obmc-phosphor-image: Don't build .cpio.lzma.u-boot
For most incremental builds, the critical path is generating a new
installed obmc-phosphor-image fs, then compressing it to put into a
.lzma.u-boot container. However, the latter step doesn't seem necessary
except for the out-of-kernel initrd (obmc-phosphor-initramfs) because
obmc-phosphor-image is packaged as a squashfs-xz and not seen by U-Boot.
qemu.inc has its own IMAGE_FSTYPE appends, so qemuarm builds should not
be affected.
This reduces incremental build time by about a third, when doing
'bitbake obmc-phosphor-image' with no changes.
before:
150.74s user 66.01s system 148% cpu 2:25.96 total
after:
94.78s user 64.87s system 159% cpu 1:39.97 total
This reflects the removal of the single-threaded, CPU-bound 'lzma'
invocation from the critical path.
Netbootable images can still by generated by adding:
IMAGE_FSTYPES += "cpio.${INITRAMFS_CTYPE}.u-boot"
to local.conf.
