runqemu: refactor it and remove machine knowledge
Previously, runqemu had hard coded machine knowledge, which limited its
usage, for example, qemu can boot genericx86, but runqemu can't, we need
edit runqemu/runqemu-internal a lot if we want to boot genericx86.
Now bsp conf files can set vars to make it can be boot by runqemu, and
qemuboot.bbclass will save these info to DEPLOY_DIR_IMAGE/qemuboot.conf.
Please see qemuboot.bbclass' comments on how to set the vars.
* Re-write it in python3, which can reduce lines from 1239 to about 750
lines
* All the machine knowledges are gone
* All of the TUN_ARCH knowledge are gone
* All the previous options are preserved, and there is a new way to run
runqemu: (it doesn't need run "bitake -e" in such a case)
$ runqemu tmp/deploy/images/qemux86
or:
$ runqemu tmp/deploy/images/qemuarm/<image>.ext4
or:
$ runqemu tmp/deploy/images/qemuarm/qemuboot.conf
* Fixed audio support, not limited on x86 or x86_64
* Fix SLIRP mode, add help message, avoid mixing with tap
* Fix NFS boot, it will extract <image>.tar.bz2 or tar.gz to
DEPLOY_DIR_IMAGE/<image>-nfsroot when no NFS_DIR, and remove it after
stop.
* More bsps can be boot, such as genericx86 and genericx86-64.
* The patch for qemuzynq, qemuzynqmp, qemumicroblaze has been sent to
meta-xilinx' mailing list.
* I can't find any qemush4 bsp or how to build it, so it is not
considered atm.
