AM335x DRAM-related setting

Hi Sophia,

Where are you looking at these registers? The DDR is configured in the SPL in the s_init() function which can be found in <u-boot_dir>/board/ti/am335x/board.c:

	if (!strncmp("A335X_SK", header.name, HDR_NAME_LEN))
		config_ddr(303, MT41J128MJT125_IOCTRL_VALUE, &ddr3_data,
			   &ddr3_cmd_ctrl_data, &ddr3_emif_reg_data);
	else if  (!strncmp("A335BNLT", header.name, 8))
		config_ddr(400, MT41K256M16HA125E_IOCTRL_VALUE,
			   &ddr3_beagleblack_data,
			   &ddr3_beagleblack_cmd_ctrl_data,
			   &ddr3_beagleblack_emif_reg_data);
	else if (!strncmp("A33515BB", header.name, 8) &&
				strncmp("1.5", header.version, 3) <= 0)
		config_ddr(303, MT41J512M8RH125_IOCTRL_VALUE, &ddr3_evm_data,
			   &ddr3_evm_cmd_ctrl_data, &ddr3_evm_emif_reg_data);
	else
		config_ddr(266, MT47H128M16RT25E_IOCTRL_VALUE, &ddr2_data,
			   &ddr2_cmd_ctrl_data, &ddr2_emif_reg_data);

The ddr_data structures can be found in the same file. The DDR specific header file with all the definitions is <u-boot_dir>/arch/arm/include/asm/arch-am33xx/ddr_defs.h.

This configuration is done only in the SPL.

These files I refer to are from the PSP version 04.06.00.11.

Best regards,
Miroslav
