78 Define this if you have a flash device which you want to use for the
79 environment.
80
81 a) The environment occupies one whole flash sector, which is
82 "embedded" in the text segment with the U-Boot code. This
83 happens usually with "bottom boot sector" or "top boot
84 sector" type flash chips, which have several smaller
85 sectors at the start or the end. For instance, such a
86 layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
87 such a case you would place the environment in one of the
88 4 kB sectors - with U-Boot code before and after it. With
89 "top boot sector" type flash chips, you would put the
90 environment in one of the last sectors, leaving a gap
91 between U-Boot and the environment.
92
93 CONFIG_ENV_OFFSET:
94
95 Offset of environment data (variable area) to the
96 beginning of flash memory; for instance, with bottom boot
97 type flash chips the second sector can be used: the offset
98 for this sector is given here.
99
100 CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE.
101
102 CONFIG_ENV_ADDR:
103
104 This is just another way to specify the start address of
105 the flash sector containing the environment (instead of
106 CONFIG_ENV_OFFSET).
107
108 CONFIG_ENV_SECT_SIZE:
109
110 Size of the sector containing the environment.
111
112
113 b) Sometimes flash chips have few, equal sized, BIG sectors.
114 In such a case you don't want to spend a whole sector for
115 the environment.
116
117 CONFIG_ENV_SIZE:
118
119 If you use this in combination with CONFIG_ENV_IS_IN_FLASH
120 and CONFIG_ENV_SECT_SIZE, you can specify to use only a part
121 of this flash sector for the environment. This saves
122 memory for the RAM copy of the environment.
123
124 It may also save flash memory if you decide to use this
125 when your environment is "embedded" within U-Boot code,
126 since then the remainder of the flash sector could be used
127 for U-Boot code. It should be pointed out that this is
128 STRONGLY DISCOURAGED from a robustness point of view:
129 updating the environment in flash makes it always
130 necessary to erase the WHOLE sector. If something goes
131 wrong before the contents has been restored from a copy in
132 RAM, your target system will be dead.
133
134 CONFIG_ENV_ADDR_REDUND
135 CONFIG_ENV_SIZE_REDUND
136
137 These settings describe a second storage area used to hold
138 a redundant copy of the environment data, so that there is
139 a valid backup copy in case there is a power failure during
140 a "saveenv" operation.
141
142 BE CAREFUL! Any changes to the flash layout, and some changes to the
143 source code will make it necessary to adapt <board>/u-boot.lds*
144 accordingly!

155 Define this if you have an MMC device which you want to use for the
156 environment.
157
158 CONFIG_SYS_MMC_ENV_DEV:
159
160 Specifies which MMC device the environment is stored in.
161
162 CONFIG_SYS_MMC_ENV_PART (optional):
163
164 Specifies which MMC partition the environment is stored in. If not
165 set, defaults to partition 0, the user area. Common values might be
166 1 (first MMC boot partition), 2 (second MMC boot partition).
167
168 CONFIG_ENV_OFFSET:
169 CONFIG_ENV_SIZE:
170
171 These two #defines specify the offset and size of the environment
172 area within the specified MMC device.
173
174 If offset is positive (the usual case), it is treated as relative to
175 the start of the MMC partition. If offset is negative, it is treated
176 as relative to the end of the MMC partition. This can be useful if
177 your board may be fitted with different MMC devices, which have
178 different sizes for the MMC partitions, and you always want the
179 environment placed at the very end of the partition, to leave the
180 maximum possible space before it, to store other data.
181
182 These two values are in units of bytes, but must be aligned to an
183 MMC sector boundary.
184
185 CONFIG_ENV_OFFSET_REDUND (optional):
186
187 Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
188 hold a redundant copy of the environment data. This provides a
189 valid backup copy in case the other copy is corrupted, e.g. due
190 to a power failure during a "saveenv" operation.
191
192 This value may also be positive or negative; this is handled in the
193 same way as CONFIG_ENV_OFFSET.
194
195 This value is also in units of bytes, but must also be aligned to
196 an MMC sector boundary.
197
198 CONFIG_ENV_SIZE_REDUND (optional):
199
200 This value need not be set, even when CONFIG_ENV_OFFSET_REDUND is
201 set. If this value is set, it must be set to the same value as
202 CONFIG_ENV_SIZE.

223 during a "saveenv" operation. CONFIG_ENV_OFFSET_REDUND must be
224 aligned to an erase block boundary.
225
226 - CONFIG_ENV_RANGE (optional):
227
228 Specifies the length of the region in which the environment
229 can be written. This should be a multiple of the NAND device's
230 block size. Specifying a range with more erase blocks than
231 are needed to hold CONFIG_ENV_SIZE allows bad blocks within
232 the range to be avoided.
233
234 - CONFIG_ENV_OFFSET_OOB (optional):
235
236 Enables support for dynamically retrieving the offset of the
237 environment from block zero's out-of-band data. The
238 "nand env.oob" command can be used to record this offset.
239 Currently, CONFIG_ENV_OFFSET_REDUND is not supported when
