-- CONFIG_ENV_IS_IN_EEPROM:
-
- Use this if you have an EEPROM or similar serial access
- device and a driver for it.
-
- - CONFIG_ENV_OFFSET:
- - CONFIG_ENV_SIZE:
-
- These two #defines specify the offset and size of the
- environment area within the total memory of your EEPROM.
-
- - CONFIG_SYS_I2C_EEPROM_ADDR:
- If defined, specified the chip address of the EEPROM device.
- The default address is zero.
-
- - CONFIG_SYS_I2C_EEPROM_BUS:
- If defined, specified the i2c bus of the EEPROM device.
-
- - CONFIG_SYS_EEPROM_PAGE_WRITE_BITS:
- If defined, the number of bits used to address bytes in a
- single page in the EEPROM device. A 64 byte page, for example
- would require six bits.
-
- - CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS:
- If defined, the number of milliseconds to delay between
- page writes. The default is zero milliseconds.
-
- - CONFIG_SYS_I2C_EEPROM_ADDR_LEN:
- The length in bytes of the EEPROM memory array address. Note
- that this is NOT the chip address length!
-
- - CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW:
- EEPROM chips that implement "address overflow" are ones
- like Catalyst 24WC04/08/16 which has 9/10/11 bits of
- address and the extra bits end up in the "chip address" bit
- slots. This makes a 24WC08 (1Kbyte) chip look like four 256
- byte chips.
-
- Note that we consider the length of the address field to
- still be one byte because the extra address bits are hidden
- in the chip address.
-
- - CONFIG_SYS_EEPROM_SIZE:
- The size in bytes of the EEPROM device.
-
- - CONFIG_ENV_EEPROM_IS_ON_I2C
- define this, if you have I2C and SPI activated, and your
- EEPROM, which holds the environment, is on the I2C bus.
-
- - CONFIG_I2C_ENV_EEPROM_BUS
- if you have an Environment on an EEPROM reached over
- I2C muxes, you can define here, how to reach this
- EEPROM. For example:
-
- #define CONFIG_I2C_ENV_EEPROM_BUS 1
-
- EEPROM which holds the environment, is reached over
- a pca9547 i2c mux with address 0x70, channel 3.
