105 Define this if you have a flash device which you want to use for the
106 environment.
107
108 a) The environment occupies one whole flash sector, which is
109 "embedded" in the text segment with the U-Boot code. This
110 happens usually with "bottom boot sector" or "top boot
111 sector" type flash chips, which have several smaller
112 sectors at the start or the end. For instance, such a
113 layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
114 such a case you would place the environment in one of the
115 4 kB sectors - with U-Boot code before and after it. With
116 "top boot sector" type flash chips, you would put the
117 environment in one of the last sectors, leaving a gap
118 between U-Boot and the environment.
119
120 CONFIG_ENV_OFFSET:
121
122 Offset of environment data (variable area) to the
123 beginning of flash memory; for instance, with bottom boot
124 type flash chips the second sector can be used: the offset
125 for this sector is given here.
126
127 CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE.
128
129 CONFIG_ENV_ADDR:
130
131 This is just another way to specify the start address of
132 the flash sector containing the environment (instead of
133 CONFIG_ENV_OFFSET).
134
135 CONFIG_ENV_SECT_SIZE:
136
137 Size of the sector containing the environment.
138
139
140 b) Sometimes flash chips have few, equal sized, BIG sectors.
141 In such a case you don't want to spend a whole sector for
142 the environment.
143
144 CONFIG_ENV_SIZE:
145
146 If you use this in combination with CONFIG_ENV_IS_IN_FLASH
147 and CONFIG_ENV_SECT_SIZE, you can specify to use only a part
148 of this flash sector for the environment. This saves
149 memory for the RAM copy of the environment.
150
151 It may also save flash memory if you decide to use this
152 when your environment is "embedded" within U-Boot code,
153 since then the remainder of the flash sector could be used
154 for U-Boot code. It should be pointed out that this is
155 STRONGLY DISCOURAGED from a robustness point of view:
156 updating the environment in flash makes it always
157 necessary to erase the WHOLE sector. If something goes
158 wrong before the contents has been restored from a copy in
159 RAM, your target system will be dead.
160
161 CONFIG_ENV_ADDR_REDUND
Simon Glass0649cd02017-08-03 12:21:49 -0600162
163 These settings describe a second storage area used to hold
164 a redundant copy of the environment data, so that there is
165 a valid backup copy in case there is a power failure during
166 a "saveenv" operation.
167
168 BE CAREFUL! Any changes to the flash layout, and some changes to the
169 source code will make it necessary to adapt <board>/u-boot.lds*
170 accordingly!

187
188 CONFIG_SYS_MMC_ENV_PART (optional):
189
190 Specifies which MMC partition the environment is stored in. If not
191 set, defaults to partition 0, the user area. Common values might be
192 1 (first MMC boot partition), 2 (second MMC boot partition).
193
194 CONFIG_ENV_OFFSET:
195 CONFIG_ENV_SIZE:
196
197 These two #defines specify the offset and size of the environment
198 area within the specified MMC device.
199
200 If offset is positive (the usual case), it is treated as relative to
201 the start of the MMC partition. If offset is negative, it is treated
202 as relative to the end of the MMC partition. This can be useful if
203 your board may be fitted with different MMC devices, which have
204 different sizes for the MMC partitions, and you always want the
205 environment placed at the very end of the partition, to leave the
206 maximum possible space before it, to store other data.
207
208 These two values are in units of bytes, but must be aligned to an
209 MMC sector boundary.
210
211 CONFIG_ENV_OFFSET_REDUND (optional):
212
213 Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
214 hold a redundant copy of the environment data. This provides a
215 valid backup copy in case the other copy is corrupted, e.g. due
216 to a power failure during a "saveenv" operation.
217
218 This value may also be positive or negative; this is handled in the
219 same way as CONFIG_ENV_OFFSET.
220
Marek Vasutd11d1be2021-10-17 19:23:36 +0200221 In case CONFIG_SYS_MMC_ENV_PART is 1 (i.e. environment in eMMC boot
222 partition) then setting CONFIG_ENV_OFFSET_REDUND to the same value
223 as CONFIG_ENV_OFFSET makes use of the second eMMC boot partition for
224 the redundant environment copy.
