+
+Cross-compiling to RTEMS versions 4.9, 4.10 or 5 is supported

+(aka. **os: ubuntu-20.04** with GitHub Actions,
+**dist: focal** with Travis-CI or
+**image: ubuntu:focal** with GitLab CI/CD).
+
+## Cross Compilation
+
+Setting the `CI_CROSS_TARGETS` environment variable enables cross-compiling
+from Linux to the provided targets architectures.
+The value of the environment variable must  contain the EPICS architecture
+and - depending on the target - may contain additional information like
+the compiler prefix to be used or the version of the target OS.
+
+Multiple cross-targets can be added to the `CI_CROSS_TARGETS` variable
+by separating them with a colon (`:`) character.
+
+For example, possible values are:
+
+- linux-aarch64
+- linux-arm@arm-linux-gnueabi
+- linux-arm@arm-linux-gnueabihf
+- linux-ppc
+- linux-ppc64
