I'm doing this at the moment - using the eCos based Red Hat embedded
monitor called 'RedBoot'.

eCos information can be found here: 
http://sources.redhat.com/ecos/
and preliminary RedBoot information is available off this page:
http://sources.redhat.com/ecos/docs-latest/

The monitor also provides flash programming (assuming the board
supports it) and GDB debugging, and has provision for the early printk
magic (but that hasn't been wired up yet for the calls used by
Linux/SH). There's also some issues with argument passing that need to
be sorted out.



We (as in the eCos/RedBoot engineers) have been plotting on trying to
persuade you to try out RedBoot on your platforms. It is already
ported to Hitachi's EDK7708 and the CqREEK 7708 and porting it to
other platforms should not be too painful (I'm somewhat biased from
having worked with it so long, but most people should be able to write
a port in a week or two).

However, seeing as I'm still working on fleshing out the porting
documentation (http://sources.redhat.com/ecos/docs-latest/porting/),
and the RedBoot documentation is still a bit rough, asking anyone to
try out eCos/RedBoot has seemed a little premature.

But now that you are bringing up TFTP boot capabilities, I thought I
would let you know about RedBoot. It only supports a single PCMCIA
netcard at the moment, but more are bound to follow.
