Subject: buildman: Support in-tree builds
X-Git-Tag: v2014.10-rc1~42
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=189a496825aefe7c8e9be80c0f2a4cf5923d4f55;p=u-boot

buildman: Support in-tree builds

At present buildman always builds out-of-tree, that is it uses a separate
output directory from the source directory. Normally this is what you want,
but it is important that in-tree builds work also. Some Makefile changes may
break this.

Add a -i option to tell buildman to use in-tree builds, so that it is easy
to test this feature.
