Change from v2: patch2: Modify Makefile for arch/arm/cpu/arm1176/s3c64xx/cpu_init.s in build error. It will generat redefine information for "mem_ctrl_asm_init" before the Modify. patch4: Modify the Sergei Shtylyov comments and change the SDRAM size variable for PHYS_SDRAM_SIZE_1.
Change from v3: Add new patch 3: I discuss with Amicalement, I find the mutiple-link issue: The first, the cpu_init.o have already been link for cmd_link_o_target atfer compile. But, The link script re-link the point file. So the link machine will generate multiple definition error information.
The second, Since the first 4kB of nand boot featue code move to nand_spl, So It is not necessary to force the cpu_init.o in non-nand boot.
Delete the cpu_init.o from u-boot-nand.lds is safe.
