[PATCH v4.5 24/29] include: split target_long definition from cpu-defs

Posted by Richard Henderson 2 years, 11 months ago

From: Alex Bennée <alex.bennee@linaro.org>

While we will continue to include this via cpu-defs it is useful to be
able to define this separately for 32 and 64 bit versions of an
otherwise target independent compilation unit.
