8G eMMC change to 16G eMMC

[wanglee]

          我们用iMX6Q芯片开发了一套板卡。能够正常使用。启动方式是eMMC，原来用的eMMC是东芝的的THGBM5G6A2JBAIR, 后来应客户的需求更换为SDIN5C2-16G，更换之后无法正常下载程序，会卡在如下图的地方，请问这个是焊接问题吗？iMX6Q支持16G的eMMC吗？如果支持，需要修改uboot？有没有相关的技术文档？

Hi wang

iMX6Q can support 16G eMMC, however there may be signal integrity

issues as for example below

In such case it is necessary to rebuild mfg tools firmware.
