695 Enable support for the I2C (Inter-Integrated Circuit) bus in SPL.
696 I2C works with a clock and data line which can be driven by a
697 one or more masters or slaves. It is a fairly complex bus but is
698 widely used as it only needs two lines for communication. Speeds of
699 400kbps are typical but up to 3.4Mbps is supported by some
700 hardware. I2C can be useful in SPL to configure power management
701 ICs (PMICs) before raising the CPU clock speed, for example.

1730 While loading from serial is slow it can be a useful backup when
1731 there is no other option. The Ymodem protocol provides a reliable
1732 means of transmitting U-Boot over a serial line for using in TPL,
1733 with a checksum to ensure correctness.
