84 Define this if you have a flash device which you want to use for the
85 environment.
86
87 a) The environment occupies one whole flash sector, which is
88 "embedded" in the text segment with the U-Boot code. This
89 happens usually with "bottom boot sector" or "top boot
90 sector" type flash chips, which have several smaller
91 sectors at the start or the end. For instance, such a
92 layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
93 such a case you would place the environment in one of the
94 4 kB sectors - with U-Boot code before and after it. With
95 "top boot sector" type flash chips, you would put the
96 environment in one of the last sectors, leaving a gap
97 between U-Boot and the environment.
98
99 CONFIG_ENV_OFFSET:
100
101 Offset of environment data (variable area) to the
102 beginning of flash memory; for instance, with bottom boot
103 type flash chips the second sector can be used: the offset
104 for this sector is given here.
105
106 CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE.
107
108 CONFIG_ENV_ADDR:
109
110 This is just another way to specify the start address of
111 the flash sector containing the environment (instead of
112 CONFIG_ENV_OFFSET).
113
114 CONFIG_ENV_SECT_SIZE:
115
116 Size of the sector containing the environment.
117
118
119 b) Sometimes flash chips have few, equal sized, BIG sectors.
120 In such a case you don't want to spend a whole sector for
121 the environment.
122
123 CONFIG_ENV_SIZE:
124
125 If you use this in combination with CONFIG_ENV_IS_IN_FLASH
126 and CONFIG_ENV_SECT_SIZE, you can specify to use only a part
127 of this flash sector for the environment. This saves
128 memory for the RAM copy of the environment.
129
130 It may also save flash memory if you decide to use this
131 when your environment is "embedded" within U-Boot code,
132 since then the remainder of the flash sector could be used
133 for U-Boot code. It should be pointed out that this is
134 STRONGLY DISCOURAGED from a robustness point of view:
135 updating the environment in flash makes it always
136 necessary to erase the WHOLE sector. If something goes
137 wrong before the contents has been restored from a copy in
138 RAM, your target system will be dead.
139
140 CONFIG_ENV_ADDR_REDUND
Simon Glass547cb402017-08-03 12:21:49 -0600141
142 These settings describe a second storage area used to hold
143 a redundant copy of the environment data, so that there is
144 a valid backup copy in case there is a power failure during
145 a "saveenv" operation.
146
147 BE CAREFUL! Any changes to the flash layout, and some changes to the
148 source code will make it necessary to adapt <board>/u-boot.lds*
149 accordingly!

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

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