I've just tentatively added unbusy-i2c.patch to "series". This patch
makes u-boot poll the PMU (through I2C) only if there is a pending

The busy polling of I2C caused a number of problems, including

- a conflict with enabling fast charging upon USB detection
  (by now, this problem may already have been fixed through some
  other means)

- character loss on the serial console

- slow DFU:

This patch has been gathering dust for a while, but I think we've
now crossed the pain threshold for not having it, so I've just
added it.

Harald, if you're happy with it, I'll merge it into the patches it
