From: Serge Semin <sergey.se...@baikalelectronics.ru> Indeed according to the P5600/P6000 manual the MAAR pair register address field either takes [12:31] bits for 32-bits non-XPA systems and [12:35] otherwise. In any case the current address mask is just wrong for 64-bit and 32-bits XPA chips. So lets extend it to 39-bits value. This shall cover the 64-bits architecture and systems with XPA enabled, and won't cause any problem for non-XPA 32-bit systems, since the value will be just truncated when written to the 32-bits register.
