Strange WARNING while do_kernel_configcheck()

[Markus Hubig <mhubig@imko.de>]

Hello @all,

I'm working on a bsp vor the taskit stamp9g20 cpu module.

I have a bbappend file for the linux-yocto_3.2 kernel which was ones working
but now (after updating the denzil branch from 7.0 to 7.0.1) I get a strange
error while building the kernel.

I managed to track the problem down to a warning at the do_kernel_configcheck
task ... 

The warning I get is:

| NOTE: validating kernel configuration
| WARNING: Can't find any BSP hardware or required configuration fragments.
| WARNING: Looked at 
|  <snip>/linux/meta/cfg/standard/default/arm-versatile-926ejs/hdw_frags.txt
| and
|  <snip>/linux/meta/cfg/standard/default/arm-versatile-926ejs/required_frags.txt
| in directory:
|  <snip>/linux/meta/cfg/standard/default/arm-versatile-926ejs

Which seems to be the wrong path to look, course there is no such path like

<snip>/linux/meta/cfg/standard/default/arm-versatile-926ejs

the whole stuff is in:

<snip>/linux/meta/cfg/standard/default/stamp9g20

maybe I made a mistake in my linux-yocto_3.2.bbappend file?

The code which is -generating- responsible for this warning is:

(from "meta/classes/kernel-yocto.bbclass")

| 1| python do_kernel_configcheck() {
| 2|     import bb, re, string, sys, commands
| 3| 
| 4|     bb.plain("NOTE: validating kernel configuration")
| 5| 
| 6|     pathprefix = "export PATH=%s:%s; " % (d.getVar('PATH', True), "${S}/scripts/util/")
| 7|     cmd = d.expand("cd ${B}/..; kconf_check -config- ${B} ${S} ${B} ${KBRANCH}")
| 8|     ret, result = commands.getstatusoutput("%s%s" % (pathprefix, cmd))
