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.

Subject: [PATCH] meminfo: Access to io memory via pointers
|
|
|
|
The main reason for this is to be able compile with musl library,
|
|
because there is no support of inx/outx functions for ARM platform.
