-- CONFIG_ENV_IS_IN_FLASH:
-
-       Define this if the environment is in flash memory.
-
-       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

-
-       - CONFIG_SYS_I2C_EEPROM_ADDR:

-

-
-       - CONFIG_SYS_I2C_EEPROM_ADDR_LEN:

-         that this is NOT the chip address length!
-
-       - CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW:
-         EEPROM chips that implement "address overflow" are ones
-         like Catalyst 24WC04/08/16 which has 9/10/11 bits of
-         address and the extra bits end up in the "chip address" bit
-         slots. This makes a 24WC08 (1Kbyte) chip look like four 256
-         byte chips.
-
-         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_SYS_EEPROM_SIZE:

-         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.
