From 32fd6901a6d8d19f94e4de6be4e4b552ab078620 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Tue, 8 Dec 2009 19:18:13 +0100 Subject: MIPS: Alchemy: get rid of common/reset.c Implement reset / poweroff in the board code instead. The peripheral reset code is gone too since YAMON which all in-tree boards use does the same work when it boots.
