[LEDE-DEV] [PATCH 13/13] sunxi: Add A64 support with cortex53 subtarget

Hauke Mehrtens hauke at hauke-m.de
Thu Aug 3 14:37:59 PDT 2017 

This adds initial support for the A64 Allwinner SoC to LEDE.
It will be build in the new cortexa53 subtarget.

Currently it only supports the pine64 and the image is able to boot on
this SoC.
