19	  on a storage medium. In this case the environment will still exist

31	  - CONFIG_ENV_OFFSET:

48	  EEPROM. For example:
49
50	  #define CONFIG_I2C_ENV_EEPROM_BUS	  1

83	help
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
141	  CONFIG_ENV_SIZE_REDUND
142
143	   These settings describe a second storage area used to hold
144	   a redundant copy of the environment data, so that there is
145	   a valid backup copy in case there is a power failure during
146	   a "saveenv" operation.
147
148	  BE CAREFUL! Any changes to the flash layout, and some changes to the
149	  source code will make it necessary to adapt <board>/u-boot.lds*
150	  accordingly!
151
152config ENV_IS_IN_MMC
153	bool "Environment in an MMC device"
154	depends on !CHAIN_OF_TRUST
155	depends on MMC
156	default y if ARCH_EXYNOS4
157	default y if MX6SX || MX7D
158	default y if TEGRA30 || TEGRA124
159	default y if TEGRA_ARMV8_COMMON
160	help
161	  Define this if you have an MMC device which you want to use for the
162	  environment.
163
164	  CONFIG_SYS_MMC_ENV_DEV:
165
166	  Specifies which MMC device the environment is stored in.
167
168	  CONFIG_SYS_MMC_ENV_PART (optional):
169
170	  Specifies which MMC partition the environment is stored in. If not
171	  set, defaults to partition 0, the user area. Common values might be
172	  1 (first MMC boot partition), 2 (second MMC boot partition).
173
174	  CONFIG_ENV_OFFSET:
175	  CONFIG_ENV_SIZE:
176
177	  These two #defines specify the offset and size of the environment
178	  area within the specified MMC device.
179
180	  If offset is positive (the usual case), it is treated as relative to
181	  the start of the MMC partition. If offset is negative, it is treated
182	  as relative to the end of the MMC partition. This can be useful if
183	  your board may be fitted with different MMC devices, which have
184	  different sizes for the MMC partitions, and you always want the
185	  environment placed at the very end of the partition, to leave the
186	  maximum possible space before it, to store other data.
187
188	  These two values are in units of bytes, but must be aligned to an
189	  MMC sector boundary.
190
191	  CONFIG_ENV_OFFSET_REDUND (optional):
192
193	  Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
194	  hold a redundant copy of the environment data. This provides a
195	  valid backup copy in case the other copy is corrupted, e.g. due
196	  to a power failure during a "saveenv" operation.
197
198	  This value may also be positive or negative; this is handled in the
199	  same way as CONFIG_ENV_OFFSET.
200
201	  This value is also in units of bytes, but must also be aligned to
202	  an MMC sector boundary.
203
204	  CONFIG_ENV_SIZE_REDUND (optional):
205
206	  This value need not be set, even when CONFIG_ENV_OFFSET_REDUND is
207	  set. If this value is set, it must be set to the same value as
208	  CONFIG_ENV_SIZE.
209
210config ENV_IS_IN_NAND
211	bool "Environment in a NAND device"
212	depends on !CHAIN_OF_TRUST
213	help
214	  Define this if you have a NAND device which you want to use for the
215	  environment.
216
217	  - CONFIG_ENV_OFFSET:
218	  - CONFIG_ENV_SIZE:
219
220	  These two #defines specify the offset and size of the environment
221	  area within the first NAND device.  CONFIG_ENV_OFFSET must be
222	  aligned to an erase block boundary.
223
224	  - CONFIG_ENV_OFFSET_REDUND (optional):
225
226	  This setting describes a second storage area of CONFIG_ENV_SIZE
227	  size used to hold a redundant copy of the environment data, so
228	  that there is a valid backup copy in case there is a power failure
229	  during a "saveenv" operation.	 CONFIG_ENV_OFFSET_REDUND must be
230	  aligned to an erase block boundary.
231
232	  - CONFIG_ENV_RANGE (optional):
233
234	  Specifies the length of the region in which the environment
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
244	  "nand env.oob" command can be used to record this offset.
245	  Currently, CONFIG_ENV_OFFSET_REDUND is not supported when
246	  using CONFIG_ENV_OFFSET_OOB.
