5A lot of explanation needed, will do when known.

7The score/cpu/sparc64 contains only code that can execute without accessing
8privileged registers or using privileged instructions. This was done because
9the privileged registers differ between the sun4u and sun4v models.

11The model specific and privileged code that would normally be found in
12score/cpu/sparc64 resides in libcpu/sparc64/@RTEMS_CPU_MODEL@/score or in
13libcpu/sparc64/shared/score directory. This is primarily the interrupt
14handling code.
