SPARC Processor Address Mapping
The SPARC processor always boots from address 0x0. There are two
address mappings for the SPARC processor, depending on the system
implementation.

In System with an External Master Processor
DMN-8600 SPARC processors boot from SDRAM — the external master
must load SPARC boot code into SDRAM via the DMN-8600 device’s
Host Interface.
