AM3352 NAND时序问题

 请问NAND FLASH的这些参数具体代表的是什么，和具体的NAND FLASH型号有关吗？

还是用默认的值就可以了？

nand-bus-width = <8>;
  gpmc,device-width = <1>;
  gpmc,sync-clk-ps = <0>;
  gpmc,cs-on-ns = <0>;
  gpmc,cs-rd-off-ns = <44>;
  gpmc,cs-wr-off-ns = <44>;
  gpmc,adv-on-ns = <6>;
  gpmc,adv-rd-off-ns = <34>;
  gpmc,adv-wr-off-ns = <44>;
  gpmc,we-on-ns = <0>;
  gpmc,we-off-ns = <40>;
  gpmc,oe-on-ns = <0>;
  gpmc,oe-off-ns = <54>;
  gpmc,access-ns = <64>;
  gpmc,rd-cycle-ns = <82>;
  gpmc,wr-cycle-ns = <82>;
  gpmc,wait-on-read = "true";
  gpmc,wait-on-write = "true";
  gpmc,bus-turnaround-ns = <0>;
  gpmc,cycle2cycle-delay-ns = <0>;
  gpmc,clk-activation-ns = <0>;
  gpmc,wait-monitoring-ns = <0>;
  gpmc,wr-access-ns = <40>;
  gpmc,wr-data-mux-bus-ns = <0>;

是根据demo板上镁光的NAND Flash来设定的，一般NAND FLASH的厂家的兼容性都是比较高的。
