looping here
If I revert that patch, there are still lots of Bus speed messages, but
finally would enter into system.

This reverts commit f90142683f04bcb0729bf0df67a5e29562b725b9.
It is reported that making RK3288 can't boot from eMMC/MMC.
Could you explain in more detail?
As you mentioned, this patch is making that RK3288 can't boot..then
why?
Good way should be that finds the main reason and fixes it.
Not just revert.
To Shawn,
Could you check this? If you have rk3288..
If it's not working fine, it needs to revert this patch until finding
the problem.
Hrmm.....as that patchset was tested based on rk3288 and rk3368, so I
need to know which board Randy are using now and could you share some
Sorry, XZY has asked me about this in the morning and I answer him
that I would give a feedback at home, so I didn't notice this mail.
The board is Firefly reload. but the reporter told me that Firefly
release also have the same problem.
log?
I will have a look at it.

Jaehoon Chung
