Build for Netgear R7800

There very much appear to be two different hardware revisions...I have two R7800's that were Made in China that I have had running Kong's DD-WRT and just bought another R7800 recently that was Made in Thailand and was unable to install DD-WRT on it after trying all different methods (including many tries at tftp) . However, was eventually able to get stock OpenWRT installed on the newer Made in Thailand R7800...so here I am! Maybe something about what DD-WRT needs in the RAM that OpenWRT doesn't?

This should really belong in a more appropriate thread, Netgear R7800 exploration (IPQ8065, QCA9984) - For Developers, for the reasons that it isn't specific to hnyman's OpenWRT build.
