Question about cache flush in arm-tf #708

Hi all,

I am a novice of arm-tf. Currently I am trying to flush a specific region. I know the Linux kernel provide several useful functions, such as "__flush_cache_user_range()", but I guess such functions are used in EL1/0, not EL3.

Then, when I am finding a function or instruction to flush cache, I can only find "flush_dcache_range()" for Dcache, but nothing for Icache( Icache is related with mmu, but this may not be what I want).

So, I want to find an instruction (or a function) to flush Dcache+Icache in ARM-TF, can someone help me?

Thanks,
irakatz
