If the user is sure that the reserved 0x00 - 0x02 and 0x77 - 0x7f ranges
are not needed by its devices, then the "-a" option can be passed for
allowing all theorical addresses to be used. It is then possible to
access devices in this address range.

This tool allows to construct and concat multiple I2C messages into one
single transfer. Its aim is to test I2C master controllers, and so there
is no SMBus fallback.
I've been missing such a tool a number of times now, so I finally got
around to writing it myself. As with all I2C tools, it can be dangerous,
but it can also be very useful when developing.
It has been tested with various Renesas I2C IP cores as well as Tegra,
i.MX and AT91.
