I agree the name SOCFPGA is confusing, since it is really a class of
device that is made by multiple manufacturers rather than a brand name,
but renaming that now would be equally confusing. If the Intel folks
could suggest a better name that describes all products in the platform
and is less ambiguous, we could rename it to that. I think ARCH_ALTERA
would make sense, but I don't know if that is a name that is getting
phased out. (We once renamed the Marvell Orion platform to ARCH_MVEBU,
but shortly afterwards, Marvell renamed their embedded business unit (EBU)
and the name has no longer made sense since).

Regardless of what name we end up with, I do think we should have the
same name for 32-bit and 64-bit and instead fix the edac driver to do
runtime detection based on the compatible string.
