From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Date: Fri, 06 Jun 2014 07:20:10 +0000 Subject: [PATCH v2 01/07] ARM: shmobile: Allow use of boot code for non-SMP case Message-Id: <20140606072010.14868.5474.sendpatchset@w520> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org From: Magnus Damm Allow build of platsmp.c and headsmp.S even though SMP is disabled in the kernel configuration. With this in place it is possible to share the reset vector setup code with power management code that needs to be built even though SMP is disabled.
