  • 456ecd08e   lib/crc8: Add crc start value ... Browse Code »

    To make the usage of this function more flexible, lets add the CRC start
    value as parameter to this function. This way it can be used by other
    functions requiring different start values than 0 as well.

    For non-zero CRC start values to work, I've reworked the function a bit.
    The new implementation is copied from the Linux version in
    drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero
    CRC stating values.

    I've double-checked that the results for zero starting values are
    identical to the results from the original version of this function.

    Add an implementation of the CRC8 algorithm. This is required by the TPM
    emulation, but is probably useful to U-Boot in general.
