[OpenWrt-Devel] [PATCH] [RFC] lantiq: disable a bunch of features not applicable to my box

Wed May 18 03:39:16 EDT 2016

- NAND/UBI support is completely irrelevant for my box, and for
  lantiq/Danube in general (IIRC). It appears to me that it would make
  sense to split it off from the xway target.
- My box has no USB port and no other sensible option to connect
  mass storage devices, so anything related to that makes no sense as
  well.
- Some stuff related to my boot configuration/partitioning. Some of it
  should be obsolete by now due to the recently added support for
  brnboot alternative image switching.
- foo & bar, i guess

I found no way to subtract features/kernel configs in device profiles,
hence this somewhat big hammer. This patch is obviously not meant for
upstreaming.
