We don't need them anymore, They are uniform on all Loongson64 systems
and have been fixed in DeviceTree.loongson3_platform_init is replaced
with DTS + driver.

Hmm, why it comes with my sign-off?
I assue it's my patch somewhere off the tree?
Thanks.

Hi, Jiaxun
Thank you very much for your reply.
Yes, it is like this.out of tree provides good ideas, and clean up
others by the way.
Thanks,

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
