! 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.
! 57: The boot ROM will only try to load these files off an SD card unless a
! 58: special config.txt value is set to irreversibly enable USB boot mode.
! 59: These files are present in the install media but there is no driver
! 60: for SD/MMC yet so a USB disk drive and manual steps are required.
! 61: </p>
! 62:
! 63: <p>
! 64: Opteron A1100 machines on the other hand come with a UEFI firmware
! 65: that includes a device tree and can boot off SATA or USB devices without
! 66: board specific boot files on the system disk.

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