Max footprint for SPL in both Exynos 5250 and 5420 is limited to 14 KB. For Exynos5250 we need to keep it 14 KB because BL1 supports only fixed size SPL downloading. But in case of Exynos5420 we need not restrict it to 14 KB. And also, the SPL size for Exynos5420 is expected to increase with the upcoming patches and the patches under review right now.

Should this be 30? I think normally there is a 2KB space after it, so we use either 14KB or 30KB.
