The generators themselves probably not, but the definition of all those registers is from hardware. These kind of code generators convert input source files that describe the hardware into C header files for the software. But I expect AMD would be skittish about open-sourcing anything that could even remotely be construed as HDL, even if it's just dry lists of registers. Open sourcing the drivers is one thing, but the hardware itself is another.
