aspeed: Add drivers common to all Aspeed SoCs Add support for Watchdog Timer, which is compatible with AST2400 and AST2500 watchdogs. There is no uclass for Watchdog yet, so the driver does not follow the driver model. It also uses fixed clock, so no clock driver is needed. Add support for timer for Aspeed ast2400/ast2500 devices. The driver actually controls several devices, but because all devices share the same Control Register, it is somewhat difficult to completely decouple them. Since only one timer is needed at the moment, this should be OK. The timer uses fixed clock, so does not rely on a clock driver. Add sysreset driver, which uses watchdog timer to do resets and particular watchdog device to use is hardcoded (0) Reviewed-by: Simon Glass <sjg@chromium.org>

help
Select this to enable timer for Aspeed ast2400/ast2500 devices.
This is a simple sys timer driver, it is compatible with lib/time.c,
but does not support any interrupts. Even though SoC has 8 hardware
counters, they are all treated as a single device by this driver.
This is mostly because they all share several registers which
makes it difficult to completely separate them.

drivers: timer: Introduce ARC timer driver This commit introduces timer driver for ARC. ARC timers are configured via ARC AUX registers so we use special functions to access timer control registers. This driver allows utilization of either timer0 or timer1 depending on which one is available in real hardware. Essentially only existing timers should be mentioned in board's Device Tree description. Signed-off-by: Vlad Zakharov <vzakhar@synopsys.com> Reviewed-by: Simon Glass <sjg@chromium.org>
