+ bool "Environment in flash memory"

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

+
+ 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

+ BE CAREFUL! Any changes to the flash layout, and some changes to the
