6. Did you build your own toolchain?

Yes using the crosstool however prior to that I had a rather painful
experience attempting to build it all up myself based on gcc 2.95
ultimately resulting in deciding DENX had done a better job (they seem
pretty good if you want to buy support too) than I had so...

7. If not, where did it come from?

Previously used DENX toolchain which was based upon gcc 2.95.

8. What is your development environment (editors, tools, debuggers, etc.)?

Editors - mostly emacs on various platforms with a little vi.
Tools - mostly gnu tools on Powerbook laptop running Debian although
also cross toolchain on Intel GNU/Linux. Xygwin and some Xilinx.
Debuggers - gdb and xmd mostly. Some custom stuff too.

9. I have an Abatron, any useful magic I should know?

You can send it to me if you want to :-).

10. How do you manage building, configuring and delivering user-mode
software for the target?

Scripts and some stuff I will automate.

11. Please pass along any comments on non-floating point -capable
processors:

I was recently having problems with soft float on 405D however this
turned out to be a bug in the memory management code which has been
fixed since the release I had originally based my patches upon.
Upgrading seems to have solved that.

Floating point is being done via userspace library emulation however I
am compiling in the soft float support just in case.

Cheers,

Jon.
