2017-05-08	aspeed: Refactor AST2500 RAM Driver and Sysreset Driver	maxims@google.com
	This change switches all existing users of ast2500 Watchdog to Driver Model based Watchdog driver. To perform system reset Sysreset Driver uses first Watchdog device found via uclass_first_device call. Since the system is going to be reset anyway it does not make much difference which watchdog is used. Instead of using Watchdog to reset itself, SDRAM driver now uses Reset driver to do that. These were the only users of the old Watchdog API, so that API is removed. This all is done in one change to avoid having to maintain dual API for watchdog in between.

2017-01-28	aspeed: Add drivers common to all Aspeed SoCs	maxims@google.com
	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>
