2014-09-17ARM: keystone: ddr3: workaround for ddr3a/3b memory issueMurali Karicheri
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.

2014-07-25keystone: ddr3: add ddr3.h to hold ddr3 APIKhoronzhuk, Ivan
It's convinient to hold ddr3 function definitions in separate file such as ddr3.h. So move this from hardware.h to ddr3.h. Acked-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
