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
		 3,//ID len
		 _64M,//flash size
		 _64K,//falsh sectors size
		 4,//clock
		 {
			&READ_STD(0,INFINITE,40/*50*/),//standard read clock,in datesheet 
			&READ_FAST(1,104),///fast read clock,in datesheet 
			&READ_DUAL(2,///dual read clock,in datesheet 
			&READ_DUAL_ADDR(1,84),///dual read addr clock,in datesheet 
#ifndef CONFIG_CLOSE_SPI_8PIN_4IO
			&READ_QUAD_ADDR(3,70),///qual read addr clock,in datesheet 
#endif
			0
		},{
			&WRITE_STD(0,256,75),0
		},{
			&ERASE_SECTOR_64K(0,_64K,80),&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
}
