海思编解码芯片添加64M nor flash

uboot和内核都必须修改。

struct spi_info hisfc350_spi_info_table[] ；

在结构体里面添加自己的flash节点，我这里用的是MX66LS51235E

{
         "MX66L(S512)35(E/F)", //chip name
         {0xC2,0x20, 0x1A}, ///chip id nor flash has itself ID
         ,  //ID len
         _64M, //flash size
         _64K, //falsh sectors size
         , //clock
         {
            &READ_STD(,  INFINITE, /**/), //standard read clock, in datesheet
            &READ_FAST(, INFINITE, ),///fast read clock, in datesheet
            &READ_DUAL(, INFINITE, ),///dual read clock, in datesheet
            &READ_DUAL_ADDR(, INFINITE, ),///dual read addr clock, in datesheet
#ifndef CONFIG_CLOSE_SPI_8PIN_4IO
            &READ_QUAD_ADDR(, INFINITE, ),///qual read addr clock, in datesheet
#endif

        },
        {
            &WRITE_STD(, , ),

        },

        {
            &ERASE_SECTOR_64K(, _64K, ),

        },
        &spi_driver_mx66lS512, // 驱动函数，寻找类似的芯片修改即可！，如果没有要看detasheet 编写相应的驱动程序
}
