81 Define this if you have a flash device which you want to use for the
82 environment.
83
84 a) The environment occupies one whole flash sector, which is
85 "embedded" in the text segment with the U-Boot code. This
86 happens usually with "bottom boot sector" or "top boot
87 sector" type flash chips, which have several smaller
88 sectors at the start or the end. For instance, such a
89 layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
90 such a case you would place the environment in one of the
91 4 kB sectors - with U-Boot code before and after it. With
92 "top boot sector" type flash chips, you would put the
93 environment in one of the last sectors, leaving a gap
94 between U-Boot and the environment.
95
96 CONFIG_ENV_OFFSET:
97
98 Offset of environment data (variable area) to the
99 beginning of flash memory; for instance, with bottom boot
100 type flash chips the second sector can be used: the offset
101 for this sector is given here.
102
103 CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE.
104
105 CONFIG_ENV_ADDR:
106
107 This is just another way to specify the start address of
108 the flash sector containing the environment (instead of
109 CONFIG_ENV_OFFSET).
110
111 CONFIG_ENV_SECT_SIZE:
112
113 Size of the sector containing the environment.
114
115
116 b) Sometimes flash chips have few, equal sized, BIG sectors.
117 In such a case you don't want to spend a whole sector for
118 the environment.
119
120 CONFIG_ENV_SIZE:
121
122 If you use this in combination with CONFIG_ENV_IS_IN_FLASH
123 and CONFIG_ENV_SECT_SIZE, you can specify to use only a part
124 of this flash sector for the environment. This saves
125 memory for the RAM copy of the environment.
126
127 It may also save flash memory if you decide to use this
128 when your environment is "embedded" within U-Boot code,
129 since then the remainder of the flash sector could be used
130 for U-Boot code. It should be pointed out that this is
131 STRONGLY DISCOURAGED from a robustness point of view:
132 updating the environment in flash makes it always
133 necessary to erase the WHOLE sector. If something goes
134 wrong before the contents has been restored from a copy in
135 RAM, your target system will be dead.
136
137 CONFIG_ENV_ADDR_REDUND
Simon Glass547cb402017-08-03 12:21:49 -0600138
139 These settings describe a second storage area used to hold
140 a redundant copy of the environment data, so that there is
141 a valid backup copy in case there is a power failure during
142 a "saveenv" operation.
143
144 BE CAREFUL! Any changes to the flash layout, and some changes to the
145 source code will make it necessary to adapt <board>/u-boot.lds*
146 accordingly!

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

224 Specifies the length of the region in which the environment
225 can be written. This should be a multiple of the NAND device's
226 block size. Specifying a range with more erase blocks than
227 are needed to hold CONFIG_ENV_SIZE allows bad blocks within
228 the range to be avoided.
229
230 - CONFIG_ENV_OFFSET_OOB (optional):
231
232 Enables support for dynamically retrieving the offset of the
233 environment from block zero's out-of-band data. The
234 "nand env.oob" command can be used to record this offset.

454 be as following:
455
456 "D:P", "D:0", "D", "D:" or "D:auto" (D, P are integers. And P >= 1)
457 - "D:P": device D partition P. Error occurs if device D has no
458 partition table.
459 - "D:0": device D.
460 - "D" or "D:": device D partition 1 if device D has partition
461 table, or the whole device D if has no partition
462 table.
463 - "D:auto": first partition in device D with bootable flag set.
464 If none, first valid partition in device D. If no
465 partition table then means device D.
