* use the smaller flash of the part mounted.

a2785bdf76 i2c-master: first hack working on f0 
read_i2c and write_i2c are not flexible enough, and terribly named.
they're going to have to go, but they're a nice start for some things.

cb945fa671 rcc-legal-ranges: run through a range of clocks 
blink fast/slow for each clock configuration tested, then finish by
blinking idly.

As of this commit, this test fails quickly on most L1 boards tested.
An update to libopencm3 is required to fix this.
