I am not completly ready (I ported hopefully all drivers, hold it in
sync with mainline, but I need to test this again), so I think, it
would be better to wait for the next release cycle, but if now a
discussion is starting, if it is in principle ok, code can be found
at:
http://git.denx.de/?p=u-boot/u-boot-i2c.git;a=shortlog;h=refs/heads/multibus_v2
I hope to have this ready for next merge window, so a big test
phase can start!
Missing:
- overall cleanup
- completly delete CONFIG_HARD_I2C
- adapt README
- test, test, test
- "dynamic i2c bus"
Also this should be discussed:
- i2c devices must/should be ported to the new multibus functionality.
Here a short statistic for the actual state:
