[U-Boot] [PATCH v2 16/41] i2c: add support for offset overflow in to address

2019-10-23 Thread Robert 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 fi
