To simplify machine init and as the soc_device struct is not used as the parent for on-chip devices anymore, move SoC detection to its own driver. Change in dmesg: - before: DMA: preallocated 256 KiB pool for atomic coherent allocations AT91: Detected SoC family: sama5d2 AT91: Detected SoC: sama5d27, revision 0 No ATAGs? clocksource: tcb_clksrc: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 184217874325 ns at_xdmac f0010000.dma-controller: 16 channels, mapped at 0xe085b000 SCSI subsystem initialized - after: DMA: preallocated 256 KiB pool for atomic coherent allocations No ATAGs? clocksource: tcb_clksrc: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 184217874325 ns at_xdmac f0010000.dma-controller: 16 channels, mapped at 0xe0859000 AT91: Detected SoC family: sama5d2 AT91: Detected SoC: sama5d27, revision 0 SCSI subsystem initialized Suggested-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Nicolas Ferre <nicolas.ferre@microchip.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
