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.

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_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.

|
|

|
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.
|
|

Enable this to inhibit loading the environment during board

initialization. This can address the security risk of untrusted data
|
|
being used during boot. Normally the environment is loaded when the
|
|
board is initialised so that it is available to U-Boot. This inhibits
|
|
that so that the environment is not available until explicitly loaded
|
|
later by U-Boot code. With CONFIG_OF_CONTROL this is instead
|
|
controlled by the value of /config/load-environment.
