Just taking a quick look at the supplied Linux source it seems to use the 
standard r3k_foo functions from the MIPS specific mm and cache source.  The 
supplied precompiled GNU tools point towards a standard MIPS build too.  
Unfortunately the OEM who made the Linux source available has missed some 
important things.  Not insurmountable.

I have ordered a Minitar and soon hope to be poking around it with a homebrew 
JTAG kit and the tools on http://openwince.sf.net/jtag .

Do you know if the EJTAG spec allows you to peek and poke memory in a device 
so you could conceivably program the FLASH without the BSDL file?
