It's a while since I did any work on a banana pi, so I thought I would try and
bring up NetBSD -9 on a BPI-M1.
I made a bootable sdcard following the instructions at:
https://wiki.netbsd.org/ports/evbarm/install_using_sysinst/
and everything came up as expected on a serial console:

The uboot script seemed a bit strange - things have changed over the last few
years and I wasn't sure what the efi boot process was, but it seemed to work
OK.
I decided to attach a SATA disk and get the system to boot from this.
Tried to use sysinst to do a custom partition of the disk and found a few
problems with sysinst getting confused in the partitioning process (will file
a send-pr later). In the end I manually partitioned and newfs'ed the disk,
created an fstab table and let sysinst install the software. I then copied to
boot stuff over from the sdcard to /boot (dos) and used fdisk to mark the dos
and netbsd areas in the partition table.

So far everything looked OK and I just needed to persuade the u-boot system to
use the hard disk (wd0) rather than the sdcard (ld0). The document above edits
the boot.cmd file and generates a boot.scr file. So I tried using a boot.cmd
file with:
scsi scan
scsi dev 0
setenv kernel netbsd-GENERIC.ub
fatload scsi 0:1 82000000 $kernel
bootm 82000000 root=wd0a console=fb
and then
mkubootimage -A arm -n armv7 -T script boot.cmd boot.scr
I copied the both files to the boot partition on the hard disk (and the
sdcard).

(at this point the system boots off the sdcard)
So clearly there is something wrong with the kernel image - yet this
boots OK from the sdcard and the image on the hard disk is identical - so some
other magic is needed. What's the efiboot bit? Can someone enlighten me as to
what I need to do...
Cheers,
Dave
