This broadcom based wireless, there is basically zero support for the chipset in mainline Linux.
And, even if you wanted to run it wired only, there is no HiSilicon support in Openwrt and mainline linux doesn't support this SOC - so anyone wanting add support would be writing the platform support from scratch, trying to port Linux to a device that only supported kernel 2.6.
Out of sheer, unhealthy curiosity, I tried googling around and....there's literally zero documentation available for that SoC (or I don't know where to look?). One can probably only get the documentation from Huawei, if one is a big hardware-manufacturer and it'll all be behind NDAs and whatnot.
I certainly wouldn't have the skills to add support for a completely new CPU from scratch to begin with, let alone with zero documentation. It being a decade old and only used in Huawei-hardware, ie. not a particularly popular SoC, really doesn't make it any more appealing.
Nah, at this point I'd rather just desolder any useable parts from the device and throw the rest away.
I don't understand the intent of your comment. I wasn't asking OP to send me the hardware, I just mentioned what I'd do with such a device, if I had one -- I have a habit of desoldering flash, RAM, buck/boost converters, I2C EEPROM etc. out of broken/old devices before I send the rest to be recycled.
Adding support for a device, like e.g. a router, is a completely different thing than adding support for an SoC from scratch, with zero documentation or anything. You can't just throw a couple of files together, you need to know how all the peripherals are driven at register-level, any possible memory-layout related quirks and so on and so forth -- it's a ton of work even when you have documentation.
Adding support for a new device of a well-supported target takes you a long and rainy weekend, if you know what you're doing.
Adding support for a new target will take you months or years, even if source were available - without that, chances are very slim. Take a look at ipq807x, for which source has been available since day one, now, two-and-a-half years later, merging into OpenWrt slowly becomes realistic.
