34 Use this if you have an EEPROM or similar serial access
35 device and a driver for it.
40 These two #defines specify the offset and size of the
41 environment area within the total memory of your EEPROM.
43 Note that we consider the length of the address field to
44 still be one byte because the extra address bits are hidden

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

166 CONFIG_SYS_MMC_ENV_DEV:
168 Specifies which MMC device the environment is stored in.
170 CONFIG_SYS_MMC_ENV_PART (optional):
172 Specifies which MMC partition the environment is stored in. If not
173 set, defaults to partition 0, the user area. Common values might be
174 1 (first MMC boot partition), 2 (second MMC boot partition).
179 These two #defines specify the offset and size of the environment
180 area within the specified MMC device.
182 If offset is positive (the usual case), it is treated as relative to
183 the start of the MMC partition. If offset is negative, it is treated
184 as relative to the end of the MMC partition. This can be useful if
185 your board may be fitted with different MMC devices, which have
186 different sizes for the MMC partitions, and you always want the
187 environment placed at the very end of the partition, to leave the
188 maximum possible space before it, to store other data.
190 These two values are in units of bytes, but must be aligned to an
193 CONFIG_ENV_OFFSET_REDUND (optional):
195 Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
196 hold a redundant copy of the environment data. This provides a
197 valid backup copy in case the other copy is corrupted, e.g. due
198 to a power failure during a "saveenv" operation.
200 This value may also be positive or negative; this is handled in the
201 same way as CONFIG_ENV_OFFSET.
203 In case CONFIG_SYS_MMC_ENV_PART is 1 (i.e. environment in eMMC boot
204 partition) then setting CONFIG_ENV_OFFSET_REDUND to the same value
205 as CONFIG_ENV_OFFSET makes use of the second eMMC boot partition for
206 the redundant environment copy.
208 This value is also in units of bytes, but must also be aligned to
209 an MMC sector boundary.

215 Define this if you have a NAND device which you want to use for the

222 area within the first NAND device. CONFIG_ENV_OFFSET must be
223 aligned to an erase block boundary.
225 - CONFIG_ENV_OFFSET_REDUND (optional):
227 This setting describes a second storage area of CONFIG_ENV_SIZE
228 size used to hold a redundant copy of the environment data, so
229 that there is a valid backup copy in case there is a power failure
230 during a "saveenv" operation. CONFIG_ENV_OFFSET_REDUND must be
231 aligned to an erase block boundary.
233 - CONFIG_ENV_RANGE (optional):
235 Specifies the length of the region in which the environment
236 can be written. This should be a multiple of the NAND device's
237 block size. Specifying a range with more erase blocks than
238 are needed to hold CONFIG_ENV_SIZE allows bad blocks within
239 the range to be avoided.
241 - CONFIG_ENV_OFFSET_OOB (optional):
243 Enables support for dynamically retrieving the offset of the
244 environment from block zero's out-of-band data. The
245 "nand env.oob" command can be used to record this offset.
246 Currently, CONFIG_ENV_OFFSET_REDUND is not supported when
247 using CONFIG_ENV_OFFSET_OOB.

284 Define this if you have a remote memory space which you
285 want to use for the local device's environment.
290 These two #defines specify the address and size of the

293 space by SRIO or PCIE links.

314 aligned to an erase sector boundary.

322 This setting describes a second storage area of CONFIG_ENV_SIZE
323 size used to hold a redundant copy of the environment data, so
324 that there is a valid backup copy in case there is a power failure
325 during a "saveenv" operation. CONFIG_ENV_OFFSET_REDUND must be
326 aligned to an erase sector boundary.

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

423 Define this to the name of another volume to store a second copy of
424 the environment in. This will enable redundant environments in UBI.
425 It is assumed that both volumes are in the same MTD partition.

428 bool "Enable redundant environment support"
430 Normally, the environemt is stored in a single location. By

432 copy of the environment data, so that there is a valid backup copy in
433 case there is a power failure during a "saveenv" operation.
