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. Signed-off-by: Jiaxun Yang <jiaxun.y...@flygoat.com> Signed-off-by: Qing Zhang <zhangq...@loongson.cn>
Acked-by: Jiaxun Yang <jiaxun.y...@flygoat.com> Hmm, why it comes with my sign-off? I assue it's my patch somewhere off the tree? Thanks. - Jiaxun
