My Sphinx doesn't like this:

Warning, treated as error:
/home/petmay01/linaro/qemu-from-laptop/qemu/docs/system/target-arm.rst:using
"math" markup without a Sphinx math extension active, please use one
of the math extensions described at
http://sphinx-doc.org/en/master/ext/math.html

This is all down to the I2C/I2S usage of superscript; this fixes it:
