[edk2-devel] [Patch 1/2 V2] BaseTools: Convert Split tool to python
Bob Feng

Wed Jan 13 10:19:58 UTC 2021
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3165
There are 2 reasons to convert Split tool from C to Python.
1. We are in the process of moving the Basetools Python code
to a separate repository. But there still are many C tools under
edk2/BaseTools. To make all Basetools be in the separate repo,
we can convert the C tools to Python tools.
2. The original Split tool is very slow. This python tool can reduce
90% time.
