RTEMS ARMv8 Query

[Xu Ray]

I think you already know about
https://docs.rtems.org/doc-current/share/rtems/html/ and
https://docs.rtems.org/rsb/
But before you start from scratch. You can try to download the ARM
toolchain for rtems 11. And compare the building instruction/configuration
 with your current working V8 gnu toolchain.  There are good chance that
rtems11 toolchain might generate v8 code....
