91 Define this if you have a flash device which you want to use for the
92 environment.
93
94 a) The environment occupies one whole flash sector, which is
95 "embedded" in the text segment with the U-Boot code. This
96 happens usually with "bottom boot sector" or "top boot
97 sector" type flash chips, which have several smaller
98 sectors at the start or the end. For instance, such a
99 layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
100 such a case you would place the environment in one of the
101 4 kB sectors - with U-Boot code before and after it. With
102 "top boot sector" type flash chips, you would put the
103 environment in one of the last sectors, leaving a gap
104 between U-Boot and the environment.
105
106 CONFIG_ENV_OFFSET:
107
108 Offset of environment data (variable area) to the
109 beginning of flash memory; for instance, with bottom boot
110 type flash chips the second sector can be used: the offset
111 for this sector is given here.
112
113 CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE.
114
115 CONFIG_ENV_ADDR:
116
117 This is just another way to specify the start address of
118 the flash sector containing the environment (instead of
119 CONFIG_ENV_OFFSET).
120
121 CONFIG_ENV_SECT_SIZE:
122
123 Size of the sector containing the environment.
124
125
126 b) Sometimes flash chips have few, equal sized, BIG sectors.
127 In such a case you don't want to spend a whole sector for
128 the environment.
129
130 CONFIG_ENV_SIZE:
131
132 If you use this in combination with CONFIG_ENV_IS_IN_FLASH
133 and CONFIG_ENV_SECT_SIZE, you can specify to use only a part
134 of this flash sector for the environment. This saves
135 memory for the RAM copy of the environment.
136
137 It may also save flash memory if you decide to use this
138 when your environment is "embedded" within U-Boot code,
139 since then the remainder of the flash sector could be used
140 for U-Boot code. It should be pointed out that this is
141 STRONGLY DISCOURAGED from a robustness point of view:
142 updating the environment in flash makes it always
143 necessary to erase the WHOLE sector. If something goes
144 wrong before the contents has been restored from a copy in
145 RAM, your target system will be dead.
146
147 CONFIG_ENV_ADDR_REDUND
Simon Glass547cb402017-08-03 12:21:49 -0600148
149 These settings describe a second storage area used to hold
150 a redundant copy of the environment data, so that there is
151 a valid backup copy in case there is a power failure during
152 a "saveenv" operation.
153
154 BE CAREFUL! Any changes to the flash layout, and some changes to the
155 source code will make it necessary to adapt <board>/u-boot.lds*
156 accordingly!

169
170 CONFIG_SYS_MMC_ENV_DEV:
171
172 Specifies which MMC device the environment is stored in.
173
174 CONFIG_SYS_MMC_ENV_PART (optional):
175
176 Specifies which MMC partition the environment is stored in. If not
177 set, defaults to partition 0, the user area. Common values might be
178 1 (first MMC boot partition), 2 (second MMC boot partition).
179
180 CONFIG_ENV_OFFSET:
181 CONFIG_ENV_SIZE:
182
183 These two #defines specify the offset and size of the environment
184 area within the specified MMC device.
185
186 If offset is positive (the usual case), it is treated as relative to
187 the start of the MMC partition. If offset is negative, it is treated
188 as relative to the end of the MMC partition. This can be useful if
189 your board may be fitted with different MMC devices, which have
190 different sizes for the MMC partitions, and you always want the
191 environment placed at the very end of the partition, to leave the
192 maximum possible space before it, to store other data.
193
194 These two values are in units of bytes, but must be aligned to an
195 MMC sector boundary.
196
197 CONFIG_ENV_OFFSET_REDUND (optional):
198
199 Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
200 hold a redundant copy of the environment data. This provides a
201 valid backup copy in case the other copy is corrupted, e.g. due
202 to a power failure during a "saveenv" operation.
203
204 This value may also be positive or negative; this is handled in the
205 same way as CONFIG_ENV_OFFSET.
206
207 This value is also in units of bytes, but must also be aligned to
208 an MMC sector boundary.

235 can be written. This should be a multiple of the NAND device's
236 block size. Specifying a range with more erase blocks than
237 are needed to hold CONFIG_ENV_SIZE allows bad blocks within
238 the range to be avoided.
239
240 - CONFIG_ENV_OFFSET_OOB (optional):
241
242 Enables support for dynamically retrieving the offset of the
243 environment from block zero's out-of-band data. The
