eal/tile: add initial TILE-Gx support
This commit adds support for the TILE-Gx platform, as well as the TILE CPU architecture. This architecture port is fairly simple due to its reliance on generics for most arch stuff. Signed-off-by: Cyril Chemparathy <cchemparathy@ezchip.com> Signed-off-by: Zhigang Lu <zlu@ezchip.com>
