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"
depends on !CHAIN_OF_TRUST
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
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
depends on MMC
default y if ARCH_EXYNOS4
default y if MX6SX || MX7D
default y if TEGRA30 || TEGRA124
default y if TEGRA_ARMV8_COMMON
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_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.
- CONFIG_ENV_ADDR:
- CONFIG_ENV_SIZE:
These two #defines are used to determine the device range 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_REMOTE
bool "Environment is in remote 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

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_SECT_SIZE_AUTO
bool "Use automatically detected sector size"
depends on ENV_IS_IN_SPI_FLASH
help
Some boards exist in multiple variants, with different
flashes having different sector sizes. In such cases, you
can select this option to make U-Boot use the actual sector
size when figuring out how much to erase, which can thus be
more efficient on the flashes with smaller erase size. Since
the environment must always be aligned on a sector boundary,
CONFIG_ENV_OFFSET must be aligned to the largest of the
different sector sizes, and CONFIG_ENV_SECT_SIZE should be
set to that value.

depends on MTD_UBI
depends on CMD_UBI
help
Define this if you have an UBI volume that you want to use for the
environment. This has the benefit of wear-leveling the environment
accesses, which is important on NAND.
- CONFIG_ENV_UBI_PART:
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 SYS_REDUNDAND_ENVIRONMENT
bool "Enable redundant environment support"
help
Normally, the environemt is stored in a single location. By
selecting this option, you can then define where 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.
Also this config changes the binary environment structure handling
which is used by env import/export commands which are independent of
storing variables to redundant location on a non volatile device.
