2019-12-23mpc85xx: ddr: Always start DDR RAM in Self Refresh modeJoakim Tjernlund
Some of t1042 boards fails DDR init with an Automatic calibration error every now and then. Investigations revealed that true Warm boots never failed. Warm boots has some extra steps performed, one being to start DDRC in Self Refresh and then clearing SR right after. Applying this SR method unconditionally made all our boards stable again, regardless of Cold/Warm boot.

2019-12-17i2c: add support for offset overflow in to addressRobert Beckett
Some devices (2 wire eeproms for example) use some bits from the chip address to represent the high bits of the offset instead of or as well as using multiple bytes for the offset, effectively stealing chip addresses on the bus. Add a chip offset mask that can be set for any i2c chip which gets filled with the offset overflow during offset setup.
