I personally find having the defaults for various popular platforms
readily available in menuconfig to be a lot easier than having to dig
some documentation to find the appropriate addresses.

I.e, the current way is perfect. It's just that there is no need to
show the physical/virtual addresses if an existing well-known platform
is selected, especially as it causes weird behavior due to how kconfig
works. Which Boris patch is solving.

Best regards,

Thomas
