why you want to disable this CPU.
These limitations are meant to expose to end-user only features that make sense
and are appropriately tested. People like you can easily comment out theses
lines and do whatever experimentation they like.
About defined(CONFIG_USER_ONLY), it is just because a reasonable testing was
not provided for system mode. It is not enough to add a code, and then enable
system mode. A reasonable ("acceptance") testing should be done, and made
available to others. I know, we do not have strict acceptance rules. But I
would say a system image, kernel, and command line + plus some relatively mild
testing of system mode should suffice. It would be nice to formalize that.
About !defined(TARGET_MIPS64), this is because O32 is the only supported
user-mode ABI for this CPU.
One missing part is documentation update - unfortunately often forgotten.
