Kernel Boot Failing on Zynq in U-Boot
让设备树决定emmc的设备号
添加如下代码，
struct mmc_host *mmc_alloc_host(int extra, struct device *dev)
{
int err;
struct mmc_host *host;
int aliasesid;/*add by zhuce*/
...
aliasesid = of_alias_get_id(dev->of_node, "mmc");
if (aliasesid>= 0) {
host->index = aliasesid;
}
...
}
此时mmc的设备号变了，但是块设备的标号还是没变，先扫描到的为mmcblk0，所以只要在设备树里把要先发现的mmc放到前面就可以保证它的mmc的设备号和块设备号都是0。
zu emmc降频到HS模式
发现ftp上传大文件到emmc内核会卡死，尝试降频到HS模式，在linux下只需要修改设备树，uboot和fsbl下降频比较复杂，参考AR69368。
&sdhci0 {
no-1-8-v;
};
降频后还是卡死，但是有改善，可以上传400MB文件，上传1GB文件还是卡死。

ftp截图，
这个问题在zynq平台没有出现过。。。
不识别SD卡
SD卡识别不到都是因为更换了hdf没有更新fsbl的原因，但看了fsbl的源代码，没有相关代码，所以应该是hw project的系统初始化中的相关代码，更改后识别到ZC706 SD卡，
