From 7336c0036e22c42b961a88d751fcf64f9901c030 Mon Sep 17 00:00:00 2001 From: Daniel Verkamp Date: Tue, 21 Feb 2017 15:37:20 -0700 Subject: [PATCH] env/vtophys: combine DPDK physical address lookups vtophys_get_paddr() and vtophys_get_dpdk_paddr() are doing similar things; combine them into one function that works for all DPDK memory addresses. Part of the vtophys test is temporarily disabled until the next commit, which will register all DPDK memory at startup and stop lookiing up addresses at runtime.
