    Add support for read/write of ONIE "Tlvinfo" EEPROM data format. TLV
    stands for Type-Length-Value. The data format is described here:

    https://opencomputeproject.github.io/onie/design-spec/hw_requirements.html#board-eeprom-information-format

    Based on U-Boot patch from the Open Compute project:

    https://github.com/opencomputeproject/onie/blob/ec87e872d46b9805565d2c6124b2f701ef1c07b1/patches/u-boot/common/feature-sys-eeprom-tlv-common.patch

    Keep only I2C EEPROM support. Use the generic eeprom driver. Fix
    checkpatch issues.

    Add support for multiple EEPROM TLV stores on the same system. This is
    useful in case of SOM and carrier that both provide ID and hardware
    configuration information.

    Add option to enable for SPL. This allows selection of RAM configuration
    based on EEPROM stored board identification.
