This patch subtracts a part of clock init from spl and executes it after relocation. spl_clock_init executes in spl and system_clock_init executes after relocation in u-boot. This is done to gain some space by removing initially not necessary code.

Looks good - just one question below.
Changes since v1: - Rebased on ToT.

Shouldn't this only be included in the SPL build?
I tried to do that but, since other files are using some of the data defined in this file, we need it in u-boot as well. Please tell me if it's required I'll make another file for common data.
Are you saying that U-Boot proper is using the same data as SPL? I'm not sure, but I believe that we should not access SPL data from U-Boot, since they should be setting up separate things. Can you please be more specific about what is being shared?
Sorry, misunderstood the compiler errors. Actually data is not shared in spl and u-boot, but in the Makefile if I keep all the spl related files in "ifdef CONFIG_SPL_BUILD" lowlevel_init.s is not able to find tzpc, dmc and clock init function definitions. And if I keep lowlevel init as well in "ifdef CONFIG_SPL_BUILD", start.o is not able to find function definitions in lowlevel_init.s. In the next version of this patch-set, I'll fix it.
COBJS += dmc_common.o dmc_init_ddr3.o COBJS += tzpc_init.o COBJS += smdk5250_spl.o
ifndef CONFIG_SPL_BUILD +COBJS += clock_init.o COBJS += smdk5250.o endif
