Subject: backports: add make help and defconfig-help targets
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=75ff03ec2a9fbd48e4191ac82d6ffbf78e8f0a90;p=openwrt%2Fstaging%2Fblogic.git

backports: add make help and defconfig-help targets

Throw users a bone by helping them compile specific target
drivers. Hauke did some good work in providing tons of
defconfigs, provide a command to let users query these
easily with 'make defconfig-help'. Also provide a more
generic 'make help' target.

Screenshot of make defconfig-help:

mcgrof@frijol ~/backports-20130618 $ make defconfig-help
Driver or subsystem configuration targets:
  defconfig-alx
  defconfig-ar5523
  defconfig-ath5k
  defconfig-ath6kl
  defconfig-ath9k
  defconfig-ath10k
  defconfig-b43
  defconfig-b43legacy
  defconfig-brcmfmac
  defconfig-brcmsmac
  defconfig-carl9170
  defconfig-drm
  defconfig-ieee802154
  defconfig-iwlwifi
  defconfig-media
  defconfig-nfc
  defconfig-regulator
  defconfig-rtlwifi
  defconfig-wifi
  defconfig-wil6210

Running 'make help' will provide the above and in addition to that
something similar to what the Linux kernel provides with the
list of supported targets backports provides.
