That seems to have done it, as far as 'bootarm.efi' is concerned.  The
output of 'dev' now shows:

  > dev
  hd0 (7600 MB): VenHw(E61D73B9-A384-4ACC-AEAB-82E828F3628B)/Usb(0x6,0x0)
    hd0a (2051 MB): 4.2BSD
    hd0e (18 MB): MSDOS
    hd0f (1027 MB): 4.2BSD
    hd0g (3473 MB): 4.2BSD
  hd1 (3688 MB): VenHw(E61D73B9-A384-4ACC-AEAB-82E828F3628B)/Usb(0x6,0x1)
  net0 xx:xx:xx:xx:xx:xx

  default: hd0a

and it is able then to boot netbsd directly.  Unfortunately, the system
is then plagued with the "sdhc0: cmd timeout" errors and cannot complete
booting.  Something involved in "mountcritlocal" bombs out with SIGSEGV
and it punts to single-user mode.

'disklabel' shows the opposite of what I'd expect and retains the "c is
whole disk" entry and claims "d is NetBSD part", even though I explicitly
set "d is whole disk, c is NetBSD part" through 'disklabel -i ld0'.


Netbooting with "boot net0:netbsd" now assumes "ld0a" is the root device
instead of "cpsw0" and it ends up with:

[...]

So, some progress, but things still aren't working right.  Definitely need
to dig out USB-uSD adapter to check/repair the SD card...
