1.4 jsg 43: The current target platforms are Pine64, Raspberry Pi 3 and Opteron A1100.

47: The Pine64 currently requires an image based on a non-redistributable
48: boot0 file from Allwinner to be installed on the system disk.
49: This will hopefully be resolved by a replacement in a future U-Boot
50: release. The install media does not include these boot images or
51: a Pine64 device tree.
52: </p>
53:
54: <p>
55: The Raspberry Pi 3 requires closed but redistributable files on the
56: system disk to load into the VC4 GPU which starts the ARM cores.
1.7 jsg 57: By default the boot ROM will only try to load these files off an SD card.
1.6 jsg 58: These files are present in the install media but there is no driver
59: for SD/MMC yet so a USB disk drive and manual steps are required.
1.7 jsg 60: To load the firmware off the SD card and have the root disk on USB
61: after installing OpenBSD reboot and interrupt U-Boot before the timeout
62: expires and instruct U-Boot to prefer USB over the SD card:
1.6 jsg 63: </p>
1.7 jsg 64:
65: <blockquote><pre>
66: Hit any key to stop autoboot: 0
67: U-Boot> setenv boot_targets usb0 mmc0 pxe dhcp
68: U-Boot> saveenv
69: U-Boot> boot
70: </pre></blockquote>
1.6 jsg 71:
72: <p>
73: Opteron A1100 machines on the other hand come with a UEFI firmware
74: that includes a device tree and can boot off SATA or USB devices without
75: board specific boot files on the system disk.

82: OpenBSD/arm64 bundles various platforms sharing the 64-bit ARM
83: architecture. Due to the fact that there are many System on a
84: Chips (SoC) around, OpenBSD/arm64 differentiates between various
85: SoCs and may have a different level of support between them.
