| 90 | Define this if you have a flash device which you want to use for the |
| 91 | environment. |
| 92 | |
| 93 | a) The environment occupies one whole flash sector, which is |
| 94 | "embedded" in the text segment with the U-Boot code. This |
| 95 | happens usually with "bottom boot sector" or "top boot |
| 96 | sector" type flash chips, which have several smaller |
| 97 | sectors at the start or the end. For instance, such a |
| 98 | layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In |
| 99 | such a case you would place the environment in one of the |
| 100 | 4 kB sectors - with U-Boot code before and after it. With |
| 101 | "top boot sector" type flash chips, you would put the |
| 102 | environment in one of the last sectors, leaving a gap |
| 103 | between U-Boot and the environment. |
| 104 | |
| 105 | CONFIG_ENV_OFFSET: |
| 106 | |
| 107 | Offset of environment data (variable area) to the |
| 108 | beginning of flash memory; for instance, with bottom boot |
| 109 | type flash chips the second sector can be used: the offset |
| 110 | for this sector is given here. |
| 111 | |
| 112 | CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE. |
| 113 | |
| 114 | CONFIG_ENV_ADDR: |
| 115 | |
| 116 | This is just another way to specify the start address of |
| 117 | the flash sector containing the environment (instead of |
| 118 | CONFIG_ENV_OFFSET). |
| 119 | |
| 120 | CONFIG_ENV_SECT_SIZE: |
| 121 | |
| 122 | Size of the sector containing the environment. |
| 123 | |
| 124 | |
| 125 | b) Sometimes flash chips have few, equal sized, BIG sectors. |
| 126 | In such a case you don't want to spend a whole sector for |
| 127 | the environment. |
| 128 | |
| 129 | CONFIG_ENV_SIZE: |
| 130 | |
| 131 | If you use this in combination with CONFIG_ENV_IS_IN_FLASH |
| 132 | and CONFIG_ENV_SECT_SIZE, you can specify to use only a part |
| 133 | of this flash sector for the environment. This saves |
| 134 | memory for the RAM copy of the environment. |
| 135 | |
| 136 | It may also save flash memory if you decide to use this |
| 137 | when your environment is "embedded" within U-Boot code, |
| 138 | since then the remainder of the flash sector could be used |
| 139 | for U-Boot code. It should be pointed out that this is |
| 140 | STRONGLY DISCOURAGED from a robustness point of view: |
| 141 | updating the environment in flash makes it always |
| 142 | necessary to erase the WHOLE sector. If something goes |
| 143 | wrong before the contents has been restored from a copy in |
| 144 | RAM, your target system will be dead. |
| 145 | |
| 146 | CONFIG_ENV_ADDR_REDUND |
Simon Glass | 547cb40 | 2017-08-03 12:21:49 -0600 | [diff] [blame] | 147 | |

| 152 | |
| 153 | BE CAREFUL! Any changes to the flash layout, and some changes to the |
| 154 | source code will make it necessary to adapt <board>/u-boot.lds* |
| 155 | accordingly! |

| 178 | |
| 179 | CONFIG_ENV_OFFSET: |

| 182 | These two #defines specify the offset and size of the environment |
| 183 | area within the specified MMC device. |
| 184 | |
| 185 | If offset is positive (the usual case), it is treated as relative to |
| 186 | the start of the MMC partition. If offset is negative, it is treated |
| 187 | as relative to the end of the MMC partition. This can be useful if |
| 188 | your board may be fitted with different MMC devices, which have |
| 189 | different sizes for the MMC partitions, and you always want the |
| 190 | environment placed at the very end of the partition, to leave the |
| 191 | maximum possible space before it, to store other data. |

| 200 | valid backup copy in case the other copy is corrupted, e.g. due |
| 201 | to a power failure during a "saveenv" operation. |
| 202 | |
| 203 | This value may also be positive or negative; this is handled in the |
| 204 | same way as CONFIG_ENV_OFFSET. |

| 235 | block size. Specifying a range with more erase blocks than |
| 236 | are needed to hold CONFIG_ENV_SIZE allows bad blocks within |
