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