* arm64: dcc: simplify accessorsMark Rutland2016-09-091-10/+4Star
| | | | | | | | | | | | | | A while back we added {read,write}_sysreg accessors to handle accesses to system registers, without the usual boilerplate asm volatile, temporary variable, etc. This patch makes use of these in the arm64 DCC accessors to make the code shorter and clearer.
