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

  78           Define this if you have a flash device which you want to use for the
  79           environment.
  80
  81           a) The environment occupies one whole flash sector, which is
  82            "embedded" in the text segment with the U-Boot code. This
  83            happens usually with "bottom boot sector" or "top boot
  84            sector" type flash chips, which have several smaller
  85            sectors at the start or the end. For instance, such a
  86            layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
  87            such a case you would place the environment in one of the
  88            4 kB sectors - with U-Boot code before and after it. With
  89            "top boot sector" type flash chips, you would put the
  90            environment in one of the last sectors, leaving a gap
  91            between U-Boot and the environment.
  92
  93           CONFIG_ENV_OFFSET:
  94
  95            Offset of environment data (variable area) to the
  96            beginning of flash memory; for instance, with bottom boot
  97            type flash chips the second sector can be used: the offset
  98            for this sector is given here.
  99
 100            CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE.
 101
 102           CONFIG_ENV_ADDR:
 103
 104            This is just another way to specify the start address of
 105            the flash sector containing the environment (instead of
 106            CONFIG_ENV_OFFSET).
 107
 108           CONFIG_ENV_SECT_SIZE:
 109
 110            Size of the sector containing the environment.
 111
 112
 113           b) Sometimes flash chips have few, equal sized, BIG sectors.
 114            In such a case you don't want to spend a whole sector for
 115            the environment.
 116
 117           CONFIG_ENV_SIZE:
 118
 119            If you use this in combination with CONFIG_ENV_IS_IN_FLASH
 120            and CONFIG_ENV_SECT_SIZE, you can specify to use only a part
 121            of this flash sector for the environment. This saves
 122            memory for the RAM copy of the environment.
 123
 124            It may also save flash memory if you decide to use this
 125            when your environment is "embedded" within U-Boot code,
 126            since then the remainder of the flash sector could be used
 127            for U-Boot code. It should be pointed out that this is
 128            STRONGLY DISCOURAGED from a robustness point of view:
 129            updating the environment in flash makes it always
 130            necessary to erase the WHOLE sector. If something goes
 131            wrong before the contents has been restored from a copy in
 132            RAM, your target system will be dead.
 133
 134           CONFIG_ENV_ADDR_REDUND
 135           CONFIG_ENV_SIZE_REDUND
 136
 137            These settings describe a second storage area used to hold
 138            a redundant copy of the environment data, so that there is
 139            a valid backup copy in case there is a power failure during
 140            a "saveenv" operation.
 141
 142           BE CAREFUL! Any changes to the flash layout, and some changes to the
 143           source code will make it necessary to adapt <board>/u-boot.lds*
 144           accordingly!

 156           environment.
 157
 158           CONFIG_SYS_MMC_ENV_DEV:
 159
 160           Specifies which MMC device the environment is stored in.
 161
 162           CONFIG_SYS_MMC_ENV_PART (optional):
 163
 164           Specifies which MMC partition the environment is stored in. If not
 165           set, defaults to partition 0, the user area. Common values might be
 166           1 (first MMC boot partition), 2 (second MMC boot partition).
 167
 168           CONFIG_ENV_OFFSET:
 169           CONFIG_ENV_SIZE:
 170
 171           These two #defines specify the offset and size of the environment
 172           area within the specified MMC device.
 173
 174           If offset is positive (the usual case), it is treated as relative to
 175           the start of the MMC partition. If offset is negative, it is treated
 176           as relative to the end of the MMC partition. This can be useful if
 177           your board may be fitted with different MMC devices, which have
 178           different sizes for the MMC partitions, and you always want the
 179           environment placed at the very end of the partition, to leave the
 180           maximum possible space before it, to store other data.
 181
 182           These two values are in units of bytes, but must be aligned to an
 183           MMC sector boundary.
 184
 185           CONFIG_ENV_OFFSET_REDUND (optional):
 186
 187           Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
 188           hold a redundant copy of the environment data. This provides a
 189           valid backup copy in case the other copy is corrupted, e.g. due
 190           to a power failure during a "saveenv" operation.
 191
 192           This value may also be positive or negative; this is handled in the
 193           same way as CONFIG_ENV_OFFSET.
 194
 195           This value is also in units of bytes, but must also be aligned to
 196           an MMC sector boundary.
 197
 198           CONFIG_ENV_SIZE_REDUND (optional):
 199
 200           This value need not be set, even when CONFIG_ENV_OFFSET_REDUND is
 201           set. If this value is set, it must be set to the same value as
 202           CONFIG_ENV_SIZE.

 227

 229           can be written.  This should be a multiple of the NAND device's
 230           block size.  Specifying a range with more erase blocks than
 231           are needed to hold CONFIG_ENV_SIZE allows bad blocks within
 232           the range to be avoided.
