New and updated SoC support. Also included are some cleanups where the
platform maintainers hadn't separated cleanups from new developent in
separate branches.
Some of the larger things worth pointing out:
- A large set of changes from Alexandre Belloni and Nicolas Ferre
preparing at91 platforms for multiplatform and cleaning up quite a
bit in the process.
- Removal of CSR's "Marco" SoC platform that never made it out to the
market. We love seeing these since it means the vendor published
support before product was out, which is exactly what we want!
New platforms this release are:
- Conexant Digicolor (CX92755 SoC)
- Hisilicon HiP01 SoC
- CSR/sirf Atlas7 SoC
- ST STiH418 SoC
- Common code changes for Nvidia Tegra132 (64-bit SoC)
We're seeing more and more platforms having a harder time labelling
changes as cleanups vs new development -- which is a good sign that
we've come quite far on the cleanup effort. So over time we might start
combining the cleanup and new-development branches more.
