nit on style: I find easier to read the declarations when they fit in the
80-chars limit. There are 2 styles that meet this in spi_nor_ids[]:

        {
                "gd25q16", INFO(0xc84015, 0, 64 * 1024,  32,
                        SECT_4K | SPI_NOR_DUAL_READ | SPI_NOR_QUAD_READ |
                        SPI_NOR_HAS_LOCK | SPI_NOR_HAS_TB)
        },

and

        { "is25lp256",  INFO(0x9d6019, 0, 64 * 1024, 512,
                        SECT_4K | SPI_NOR_DUAL_READ) },

we should choose one and be consistent across flash_info declarations.

The info in patch is good, so:
