Heiko Schocher d044954fe2 8xx, mgsuvd: rename board to a more generic name
renaming the "mgsuvd" board port into "km8xx", because
there come more similar boards from keymile.
Compiling the mgsuvd board with "make mgsuvd_config"
remains.

Heiko Schocher 19f0e93041 83xx, kmeter1: add I2C, dtt, eeprom support
This patch adds I2C support for the Keymile kmeter1 board.

accessing 4 temperature sensors, an eeprom with IVM data
and the booteeprom over a pca9547 mux.

Heiko Schocher c24853644d mgcoge, mgsuvd: add board specific I2C deblocking mechanism.
As documented in doc/I2C_Edge_Conditions, adding a
board specific deblocking mechanism via CFG_I2C_INIT_BOARD
for the mgcoge and mgsuvd board.

This code was originally written by Keymile in association
with Anatech and Atmel in 1998. The Code toggels the SCL
until the SCA line goes to HIGH (max. 16 times).
And after this, a start condition is sent.

This is another approach to deblock the I2C Bus. The
soft I2C driver actually sends 9 clocks with SDA High,
and then a stop at the end, to deblock the I2C Bus.

Maybe we should use the approach from Keymile as
the new standard?
