[U-Boot] When to create a SoC directory for ARM

Dear Wolfgang,

I failed to find the guideline, here is my question. Pardon me if this
is a dump question as I am still new to ARM.

As David Feng post his patch set to add ARMv8 support, I am trying to
enable it for Freescale implementation. Let's name it as LS2 for this
discussion. I am thinking to reuse as much as possible for existing
codes, which include copying some header files from powerpc partially. I
noticed the SoC field in boards.cfg file and I am wondering how to use
it effectively. I want to put LS2 specific headers to
arch/arm/include/asm/arch-ls2. Do I need to copy all files from
arch/arm/include/asm/arch-armv8/? There aren't many but I see mmu.h is
included in start.S. I have been searching case like this in ARMv7 but
didn't see shared header file (maybe I missed it). Please advise.

Regards,

York
