【DLT-RK3288试用】13,修改uboot

u-boot 以前出错的地方是 rockchip 的板级启动代码，去掉了，只改了一行代码搞定，uboot 正常启动：
去掉了代码是  u-boot/board/rockchip/rk32xx/rk32xx.c 文件中，倒数几行有一个 board_fbt_preboot() 函数，去掉就可以了：

rockchip 原本的启动文件启动方式是专有的，代码没有合入后来的 uboot 主线。不熟悉怎么启动的，也没看。之前一直报错，有两个解决方法：1，就是看看它需要什么什么文件，准备他需要的文件。这个方法就是照着按照 rockchip 的方式启动。
2，就是看看源码，把他的驱动方式取消了，使用常规的方法，本文就是准备替换成主线的启动方式。
没事自己玩，瞎折腾，弄哪是哪吧
