runqemu: add process of option QB_NFSROOTFS_EXTRA_OPT
This extra options to be appended to the nfs rootfs options in kernel boot arg. Example config with qemuppc64 in machine config: add r/w size in the nfs rootfs extra option: QB_NFSROOTFS_EXTRA_OPT = "wsize=524288,rsize=524288" re-build and runqemu with nfs again, we can observe the kernel command line added our defined value in QB_NFSROOTFS_EXTRA_OPT: Kernel command line: root=/dev/nfs nfsroot=10.0.2.2:/home/xchen5/testing/build/tmp-glibc/deploy/images/qemuppc64/testnfs,nfsvers=3,port=3049,tcp,mountport=3048,wsize=524288,rsize=524288 rw mem=256M ip=dhcp console=hvc0 console=hvc0 nohugevmalloc (From OE-Core rev: 43a97f5bf3f90c5c1fd603f7dca2b3db2c0e3040) Signed-off-by: Xiangyu Chen <xiangyu.chen@windriver.com> Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
