From d12d3969d1d7501a1ebd8e642aa0f0a1098715de Mon Sep 17 00:00:00 2001 From: Vadim Kochan Date: Mon, 4 Mar 2019 01:23:40 +0200 Subject: [PATCH] package/sunxi-tools: fix build meminfo with musl musl does not provide inx/outx API for ARM arch, so use io memory access via pointers which is actually done this way in glibc/ulibc.
