From: Elad Nachman <enachman@xxxxxxxxxxx> Add support for Marvell ac5/x variant of the ARM sbsa global watchdog. This watchdog deviates from the standard driver by the following items: 1. Registers reside in secure register section. hence access is only possible via SMC calls to ATF. 2. There are couple more registers which reside in other register areas, which needs to be configured in order for the watchdog to properly generate reset through the SOC. The new Marvell compatibility string differentiates between the original sbsa mode of operation and the Marvell mode of operation.
