Doing that now - It's past the expat build, but it will take a while to build the entire toolchain on an SD card :) > > FYI rtems-tools needs updating to bump the has to something recent > enough to get the aarch64 kcu105_qemu tester configuration and a > number of Coverity fixes.

My first thought was "what are the > other 20%?" :) Probably refers to Chromebooks and Windows ARM devices like the Microsoft SQ1 processor. We have a Mac with a M1 CPU.. Eventually I'll have to try to generate an RTEMS toolchain on it.
