[U-Boot,RFC,00/22] Add support for Cavium Octeon-TX CN80XX/CN81XX

The Cavium Octeon-TX 64-bit ARM based SoCs include the CN80XX and CN81XX.
These SoC's have peripheral drivers based on PCI ECAM.

This series has been tested on the the following Gateworks SBC's:
 - GW6100 - CN8021 dual A53 800MHz
 - GW6104 - CN8031 quad A53 1500MHz
 - GW6300 - CN8020 dual A53 800MHz
 - GW6304 - CN8030 quad A53 1500MHz

These patches all came originally from Cavium's SDK based on a 2017 version
of U-Boot and have been refactored a bit to strip out things that didn't make
sense that I saw in the original code.

These patches apply on top of U-Boot 2018.11 and if needed I can do minor
cleanup and rebase on top of master but I can't be the maintainer.

I'm also looking for comments on the PCI related patches as I am by far not
a PCI expert and am not sure what I've done here is correct for this SoC and
the others some of the changes would affect.

I'm looking for a maintainer for this - I only have boards with the above SoC's
and can't test anything else. I also don't have the resources to be a
maintainer of this arch - I'm looking at you Cavium/Marvell as your SDK's use
old forks of U-Boot with a slew of patches and there is no reason to not
mainline this code. I've added all the cavium/marvell contacts I could find
from previous threads about OcteonTX support in U-Boot.

The way I'm using this on the above boards is to build u-boot-nodtb.bin
and package it into a FIP image that the ATF loads. I can document this process
if needed.

You can find this series on github [1]

Best Regards,

Tim
