[Answering my own mail]

It turns out that there is - this is how you prompt it into 'pretend
to be jflash' mode. So I've put that back.

Then I noticed that the test for 'was I called as jflash' doesn't
work if it is called as ./jflashmm or /usr/bin/jflashmm so I've fixed
that in SVN.

My initial tests show that it doesn't work very well on loon2 (as
expected). I get:

#sudo ./jflashmm Balloon2 -h

Base Address set to 0
Platform Balloon2
jtagSetDeviceAttributes
Testing port address 3bc ... found.
Setting LPT port to 0x3bc
id = 0x0
Part found    = 0x0
Expected Part = 0x9261013
Failed to identify device.

I haven't looked at what's going on here. Any clues?

Apparently not, but some peering at the code has got me some idea of
how it works. Dave, care to start a wiki page outlining the basic
stuff on bflash/jflash mode and syntax capabilites (i.e. what is
expected to work/not work).
