If it is only always enabled on x86 that means it is not on anything
else. So the option (at present) compiles the physmem.c file only on
x86 and sandbox. That is the purpose of the option.

I am not sure it would cause any harm to enable it for everything, but
I'd rather just do the conversion. It's fine to look at things in a
new light when we convert options, but that sort of change can easily
be done later. The CONFIG conversion has been going on for 6 years,
partly because people don't like touching old things, partly because
people want them cleaned up...

Simon

Applied to u-boot-dm/next, thanks!
