From be093beb608edf821b45fe00a8a080fb5c6ed4af Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 19 Mar 2009 16:20:24 +0000 Subject: [ARM] pass reboot command line to arch_reset() OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.
