I don't like this warning message.
The vast majority of people that see it will not be able to change their
firmware. So it will be forever cluttering up their boot logs.
Until they switch to use APPENDED_DTB. :-)
I am philosophically opposed to making the DTB an internal kernel
implementation detail.
For OCTEON boards, it is an ABI between the boot firmware and the
kernel, and is impractical to change.
One could argue that many years ago, when the decision was made (by me),
that we should have opted to carry in the kernel source code tree the
DTS files for all OCTEON boards ever made, but we did not do that. Due
to the non-reversibility of time, the decision is hard to reverse.
In the case of this MMC driver, the only real difference is that two
properties have legacy names that later had differing "official" names.
The overhead of carrying the legacy bindings is very low.
David.
