I see no feedback from your side on this patch. I think you should go through
the marvell tree:
- the spi_claim/release_bus function are already implemented in the SPI
subsystem
- this patch touches only a kirkwood driver
- there is no spi u-boot tree from what I see
Please keep me up to date about the status of this patch

Valentin
