Yes but you must document every parameter which your generate do. The better
way is
document only parameters which you want use.

We can optimize now. I made new version of my generator u-boot_v3_00_a
(monstr.eu)
where you can simply add parameter which you want to use.
If you want use any parameter add it.
For microblaze cpu - line 1184.
And for others peripherals lines 926-980. (The last parameter of function call).
Which parameters do you want for PPC405, Grant?

Michal Simek
This is example of generator.
