in repository openembedded-core.
commit 38cdd58b603db2e388457467fcd7a733f8f4f909
Author: Robert Yang <liezhi.yang at windriver.com>
AuthorDate: Sun Sep 18 00:39:30 2016 -0700
runqemu: improve finding of rootfs, kernel and dtb
* Search rootfs in the following order:
- IMAGE_NAME*.FSTYPE
- IMAGE_LINK_NAME*.FSTYPE
* Search kernel in the following order:
- QB_DEFAULT_KERNEL
- KERNEL_IMAGETYPE
- KERNEL_IMAGETYPE*
* Search dtb in the following order:
- QB_DTB
- QB_DTB*
- *.dtb
* Fix DTB, it should only work with "-kernel" option.
