The device names used by the bootloader differ from the names used by the kernel. What gets printed as bootdevice/bootfile here is simply the string that the bootloader passed to the kernel. We probably should change the names in the bootloader to be less confusing (i.e. use hdN instead of sdN like on x86). Personally I would drop the printfs here, but IIRC folks working on softraid wanted to keep them. > OpenBSD 6.6-current (GENERIC) #250: Sun Jan 12 08:43:32 MST 2020 > dera...@armv7.openbsd.org:/usr/src/sys/arch/armv7/compile/GENERIC > real mem = 477814784 (455MB) > avail mem = 458113024 (436MB) > mainbus0 at root: TI AM335x BeagleBone Black > cpu0 at mainbus0 mpidr 0: ARM Cortex-A8 r3p2 > cpu0: 32KB 64b/line 4-way L1 VIPT I-cache, 32KB 64b/line 4-way L1 D-cache > cpu0: 256KB 64b/line 8-way L2 cache > omap0 at mainbus0 > prcm0 at omap0 rev 0.2 > dmtimer0 at omap0 rev 3.1 > dmtimer1 at omap0 rev 3.1 > simplebus0 at mainbus0: "ocp" > simplebus1 at simplebus0: "l4_wkup" > "wkup_m3" at simplebus1 not configured > simplebus2 at simplebus1: "prcm" > "l4_per_cm" at simplebus2 not configured > "l4_wkup_cm" at simplebus2 not configured > "mpu_cm" at simplebus2 not configured > "l4_rtc_cm" at simplebus2 not configured > "gfx_l3_cm" at simplebus2 not configured > "l4_cefuse_cm" at simplebus2 not configured > simplebus3 at simplebus1: "scm" > syscon0 at simplebus3: "scm_conf" > pinctrl0 at simplebus3 > "wkup_m3_ipc" at simplebus3 not configured > "dma-router" at simplebus3 not configured > intc0 at simplebus0 rev 5.0 > "edma" at simplebus0 not configured > "tptc" at simplebus0 not configured > "tptc" at simplebus0 not configured > "tptc" at simplebus0 not configured > omgpio0 at simplebus0: rev 0.1 > gpio0 at omgpio0: 32 pins > omgpio1 at simplebus0: rev 0.1 > gpio1 at omgpio1: 32 pins > omgpio2 at simplebus0: rev 0.1 > gpio2 at omgpio2: 32 pins > omgpio3 at simplebus0: rev 0.1 > gpio3 at omgpio3: 32 pins > com0 at simplebus0: ti16750, 64 byte fifo > com0: console > tiiic0 at simplebus0 rev 0.11 > iic0 at tiiic0 > "ti,tps65217" at iic0 addr 0x24 not configured > "atmel,24c256" at iic0 addr 0x50 not configured > nxphdmi0 at iic0 addr 0x70: rev 0x0301 > nxphdmi0: no display detected > tiiic1 at simplebus0 rev 0.11 > iic1 at tiiic1 > "atmel,24c256" at iic1 addr 0x54 not configured > "atmel,24c256" at iic1 addr 0x55 not configured > "atmel,24c256" at iic1 addr 0x56 not configured > "atmel,24c256" at iic1 addr 0x57 not configured > ommmc0 at simplebus0 > sdmmc0 at ommmc0: 4-bit, sd high-speed, mmc high-speed > ommmc1 at simplebus0 > sdmmc1 at ommmc1: 1-bit > "spinlock" at simplebus0 not configured > omdog0 at simplebus0 rev 0.1 > "mailbox" at simplebus0 not configured > "timer" at simplebus0 not configured > "timer" at simplebus0 not configured > "timer" at simplebus0 not configured > "timer" at simplebus0 not configured > "timer" at simplebus0 not configured > "timer" at simplebus0 not configured > "timer" at simplebus0 not configured > "rtc" at simplebus0 not configured > "usb" at simplebus0 not configured > cpsw0 at simplebus0: version 1.12 (0), address 90:59:af:82:2e:7e > ukphy0 at cpsw0 phy 0: Generic IEEE 802.3u media interface, rev. 1: OUI > 0x0001f0, model 0x000f > "ocmcram" at simplebus0 not configured > amdisplay0 at simplebus0 > amdisplay0: no display attached. > "emif" at simplebus0 not configured > "sham" at simplebus0 not configured > "aes" at simplebus0 not configured > "mcasp" at simplebus0 not configured > "rng" at simplebus0 not configured > scsibus0 at sdmmc1: 2 targets, initiator 0 > sd0 at scsibus0 targ 1 lun 0: <SD/MMC, MMC02G, 0000> removable > sd0: 1832MB, 512 bytes/sector, 3751936 sectors > scsibus1 at sdmmc0: 2 targets, initiator 0 > sd1 at scsibus1 targ 1 lun 0: <SD/MMC, SU32G, 0080> removable > sd1: 30436MB, 512 bytes/sector, 62333952 sectors > vscsi0 at root > scsibus2 at vscsi0: 256 targets > softraid0 at root > scsibus3 at softraid0: 256 targets > bootfile: sd0a:/bsd > boot device: sd0 > root on sd1a (93aae518915c8841.a) swap on sd1b dump on sd1b > WARNING: CHECK AND RESET THE DATE! > >
