* Generate the domU partial dtb via disk_imageAyan Kumar Halder2021-12-211-12/+45
| | | | | | | | | | | | | | | | | | | | Similar to uboot-script-gen, disk_image invokes compile_merge_partial_dts to generate the domU partial dtbs. It copies the dtbs to /etc/xen. Added functions to cleanup the temporary files. Also removed 'set -e'. This was causing the script to terminate if any of the functions returned non zero. In our approach, the functions in common script will return 1 (on failure), and the caller (ie disk_image) will check the return code and do the appropriate cleanup. Moreover, 'set -e' cannot be relied upon to terminate the script if any function returns error. Thus, it is not very useful.

* Add *.cpio to the list of know rootfs typesAyan Kumar Halder2021-10-281-6/+12
| | | | | | | | | | | Yocto generates *.cpio images. Thus, it can be a valid type of rootfs image. Also, when an invalid rootfs image is detected, the script should exit immediately Signed-off-by: Ayan Kumar Halder <ayankuma@xilinx.com> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> Signed-off-by: Stefano Stabellini <stefano.stabellini@xilinx.com>
* Add an option to specify the alignment for the imageAyan Kumar Halder2021-10-181-2/+30
| | | | | | | | | | "petalinux-boot --qemu" when used with a sd image, expects the image to be of size which is power of 2. Thus, one needs to provide an option to disk_image to create images aligned to the next power of two.

* Introduce multiple partitions support to disk_imageStefano Stabellini2021-05-171-41/+96
| | | | | | | | | | | | | | | | | | Rootfses that should be written to disk as their own partition are called *_ROOTFS instead of *_RAMDISK. This change makes the config file clearer and more consistent. However it changes the current behavior as the Dom0 RAMDISK (not ROOTFS) was written to disk as its own partition before, and now it is not. In the case of uboot-script-gen, dom0less guests cannot access disk partitions yet (missing PV drivers support). Hence, if one or more domU ROOTFSes are specified, print an error and exit. For dom0, base the root= parameter generation on the presence of DOM0_ROOTFS.
