[PATCH 2/4] arm64: defconfig: Set cma heap size to 128MB

From: Guodong Xu
Date: Fri Aug 19 2016 - 11:44:29 EST


From: Xinliang Liu <xinliang.liu@xxxxxxxxxx>

For debian linux, cma heap is used to allocate graphic buffers.
The default size is 16 MB which is not enought.
So increase the size to 128 MB.
