Do soft-power-on-reset in sys_reboot system call.
How to test this patch
Execute "sudo reboot" from command line. The system will start shutdown
sequence and finally reboot and U-Boot restarts.

Just a minor correction :)
The board name is KZM-A9-GT.

This patch ended up causing a new build warning in combination
with the io.h changes in Russell's tree.
I've just applied this patch on top, which is the same thing we
did to all the other open-coded mmio locations.

commit 28901c1fed11dfeab65f640878e85a9b61d311ed
Author: Arnd Bergmann <arnd@arndb.de>
Date: Sun Sep 23 22:41:21 2012 +0000
ARM: shmobile: add new __iomem annotation for new code
While we fixed up all instances that were already present in v3.6,
this one came in through new code.
Without this patch, building kzm9g_defconfig results in:
arch/arm/mach-shmobile/board-kzm9g.c: In function 'kzm9g_restart':
arch/arm/mach-shmobile/board-kzm9g.c:781:2: warning: passing argument 2 of '__raw_writel' makes pointer from integer without a cast [enabled by default]
