[U-Boot] SPL dcache

[Alex Kiernan]

I was looking at the differences between the TI U-Boot tree and the
upstream tree (as we've switched from one to the other) and I think
the only patch which I'm picking locally which isn't in upstream is
this one:

  [U-Boot,RFC,3/3] spl: Add support for enabling dcache

  https://patchwork.ozlabs.org/patch/699899/

As far as I can tell the other two patches in the series were applied,
just not this one and I can't see what the changes that were requested
were.

When we first had that change it did cause us some problems, but only
because we needed some settle time once the DDR clocks were
configured.

How do we get it back reconsidered for merging?
