ELDK 4.2/kilauea/3.5+ kernel broken

Hi,

The attached patch from here:
http://thread.gmane.org/gmane.linux.ports.ppc.embedded/49637/focus=49903
works as far as I can say from > 3.2 kernels until 3.4.12 and applies happily even on 3.5.

Unfortunately the last kernel version which boots on a kilauea with ELDK 4.2 is v3.4.12 (with the attached patch applied). BTW v3.6 does not need the patch anymore, but exposes the same behavior as described below.

A default config with PPC_EARLY_DEBUG_40x makes the board stuck instead of rebooting, which happens from v3.5 onwards (with patch applied):

Subject: [PATCH] powerpc/boot: Only build board support files when required.

Currently we build all board files regardless of the final zImage target. This is sub-optimal (in terms on compilation) and leads to problems in one platform needlessly causing failures for other platforms.

Use the Kconfig variables to selectively construct this board files to build.
