[Qemu-devel] [PATCH V3 1/2] tests/migration: Convert the boot block compilation script into Makefile |
Date: |
Thu, 15 Feb 2018 01:07:24 -0500 |
The x86 boot block header currently is generated with a shell script.
To better support other CPUs (e.g. aarch64), we convert the script
into Makefile. This allows us to 1) support cross-compilation easily; 2)
avoid creating a script file for every architecture.
