[PULL 25/35] target/arm: Add Cortex-R52 IMPDEF sysregs
Posted by Peter Maydell 1 year, 1 month ago 
Add the Cortex-R52 IMPDEF sysregs, by defining them here and
also by enabling the AUXCR feature which defines the ACTLR
and HACTLR registers. As is our usual practice, we make these
simple reads-as-zero stubs for now.
