[PATCH] arm64: rk3399: Add capacity-dmips-mhz attributes

[Marc Zyngier]

The RK3399 has the interesting property to be a so called "big-little"
system, where not all the CPUs are equal (the A53s are much weaker
than the A72s).

So far, we're not telling the OS that there is such a difference in
processing capacity, and Linux assumes that they are equal. Too bad.

Let's tell the OS about this by using the capacity-dmips-mhz
property. The values used here are those used on the Juno platform,
which is quite similar. This leads to the scheduler knowing that
it can pack more tasks on the A72s, and leads to a better interactive
experience.

Probably better to use the value from Juno r2 (485) which should more 
appropriately represent A53 vs. A72, rather than A53 vs. A57.

Oops.

Otherwise, though, I was on the verge of tackling this myself now that 
my 3399 board is building its own kernels - annoyance at the linking 
bottleneck steadfastly refusing to move off CPU0 (except occasionally to 
another little core) has been growing steadily :) With the nits fixed,

Indeed. Although I doubt that there is such a difference between A57
and A72, but I guess it won't really show.

Yeah, tell me about it. I still regularly build the kernel on my kevin,
and while the compilation time is reasonable for this kind of device
(and the storage media being an sdcard), the linking is just a pig.
Even on the A72.
