From: Nolan Leake <nolan@sigbus.net>

This is just enough to make reboot and poweroff work. Works for

linux, u-boot, and the arm trusted firmware. Not tested, but should

work for plan9, and bare-metal/hobby OSes, since they seem to generally

do what linux does for reset.

The watchdog timer functionality is not yet implemented.

From: Joe Komlodi <joe.komlodi@xilinx.com>

If the CPU is running in default NaN mode (FPCR.DN == 1) and we execute

FRSQRTE, FRECPE, or FRECPX with a signaling NaN, parts_silence_nan_frac() will

assert due to fpst->default_nan_mode being set.

To avoid this, we check to see what NaN mode we're running in before we call

floatxx_silence_nan().

From: Maxim Uvarov <maxim.uvarov@linaro.org>

qemu has 2 type of functions: shutdown and reboot. Shutdown

function has to be used for machine shutdown. Otherwise we cause

a reset with a bogus "cause" value, when we intended a shutdown.
