> SPI-NOR framework currently supports-
> - (1-1-1, 1-1-2, 1-1-4) read protocols
> - read latency(dummy bytes) are hardcoded with the assumption

> - No support of mode bits.

>
> This patch set add support of 1-2-2, 1-4-4 read protocols.
> It ports Linux commits "mtd: spi-nor: add a stateless method to support
> memory size above 128Mib" and "mtd: spi-nor: parse Serial Flash
> Discoverable Parameters (SFDP) tables". It enables 4byte address opcode
> and run time flash parameters discovery including dummy cycle and mode
> cycle.

May I rebase this patch-set on top of your " [PATCH v10 00/27] dm: Generic MTD Subsystem,with SPI-NOR interface" patch-set.
u-boot-spi.git repo will be good place for the rebase. It will help in merging my patch-set.
