Cannot boot enter the normal rich rootfs after burnning in rescue rootfs

[tonyho]

I followed the repo README.md guide, burned all the images, after rebooting into uboot, I can boot into the rescue kernel+rootfs with:

setenv loadaddr 0x22000000; ubi readvol ${loadaddr} rescue 0x800000; bootm ${loadaddr}#ssd202d-som2d01

But I cann't boot into the normal rich OS, if I do nothing after rebooting, the u-boot would gives the error:

If I use the following commands, it failed to find the rootfs and result in the VFS root mount failure panic:

setenv loadaddr 0x22000000; ubi readvol ${loadaddr} kernel 0x800000; bootm ${loadaddr}#ssd202d-som2d01

I guess this is the env partition is incorrect?
What is the the correct bootargs? And where can I set it(dts/uboot env)?
How can I boot into the normal rootfs?

It looks like we lost the rootfs info in the dts during mainlining work...

You need to tell the kernel to create a ubiblock and use that as root via the commandline.

Adding something like:

ubi.mtd=1 ubi.block=0,5 root=/dev/ubiblock0_5

@tonyho can you try replicate and reuse mine bootargs with ubifs (you will need to build it) from #7
