| 256 | bool "Environment in flash memory" |
| 257 | depends on !CHAIN_OF_TRUST |
| 258 | help |
| 259 | Define this if you have a flash device which you want to use for the |
| 260 | environment. |
| 261 | |
| 262 | a) The environment occupies one whole flash sector, which is |
| 263 | "embedded" in the text segment with the U-Boot code. This |
| 264 | happens usually with "bottom boot sector" or "top boot |
| 265 | sector" type flash chips, which have several smaller |
| 266 | sectors at the start or the end. For instance, such a |
| 267 | layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In |
| 268 | such a case you would place the environment in one of the |
| 269 | 4 kB sectors - with U-Boot code before and after it. With |
| 270 | "top boot sector" type flash chips, you would put the |
| 271 | environment in one of the last sectors, leaving a gap |
| 272 | between U-Boot and the environment. |
| 273 | |
| 274 | CONFIG_ENV_OFFSET: |
| 275 | |
| 276 | Offset of environment data (variable area) to the |
| 277 | beginning of flash memory; for instance, with bottom boot |
| 278 | type flash chips the second sector can be used: the offset |
| 279 | for this sector is given here. |
| 280 | |
| 281 | CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE. |
| 282 | |
| 283 | CONFIG_ENV_ADDR: |
| 284 | |
| 285 | This is just another way to specify the start address of |
| 286 | the flash sector containing the environment (instead of |
| 287 | CONFIG_ENV_OFFSET). |
| 288 | |
| 289 | CONFIG_ENV_SECT_SIZE: |
| 290 | |
| 291 | Size of the sector containing the environment. |
| 292 | |
| 293 | |
| 294 | b) Sometimes flash chips have few, equal sized, BIG sectors. |
| 295 | In such a case you don't want to spend a whole sector for |
| 296 | the environment. |
| 297 | |
| 298 | CONFIG_ENV_SIZE: |
| 299 | |
| 300 | If you use this in combination with CONFIG_ENV_IS_IN_FLASH |
| 301 | and CONFIG_ENV_SECT_SIZE, you can specify to use only a part |
| 302 | of this flash sector for the environment. This saves |
| 303 | memory for the RAM copy of the environment. |
| 304 | |
| 305 | It may also save flash memory if you decide to use this |
| 306 | when your environment is "embedded" within U-Boot code, |
| 307 | since then the remainder of the flash sector could be used |
| 308 | for U-Boot code. It should be pointed out that this is |
| 309 | STRONGLY DISCOURAGED from a robustness point of view: |
| 310 | updating the environment in flash makes it always |
| 311 | necessary to erase the WHOLE sector. If something goes |
| 312 | wrong before the contents has been restored from a copy in |
| 313 | RAM, your target system will be dead. |
| 314 | |
| 315 | CONFIG_ENV_ADDR_REDUND |
| 316 | CONFIG_ENV_SIZE_REDUND |
| 317 | |
| 318 | These settings describe a second storage area used to hold |
| 319 | a redundant copy of the environment data, so that there is |
| 320 | a valid backup copy in case there is a power failure during |
| 321 | a "saveenv" operation. |
| 322 | |
| 323 | BE CAREFUL! Any changes to the flash layout, and some changes to the |
| 324 | source code will make it necessary to adapt <board>/u-boot.lds* |
| 325 | accordingly! |

| 344 | |

| 350 | |
| 351 | If offset is positive (the usual case), it is treated as relative to |
| 352 | the start of the MMC partition. If offset is negative, it is treated |
| 353 | as relative to the end of the MMC partition. This can be useful if |
| 354 | your board may be fitted with different MMC devices, which have |
| 355 | different sizes for the MMC partitions, and you always want the |
| 356 | environment placed at the very end of the partition, to leave the |
| 357 | maximum possible space before it, to store other data. |
| 358 | |
| 359 | These two values are in units of bytes, but must be aligned to an |

| 366 | valid backup copy in case the other copy is corrupted, e.g. due |
| 367 | to a power failure during a "saveenv" operation. |
| 368 | |
| 369 | This value may also be positive or negative; this is handled in the |
| 370 | same way as CONFIG_ENV_OFFSET. |

| 372 | This value is also in units of bytes, but must also be aligned to |

| 770 | Sometimes board require some initialization code that might |
| 771 | require once the actual init done, example saving board specific env, |
| 772 | boot-modes etc. which eventually done at late. |
| 773 | |
| 774 | So this config enable the late init code with the help of board_late_init |
| 775 | function which should defined on respective boards. |

| 816 | Some boards need to perform initialisation as soon as possible |
| 817 | after boot. With this option, U-Boot calls board_early_init_f() |
| 818 | after driver model is ready in the pre-relocation init sequence. |
| 819 | Note that the normal serial console is not yet set up, but the |
| 820 | debug UART will be available if enabled. |
