I agree. It is a temporary solution, and it must be fixed soon. I see
the exynos_init() function and adapt the method to fix the problem in
Odroid XU3. But it did not work. Figuring out what is wrong, I found
that the 2 lines of code in the exynos_init() to reserve the last 1MB
does not affect the behavior of Odroid U3. Even after I commented out
the codes, it works well. Is it a effective solution to reserve the
memory? Is there anything else which I am missing?

I really appreciate for your comment. Thanks.

Best regards,
Hyungwon Hwang.
