From 426fcd2a351e4bf662fee9fa2cf2603a48223164 Mon Sep 17 00:00:00 2001 From: Philby John Date: Wed, 28 Oct 2009 19:09:12 +0100 Subject: ARM: 5774/1: Fix Realview ARM1176PB board reboot This is the fix for proper reboot of Realview ARM1176PB board when issuing the reboot command. Setting the eighth bit of control register SYS_RESETCTL to 1 to force a soft reset. arch_reset() is modified for realview machines to call machine specific reset function pointers.

This way there is no need to pass a "mem=" argument on the kernel command line.
