[yocto] Errors while creating a new PowerPC 405e tune file

[Elvis Dowson]

Hi,
     I have defined a tune-ppc405e.inc ( suffixed with an 'e' to signify that it has a hardware floating point unit attached), as follows:

DEFAULTTUNE ?= "ppc405e"

require conf/machine/include/powerpc/arch-powerpc.inc

TUNEVALID[ppc405e] = "Enable ppc405e specific processor optimizations"
TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "ppc405e", "-mcpu=405fp", "", d)}"

AVAILTUNES += "ppc405e"
TUNE_FEATURES_tune-ppc405e = "m32 ppc405e fpu-hard"
TUNE_PKGARCH_tune-ppc440e = "ppc405e"
PACKAGE_EXTRA_ARCHS_tune-ppc405e = "${PACKAGE_EXTRA_ARCHS_tune-powerpc} ppc405e"

# glibc configure options to get ppc405e specific library (for sqrt)
GLIBC_EXTRA_OECONF += "${@bb.utils.contains("TUNE_FEATURES", "ppc405e", "-with-cpu=405fp", "", d)}"

And in my machine, should I be defining TARGET_CPU = "405fp" or "405e" ?

TARGET_CPU  = "405fp"
#tune for the 405e cpu
require conf/machine/include/tune-ppc405e.inc

The gcc compiler options for -mcpu=cpu_type can be one of '405' or '405fp'.

I can't get bitbake to build it for some reason, I keep getting errors like this:

$ bitbake -c fetchall core-image-minimal

    Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
    Following is the list of potential problems / advisories:

    Error, the PACKAGE_ARCHS variable does not contain TUNE_PKGARCH (${TUNE_PKGARCH_tune-ppc405e}).
ERROR: Execution of event handler 'check_sanity_eventhandler' failed
ERROR: Command execution failed: Exited with 1

Summary: There were 4 ERROR messages shown, returning a non-zero exit code.

Is this some how related to expanding the variable EXTRA_OECONF_FPU in gcc-cross-initial.inc (I'm working on a commit that is before Khem's recent rework on gcc-4.7)

EXTRA_OECONF = "--with-newlib \
		--without-headers \
		--disable-shared \
		--disable-threads \
		--disable-multilib \
		--disable-__cxa_atexit \
		--enable-languages=c \
                ${OPTSPACE} \
		--program-prefix=${TARGET_PREFIX} \
		--with-sysroot=${STAGING_DIR_TARGET} \
		--with-build-sysroot=${GCCCROSS_BUILDSYSROOT} \
		${EXTRA_OECONF_INITIAL} \
		${@base_contains('DISTRO_FEATURES', 'ld-is-gold', '--with-ld=${STAGING_BINDIR_TOOLCHAIN}/${TARGET_PREFIX}ld.bfd', '', d)} \
		${EXTRA_OECONF_FPU}"
