Define craw64 config, dts and Makefile for Cisco
SoCs known as Craw.
I'd like some more information about the platform, e.g. the target
market and maybe a link to the product information.
Our SoC is produced as an internal product. So SoC specifications aren't
widely available.

Here is an example of a Cisco product which uses this SoC,

I suspect that's not really what your looking for tho.
No, that's pretty much exactly what I was looking for. Just put this one
sentence and the link into the patch description and it will be fine.

The memory size is usually filled by the boot loader, just put an
empty node into the .dtsi file
Arnd, I must regretfully inform you that Cisco has a deep dark addiction to
bootloaders which, are, um, how do I say this diplomatically, um , brain dead.

You have some other comments below related to moving things into the bootloader,
and I can look into it, but bootloader inflexibility is wide spread inside
Cisco.
Ok, no worries. If the bootloader can do it right, you should do it, but
this part is not essential.
