[U-Boot] [RFC PATCH 7/7] Switch over to Kbuild
Simon Glass
sjg at chromium.org
Mon May 13 04:25:40 CEST 2013
This is just for testing, to show what failures exist when moving to the
Kbuild-based build system. Unfortunately due to broken out-of-tree
building, buildman just gives an error on this commit.

+# unavoidable when linking the built-in.o targets which finally

+# is now up to date.
#
+# The only cases where we need to modify files which have global
+# effects are thus separated out and done before the recursive
+# descending is started. They are now explicitly listed as the

-# to the target architecture. (See arch/* for the possibilities).
-# ARCH can be set during invocation of make:

-# Another way is to have ARCH set in the environment.
-# The default ARCH is the host where make is executed.
-

-# Alternatively CROSS_COMPILE can be set in the environment.
-# A third alternative is to store a setting in .config so that plain
-# "make" in the configured kernel build directory always uses that.
