相对于T2080-RDB，删除了NAND，扩大PCIe4的Mem Space到2GB（待试验），CPLD为4KB（LAW 4KB，AMASK 16KB，取小）

DDR
DDR主时钟修改，开发板133.33MHz，修改相关宏为66.66MHz，采用QCVS重新生成DDR初始化代码，
网络
网络配置，
不从i2c读取MAC
#define CONFIG_ID_EEPROM
在*\t2080\u-boot-qoriq-v2.0\include\configs\T208xRDB.hline652配置千兆网phy地址，
#define RGMII_PHY1_ADDR 0x07 /* RealTek RTL8211E */
#define RGMII_PHY2_ADDR 0x06
在*\u-boot-qoriq-v2.0\arch\powerpc\include\asm\config.hline102，可以看到CONFIG_PHYLIB在这里使能，所以menuconfig没有配置，
/* The FMAN driver uses the PHYLIB infrastructure */
#if defined(CONFIG_FMAN_ENET)
#define CONFIG_PHYLIB
#endif
万兆网走光纤，没有phy，看一下T2080 u-boot的网络初始化过程，用fixed phy驱动取代开发板上的phy。

Nor Flash
Nor Flash容量扩大，128MB增加到256MB，修改IFC宏，u-boot cp命令没有显示扇区地址，修改源代码添加这个打印。
NAND FLASH
没有Nand，注释T2080RDB.h相关宏，删除LAW，TLB，
*\board\freescale\t208xrdb\law.c
*\board\freescale\t208xrdb\tlb.c
CPLD/FPGA
更改配置头文件T2080RDB.h宏定义，
cpu_init_early_f arch\powerpc\cpu\mpc85xx\cpu_init_early.cinit_laws arch\powerpc\cpu\mpc8xxx\law.claw_table board\freescale\t208xrdb\law.cinit_tlbs arch\powerpc\cpu\mpc85xx\tlb.ctlb_table board\freescale\t208xrdb\tlb.c
cpu_init_f arch\powerpc\cpu\mpc85xx\cpu_init.cinit_early_memctl_regs drivers\misc\fsl_ifc.c
I2C
取消从EEPROM中读取MAC，取消VID电压控制，
万兆网
万兆网使用光口时，u-boot hwconfig环境变量需要配置，
hwconfig = fsl_ddr:ctlr_intlv=cacheline,bank_intlv=cs0_cs1;fsl_fm1_xaui_phy:xfi
uboot开机打印
经过上面的修改，uboot所有的开机打印警告消除，

Nor长度增大，去除nand，增加CPLD长度，
linux内核
menuconfig
打开jffs2，ext4，fuse，net phy，phy subsystem，NVMe，uio，rapidio配置，修改ramdisk，spi-nor配置，
USB
如果没有USB_CLKIN信号，写USB控制寄存器处理器会卡死，如果没有PHY时钟，使用USBx_CONTROL[PHY_CLK_VALID]位来检测USB PHY时钟，此处需要修改内核或者设备树，否则linux会hang住，
