uboot 2020.1 启动 vxworks7 sr620

uboot引导vxworks7

1. Creating a Uniprocessor VxWorks Source Build
2. Creating a CPU Based VxWorks Source Build
3. Creating a VxWorks Kernel Image With Embedded DTB
   5.内核配置截图
   6.修改设备树的串口时钟，使用MZ702P板子，配置的串口时钟为100M
   默认BSP的时钟频率为50M
   
4. build project
   build target
5. u-boot配置环境变量
   => setenv fdt_high 0xffffffff
   => setenv ipaddr 192.168.0.202
   => setenv netmask 255.255.255.0
   => setenv serverip 192.168.0.10
   => setenv bootargs ‘gem(0,0)host:vxWorks h=192.168.0.202 e=192.168.0.10:ffffff00 u=target pw=vxTarget f=0x00’
   => saveenv
6. uboot引导启动
   tftpboot 0x5000000 uVxWorks
   bootm 0x5000000
   
   目前使用独立的DTB文件还不能正常启动。参考BSP目录下的readme文件就是使用独立的DTB文件，不能正常启动。
