Here are some lightly tested improvements to the FSI driver that should
improve throughput.

They apply on top of the previous FSI series I sent.

Joel Stanley (7):
  fsi: aspeed: busy loop in the write case
  fsi: master: Change default divisor to 14
  fsi: aspeed: Enable relative addressing
  fsi: aspeed: Only select OPB0 once
  fsi: aspeed: Avoid copying read data twice
  fsi: aspeed: Pass fsi_master_aspeed insead of base
  fsi: aspeed: Special case repeated full word reads
