// Date:         2000-02-04
// Purpose:      Provide PPC60x register definitions
// Description:  Provide PPC60x register definitions
//               The short difinitions (sans CYGARC_REG_) are exported only
//               if CYGARC_HAL_COMMON_EXPORT_CPU_MACROS is defined.
// Usage:        Included via the acrhitecture register header:
//               #include <cyg/hal/ppc_regs.h>
//               ...
//
