[oe] [STABLE][PATCH] zaurus: unbreak build of initramfs-kexecboot-image (thus others too...)

[Andrea Adami]

Please revert this bit:

-IMAGE_FSTYPES += " cpio.gz"
+IMAGE_FSTYPES = "cpio.gz"

I forgot that in stable the insane installkit is generated...and it
needs tar.gz initramfs image.

Proper solution would be to full sync zaurus-2.6.inc et co., but
personally I think we should leave it as 'memorial'.

Regards

Andrea
