Furthermore this SOC isn't supported by the mainline kernel either, so any plans to support it would involve a much more uphill battle than 'just' adding a new (mainline linux supported) target (which is already rather complex). But in this case you'd have to isolate the necessary SOC support patches from Huawei's GPL source (so they exist), hope that they're complete (not missing parts of of, not linking in binary-only objects) and legal to use (explicitly GPL2 (or compatible) licensed), before forward porting them to current kernels (and ideally submitting them to mainline linux first!). Once you've mastered that, you have to keep in mind that Huawei has its own wireless chipsets as well (admitted, I haven't looking what wireless solution this device is using), which doesn't have any mainline drivers either - so you'd be starting the same endeavour for those as well.
Chances for this to happen (unless you dedicate your own time and experience to it), minimal to non-existent - there are just better/ easier devices (and targets that are at least partially supported mainline) around.
