This patch implements a workaround to fix DDR3 memory issue. The code for workaround detects PGSR0 errors and then preps for and executes a software-controlled hard reset.In board_early_init, where logic has been added to identify whether or not the previous reset was a PORz. PLL initialization is skipped in the case of a software-controlled hard reset.
