Yes for LSDK, tool-chain being used is GCC 5.4.1. Following is analysis with LSDK too-chain:

SPL size for Secure boot image without dcache code:	83K
Available max OCRAM memory size for SPL image:	84K
SPL size for Secure boot image with dcache code:	85K

So for LSDK we have remove dcache code for Secure boot to work with current SPL size reduction.
