Hi Otavio, Jason, Fabio,

You're right, we need a decision. As far as I read, there is no
explanation why this change is required. As Fabio points out, dtb is
loaded before the kernel and this should avoid an overlap. It will be
very nice if Jason could better explain the issue, because I admit I
have not understood why it happens.

Maybe is DTB loaded after the kernel on Freescale's U-Boot ?

This is clearly a work-around for a bug in Freescale's kernel 3.10, as
we have no problems with other kernels. I booted mainline kernel
3.11/3.12 on a i.MX6 without this issue.

However, I could still merge the patch if we can at least have the
following answers:

- why is there the overlap if the kernel is loaded after DTB (Fabio's
question) ?
- add the explanation to the commit message (so V2 is required, this is
also a Wolfgang's comment).
- of course, the patch should generate a problem with other kernels. It
should not be, but a couple of tested-by will be nice.

As the patchset fixes the same issue, I would prefer if the patchset is
squashed into a single patch because it fixes a single issue and we can
have only one "extended" commit message with the whole explanation.

Best regards,
Stefano Babic
