# Packaging AMD and Intel microcode together is specific to Bottlerocket, and
# RPM only allows one URL field per package, so this is about as accurate as we
# can be. The real upstream URLs for AMD and Intel microcode are given below in
# the subpackage definitions.
URL: https://github.com/bottlerocket-os/bottlerocket/tree/develop/packages/microcode

# We use Amazon Linux 2 as our upstream for microcode updates.
