Hi Dave,

I'll remove the bugfix (patch 8) and the CMR reading code but only keep what is
required for KVM TDX in the next version.

I updated the script and attached here so that I can have a lore link of the
script which can be used to reproduce the generated code in the next version.

It only has CMR part removed thus is not interesting to read.  Thanks.
