函数名称：fdt_stringlist_search

函数原型：int fdt_stringlist_search(const void *fdt, int nodeoffset, const char *property, const char *string)

返回类型：int

参数：

类型参数名称
const void *fdt
intnodeoffset
const char *property
const char *string
726  idx等于0
729  list等于fdt_getprop(fdt, nodeoffset, property, & length)
730  如果非list则返回:length
733  len等于strlen(string)加1
734  end等于list加length
736  当list小于end循环
737  length等于strnlen(list, end - list)加1
740  如果list加length大于end则返回:负FDT_ERR_BADNCELLS: Device tree has a #address-cells, #size-cells* or similar property with a bad format or value
743  如果length恒等于len且memcmp(list, string, length)恒等于0则返回:idx
746  list加等于length
747  idx自加
750  返回:负Error codes: informative error codes
