The patch to support DDR3L in LS1043A

[#1]

The attached patch is to support DDR3L in LS1043A.

The SDK version is Linux-LS1043A-SDK-V0.5-SOURCE-20151223-yocto.iso. Not SDK2.0.

The DDR3L part number is two Winbond W632GU6KB(16M x 8 banks x 16 bits DDR3L SDRAM).

It looks like that part of your patch code is not needed. NXP SDK 2.0 include/configs/ls1043ardb.h file contains the following:

#include "ls1043a_common.h"

This file contains the following:

#ifndef CONFIG_SYS_FSL_DDR4

#define CONFIG_SYS_FSL_DDR3                              /* Use DDR3 memory */

#endif

#define CONFIG_VERY_BIG_RAM

#define CONFIG_SYS_DDR_SDRAM_BASE          0x80000000

#define CONFIG_SYS_FSL_DDR_SDRAM_BASE_PHY      0

#define CONFIG_SYS_SDRAM_BASE                      CONFIG_SYS_DDR_SDRAM_BASE

#define CONFIG_SYS_DDR_BLOCK2_BASE 0x880000000ULL

Have a great day,
Pavel Chubakov

You still need to add DDR3 raw timing parameters and DDR3 ODT definition in u-boot.

SDK2.0 doesn't has these code.
