[PATCH 0/4] spi: fsl-espi: eliminate linearization into intermediate buffer

[Heiner Kallweit <hkallweit1@xxxxxxxxx>]

Currently all transfers are copied into an intermediate buffer first,
and then written to the hardware from this buffer.

This patch set implements direct transfers between transfer buffers
and hardware, and it allows to get rid of the 64k intermediate buffer.

Heiner Kallweit (4):
  spi: fsl-espi: determine need for byte swap only once
  spi: fsl-espi: eliminate need for linearization when writing to hardware
  spi: fsl-espi: eliminate need for linearization when reading from hardware
  spi: fsl-espi: remove unused linearization code
