This adds an 'NCPUS' generic parameter to the soc module, which then includes that many CPU cores. The cores have separate addresses on the DMI interconnect, meaning that external JTAG debug tools can view and control the state of each core individually. The syscon module has a new 'cpu_ctrl' register, where byte 0 contains individual enable bits for each core, and byte 1 indicates the number of cores. If a core's enable bit is clear, the core is held in reset. On system reset, the enable byte is set to 0x01, so only core 0 is active. Signed-off-by: Paul Mackerras <paulus@ozlabs.org> |
