If you consider the fact that besides fash burning you may also want
to have a working hardware debugger, you should go for a BDI2000 -
especially for Linux, when MMU support is needed.

Tha't mostly because they are just working fine for the class of
devices they have been designed for. The MPC5200 has no BDM
interface, but a JTAG based debug interface for which it is
impossible to get the necessary specifications without an NDA - an
NDA which prevents any implementation under GPL. Complain with
Freescale.

And they have no idea how do deal with virtual addresses.

It may be difficult to get the required documentation from Freescale,
and then you will probably spend more money (in terms of your time)
than you have to pay for a working tool (BDI2000).
