV_ADDR_REDUND
 	  CONFIG_ENV_SIZE_REDUND

 	   These settings describe a second storage area used to hold
 	   a redundant copy of the environment data, so that there is
 	   a valid backup copy in case there is a power failure during
 	   a "saveenv" operation.

 	  BE CAREFUL! Any changes to the flash layout, and some changes to the
 	  source code will make it necessary to adapt <board>/u-boot.lds*
 	  accordingly!

 config ENV_IS_IN_MMC

 	help
 	  Define this if you have an MMC device which you want to use for the
 	  environment.

 	  CONFIG_SYS_MMC_ENV_DEV:

 	  Specifies which MMC device the environment is stored in.

 	  CONFIG_SYS_MMC_ENV_PART (optional):

 	  Specifies which MMC partition the environment is stored in. If not
 	  set, defaults to partition 0, the user area. Common values might be
 	  1 (first MMC boot partition), 2 (second MMC boot partition).

 	  CONFIG_ENV_OFFSET:
 	  CONFIG_ENV_SIZE:

 	  These two #defines specify the offset and size of the environment
 	  area within the specified MMC device.

 	  If offset is positive (the usual case), it is treated as relative to
 	  the start of the MMC partition. If offset is negative, it is treated
 	  as relative to the end of the MMC partition. This can be useful if
 	  your board may be fitted with different MMC devices, which have
 	  different sizes for the MMC partitions, and you always want the
 	  environment placed at the very end of the partition, to leave the
 	  maximum possible space before it, to store other data.

 	  These two values are in units of bytes, but must be aligned to an
 	  MMC sector boundary.

 	  CONFIG_ENV_OFFSET_REDUND (optional):

 	  Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
 	  hold a redundant copy of the environment data. This provides a
 	  valid backup copy in case the other copy is corrupted, e.g. due
 	  to a power failure during a "saveenv" operation.

 	  This value may also be positive or negative; this is handled in the
 	  same way as CONFIG_ENV_OFFSET.

 	  This value is also in units of bytes, but must also be aligned to
 	  an MMC sector boundary.

 	  CONFIG_ENV_SIZE_REDUND (optional):

 	  This value need not be set, even when CONFIG_ENV_OFFSET_REDUND is
 	  set. If this value is set, it must be set to the same value as
 	  CONFIG_ENV_SIZE.

 config ENV_IS_IN_NAND
 	bool "Environment in a NAND device"
 	depends on !CHAIN_OF_TRUST
 	help
 	  Define this if you have a NAND device which you want to use for the
 	  environment.

 	  - CONFIG_ENV_OFFSET:
 	  - CONFIG_ENV_SIZE:

 	  These two #defines specify the offset and size of the environment
 	  area within the first NAND device.  CONFIG_ENV_OFFSET must be
 	  aligned to an erase block boundary.

 	  - CONFIG_ENV_OFFSET_REDUND (optional):

 	  This setting describes a second storage area of CONFIG_ENV_SIZE
 	  size used to hold a redundant copy of the environment data, so
 	  that there is a valid backup copy in case there is a power failure
 	  during a "saveenv" operation.	 CONFIG_ENV_OFFSET_REDUND must be
 	  aligned to an erase block boundary.

 	  - CONFIG_ENV_RANGE (optional):

 	  Specifies the length of the region in which the environment
 	  can be written.  This should be a multiple of the NAND device's
 	  block size.  Specifying a range with more erase blocks than
 	  are needed to hold CONFIG_ENV_SIZE allows bad blocks within
 	  the range to be avoided.

 	  - CONFIG_ENV_OFFSET_OOB (optional):

 	  Enables support for dynamically retrieving the offset of the
 	  environment from block zero's out-of-band data.  The
 	  "nand env.oob" command can be used to record this offset.
 	  Currently, CONFIG_ENV_OFFSET_REDUND is not supported when
 	  using CONFIG_ENV_OFFSET_OOB.

 config ENV_IS_IN_NVRAM
 	bool "Environment in a non-volatile RAM"
 	depends on !CHAIN_OF_TRUST
 	help
 	  Define this if you have some non-volatile memory device
 	  (NVRAM, battery buffered SRAM) which you want to use for the
 	  environment.

 	  - CONFIG_ENV_ADDR:
 	  - CONFIG_ENV_SIZE:

 	  These two #defines are used to determine the memory area you
 	  want to use for environment. It is assumed that this memory
 	  can just be read and written to, without any special
 	  provision.

 config ENV_IS_IN_ONENAND
 	bool "Environment is in OneNAND"
 	depends on !CHAIN_OF_TRUST
 	help
 	  Define this if you want to put your local device's environment in
 	  OneNAND.

	Define this if you have a flash device which you want to use for the
	environment.

	a) The environment occupies one whole flash sector, which is
	"embedded" in the text segment with the U-Boot code. This
	happens usually with "bottom boot sector" or "top boot
	sector" type flash chips, which have several smaller
	sectors at the start or the end. For instance, such a
	layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
	such a case you would place the environment in one of the
	4 kB sectors - with U-Boot code before and after it. With
	"top boot sector" type flash chips, you would put the
	environment in one of the last sectors, leaving a gap
	between U-Boot and the environment.

	CONFIG_ENV_OFFSET:

	Offset of environment data (variable area) to the
	beginning of flash memory; for instance, with bottom boot
	type flash chips the second sector can be used: the offset
	for this sector is given here.

	CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE.

	CONFIG_ENV_ADDR:

	This is just another way to specify the start address of
	the flash sector containing the environment (instead of
	CONFIG_ENV_OFFSET).

	CONFIG_ENV_SECT_SIZE:

	Size of the sector containing the environment.


	b) Sometimes flash chips have few, equal sized, BIG sectors.
	In such a case you don't want to spend a whole sector for
	the environment.

	CONFIG_ENV_SIZE:

	If you use this in combination with CONFIG_ENV_IS_IN_FLASH
	and CONFIG_ENV_SECT_SIZE, you can specify to use only a part
	of this flash sector for the environment. This saves
	memory for the RAM copy of the environment.

	It may also save flash memory if you decide to use this
	when your environment is "embedded" within U-Boot code,
	since then the remainder of the flash sector could be used
	for U-Boot code. It should be pointed out that this is
	STRONGLY DISCOURAGED from a robustness point of view:
	updating the environment in flash makes it always
	necessary to erase the WHOLE sector. If something goes
	wrong before the contents has been restored from a copy in
	RAM, your target system will be dead.

	CONFIG_ENV_ADDR_REDUND
	CONFIG_ENV_SIZE_REDUND

	These settings describe a second storage area used to hold
	a redundant copy of the environment data, so that there is
	a valid backup copy in case there is a power failure during
	a "saveenv" operation.

	BE CAREFUL! Any changes to the flash layout, and some changes to the
	source code will make it necessary to adapt <board>/u-boot.lds*
	accordingly!

	CONFIG_SYS_MMC_ENV_DEV:

	Specifies which MMC device the environment is stored in.

	CONFIG_SYS_MMC_ENV_PART (optional):

	Specifies which MMC partition the environment is stored in. If not
	set, defaults to partition 0, the user area. Common values might be
	1 (first MMC boot partition), 2 (second MMC boot partition).

	CONFIG_ENV_OFFSET:
	CONFIG_ENV_SIZE:

	These two #defines specify the offset and size of the environment
	area within the specified MMC device.

	If offset is positive (the usual case), it is treated as relative to
	the start of the MMC partition. If offset is negative, it is treated
	as relative to the end of the MMC partition. This can be useful if
	your board may be fitted with different MMC devices, which have
	different sizes for the MMC partitions, and you always want the
	environment placed at the very end of the partition, to leave the
	maximum possible space before it, to store other data.

	These two values are in units of bytes, but must be aligned to an
	MMC sector boundary.

	CONFIG_ENV_OFFSET_REDUND (optional):

	Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
	hold a redundant copy of the environment data. This provides a
	valid backup copy in case the other copy is corrupted, e.g. due
	to a power failure during a "saveenv" operation.

	This value may also be positive or negative; this is handled in the
	same way as CONFIG_ENV_OFFSET.

	This value is also in units of bytes, but must also be aligned to
	an MMC sector boundary.

	CONFIG_ENV_SIZE_REDUND (optional):

	This value need not be set, even when CONFIG_ENV_OFFSET_REDUND is
	set. If this value is set, it must be set to the same value as
	CONFIG_ENV_SIZE.

	- CONFIG_ENV_OFFSET_REDUND (optional):

	This setting describes a second storage area of CONFIG_ENV_SIZE
	size used to hold a redundant copy of the environment data, so
	that there is a valid backup copy in case there is a power failure
	during a "saveenv" operation. CONFIG_ENV_OFFSET_REDUND must be
	aligned to an erase block boundary.

	- CONFIG_ENV_RANGE (optional):

	Specifies the length of the region in which the environment
	can be written. This should be a multiple of the NAND device's
	block size. Specifying a range with more erase blocks than
	are needed to hold CONFIG_ENV_SIZE allows bad blocks within
	the range to be avoided.

	- CONFIG_ENV_OFFSET_OOB (optional):

	Enables support for dynamically retrieving the offset of the
	environment from block zero's out-of-band data. The
	"nand env.oob" command can be used to record this offset.
	Currently, CONFIG_ENV_OFFSET_REDUND is not supported when
