From 40fef0490610686022f99b8e070df7ac761c11a0 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Sun, 2 Dec 2012 04:55:18 +0000 Subject: Introduce arch_phys_memset which works like memset but on physical memory The default implementation of this function is just memset, but other implementations will be needed when physical memory isn't accessible by U-Boot using normal addressing mechanisms.

This allows code shared by u-boot and the linux user-mode tools to link.
