Cleanup the PowerPC tunings to match the new tuning README file.
Default PowerPC to using TUNE_PKGARCH = ${TUNE_PKGARCH_tune-<tune>}
Fix AVAILTUNE settings in ppc603e, and ppce500mc to be addative.
Correct potentially overlapping "spe" definitions in ppce500 and ppce500v2.

- Initial revision
|
|
|
|
There are 4 primary PowerPC ABIs.
|
|
# *) Hard/Soft Floating Point
|
|
# *) 32-bit/64-bit
|
|
|
|
TUNE_ARCH is defined as either "powerpc" or "powerpc64" based on the m32
|
|
or m64 feature.
|
|
|
|
May of the PowerPC package archictures are based on legacy Linux names.
|
|
However, a general naming scheme should be similar to: ppc[64][<family>][-nf].
|
|
(Note: the default package architectures are "powerpc" and "powerpc64".)
|
|
|
|
TUNE_PKGARCH is defined as TUNE_PKGARCH_tune-${DEFAULTTUNE}. All
|
|
PowerPC tunings are required to define TUNE_PKGARCH_tune-<tune>.
