If we want to allow users to disable distro,
and do not want ARCH_SUNXI appear in a generic config entry,
perhaps we can do like this.
config ARCH_SUNXI
bool
select ARCH_SUPPORTS_DISTRO
config DISTRO_DEFAULTS
bool "Select defaults suitable for booting general purpose
Linux distributions"
default y if ARCH_SUPPORTS_DISTRO
Currently it is just fine,
but we might want to do something in the future
when we have more platforms to migrate to this way...
config DISTRO_DEFAULTS
bool "Select defaults suitable for booting general purpose Linux
distributions"
default y if (ARCH_SUNXI || ARCH_TEGRA || ARCH_HISI || ARCH_ZYNQMP ... )

> + select CMD_MII
> + select CMD_PING

Do you mean all of these commands are mandatory for disto?
Or just recommended?
