Thanks for confirming.

I guess we need to add something like
#if !CONFIG_CC_IS_GCC || CONFIG_LD_VERSION >= 23600
around the entry-armv.S changes and maybe select 
HAVE_LD_DEAD_CODE_DATA_ELIMINATION in arch/arm/Kconfig only if the same 
conditions are met ??

I had screwed up the CC list when I last replied and LAK list got 
changed to lak-join email id by mistake. Fixing that in this reply as well.

Thanks,
Warm Regards,
