   2  * Broadcom SiliconBackplane MIPS definitions
   3  *
   4  * SB MIPS cores are custom MIPS32 processors with SiliconBackplane
   5  * OCP interfaces. The CP0 processor ID is 0x00024000, where bits
   6  * 23:16 mean Broadcom and bits 15:8 mean a MIPS core with an OCP
   7  * interface. The core revision is stored in the SB ID register in SB
   8  * configuration space.
