Move environment files from common/ to env/

About a quarter of the files in common/ relate to the environment. It
seems better to put these into their own subdirectory and remove the
prefix.

-config ENV_IS_IN_FLASH
-	bool "Environment in flash memory"
-	depends on !CHAIN_OF_TRUST
-	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
-	bool "Environment in an MMC device"
-	depends on !CHAIN_OF_TRUST
-	default y if ARCH_SUNXI
-	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_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.

+

+
+	  EEPROM which holds the environment, is reached over
+	  a pca9547 i2c mux with address 0x70, channel 3.
+
+config ENV_IS_IN_FAT
+	bool "Environment is in a FAT filesystem"
+	depends on !CHAIN_OF_TRUST
+	select FAT_WRITE
+	help
+         Define this if you want to use the FAT file system for the environment.
+
+
+         - CONFIG_FAT_WRITE:
+         This must be enabled. Otherwise it cannot save the environment file.
+
+config ENV_IS_IN_FLASH
+	bool "Environment in flash memory"
+	depends on !CHAIN_OF_TRUST
+	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
+	bool "Environment in an MMC device"
+	depends on !CHAIN_OF_TRUST
+	default y if ARCH_SUNXI
+	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.

+	  provision.
+
+config ENV_IS_IN_REMOTE
+	bool "Environment is in remove memory space"
+	depends on !CHAIN_OF_TRUST
+	help
+	  Define this if you have a remote memory space which you
+	  want to use for the local device's environment.
+
+	  - CONFIG_ENV_ADDR:
+	  - CONFIG_ENV_SIZE:
+
+	  These two #defines specify the address and size of the
+	  environment area within the remote memory space. The
+	  local device can get the environment from remote memory
+	  space by SRIO or PCIE links.
+
+config ENV_IS_IN_SPI_FLASH
+	bool "Environment is in SPI flash"
+	depends on !CHAIN_OF_TRUST
+	help
+	  Define this if you have a SPI Flash memory 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 SPI Flash. CONFIG_ENV_OFFSET must be
+	  aligned to an erase sector boundary.
+
+	  - CONFIG_ENV_SECT_SIZE:
+
+	  Define the SPI flash's sector 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 sector boundary.
+
+	  - CONFIG_ENV_SPI_BUS (optional):
+	  - CONFIG_ENV_SPI_CS (optional):
+
+	  Define the SPI bus and chip select. If not defined they will be 0.
+
+	  - CONFIG_ENV_SPI_MAX_HZ (optional):
+
+	  Define the SPI max work clock. If not defined then use 1MHz.
+
+	  - CONFIG_ENV_SPI_MODE (optional):

+
+config ENV_IS_IN_UBI

+	  Define this to a string that is the mtd partition containing the UBI.
+
+	  - CONFIG_ENV_UBI_VOLUME:
+
+	  Define this to the name of the volume that you want to store the
+	  environment in.
+
+	  - CONFIG_ENV_UBI_VOLUME_REDUND:
+
+	  Define this to the name of another volume to store a second copy of
+	  the environment in.  This will enable redundant environments in UBI.
+	  It is assumed that both volumes are in the same MTD partition.
+
+	  - CONFIG_UBI_SILENCE_MSG
+	  - CONFIG_UBIFS_SILENCE_MSG
+
