commit 2dabff4a322d1dbf91155b30e05ceb6314679cdd Author: Hakim Giydan hgiydan@marvell.com Date: Tue Jul 5 14:51:07 2016 -0700
Add stub implementation of MVMAP2315 SOC
Most things still need to be filled in, but this will allow us to build boards which use this SOC
Nvidia Tegra210 SOC and Rochchip Rk3399 SOC has been used as templates to create this directory
