| |
As the mach-netx and mach-8695 platforms are being removed now, I wonder whether we should do the same with w90x00: Here is what I found after looking at the git history and external material for it.
- The supported chips (nuc910/950/960) are no longer marketed by the manufacturer
- Newer chips from the same family (nuc97x, nuc980, n329x) that are still marketed have Linux BSPs but those were never submitted for upstream inclusion.
- Wan ZongShun is listed as maintainer, but the last patch he wrote was in 2011.
- All patches to w90x900 platform specific files afterwards are cleanups that were apparently done without access to test hardware.
- The http://www.mcuos.com/ website listed in the MAINTAINERS file is no longer reachable.
We do support the newer NPCM platform from Nuvoton. I don't think there are any shared drivers between the two, but I've added its maintainers to Cc anyway, in case they still (plan to) use one of those drivers.
If we decide that it's time to let go, I'll would the patches below.
