我的任务
分享xilinx ZC7020开发板uboot启动提示Unimplemented compression type 23
自己制作了BOOT.BIN，设备树，以及ramdisk.image,
从SD卡启动之后，提示无效的映像。
根据最后的打印 Unimplemented compression type 23，我查了uramdisk.image.gz是gzip压缩的，
uImage是没有压缩的，都应该是可以识别的，也不至于会出现type为23，不懂这个23是因为什么导致的，求大神解答。。。

基本可以确定这应该是uboot的问题，我用开发板提供的uboot映像，设备树，ramdisk，uImage是可以启动成功的，只是换了uboot之后，就出现错误，我编译的uboot源代码是2016.07版本的。
加载地址应该没错的，都是一样的。
求大神帮忙看看，这是什么问题引起的。
