Yeah, I think this is probably the way to go.

Yet it doesn't do what's needed for SPI flash (identify the chip type, when it can't probed); and for that application none of those methods are useful (and their slots are just wasted/confusing space). If anything, I believe that this header should move into linux/mtd/ and become a standard structure for platforms to communicate their requirements to flash drivers. Yeah, I think this is probably the way to go. Davids, any objections? I had similar thoughts when I first happened across that structure. But such a move wouldn't resolve $SUBJECT ... which is IMO best addressed by the obvious rename of the one to spi_flash_platform_data. - dave -- To unsubscribe from this list: send the line unsubscribe linux-embedded in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
