Yes, once you pointed out I checked UM for Exynos4415, Exynos5250, 
Exynos5420 and Exynos5410 and all these manuals talks about SROM_BC{0-3} 
only. There is no offset such as SROM_BC{4,5} at least in these SoC 
manuals. Accordingly I modified size from 0x100 to 0x10. But looks like 
I missed to remove SROM_BC{{4,5} from exynos-srom.h. I checked only 
these registers are used in the driver, so as such it should not cause 
any issue in driver as of now, only we have some redundant entry in 
exynos-srom.h which can be removed if it's not applicable for any of 
Exynos SoC, after confirmation from Kukjin.
