Beside the quad-read/ddr-quad-read commands, all the commands needed by this driver is common. If we do not enable the quad-read, this driver can works with the fast-read mode. If we use a different NOR which uses different opcodes (different quad-read opcodes ?), i should add a small patch to fix it. I think i should follow Mark's advice to split out the quad-read code. thanks Huang Shijie -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
