From b851504dcf5e147c9efb1c7b6a4d22c1a1a87cd7 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Tue, 20 Jan 2015 13:01:29 +0000 Subject: kernel/image/depmodwrapper: Fixups for depmod With the rpm package backend enabled, running: bitbake bitbake virtual/kernel -c clean bitbake -c rootfs -f results in an image with incorrect kernel module dependency information. The problem is that the System.map and kernel-abiversion files are needed for depmod and after the recent kernel changes, these are no longer in sstate. Its reasonable to require the kernel to unpack/build if you're about to build a module against it. It is not reasonable to require this just to build a rootfs. Therefore stash the needed files specifically for depmod. Also fix some STAGING_KERNEL_DIR references which were incorrect, found whilst sorting through his change.
