I will try to update this patchset when it's agreed how the limit on
transfer size is handled. Writing less data than was requested is
acceptable for spi-nor but might disrupt other drivers so perhaps some
preemptive mechanism with the SPI master saying how much data it can
transfer and the drivers looking at that value would be preferred.

Thanks

Michal
