Would this also apply to all platforms in the LS family, or just LS1021 family?  If there will be a different kernel for the old Mindspeed parts that are being rebranded to LS1 (e.g.LS1024), it might be more appropriate to name this something more specific.
[Luo Zhenhua-B19537] Currently only ls1021aqds and ls1021atwr are supported, the same recipe will apply to all supported LS1 targets. I will update the name to linux-ls1 to differentiate with LS2. .
