# iPXE is configured by setting config macros in the source tree. The repo
# contains a number of config headers in ipxe/src/config/*.h which contain
# defaults. These defaults can be overridden by creating a corresponding header
# in ipxe/src/config/local.
# For example, the source repo contains ipxe/src/config/general.h, which
# explicitly does not define NET_PROTO_IPV6. To enable IPv6 support in iPXE we
# need to create ipxe/src/config/local/general.h and define NET_PROTO_IPV6 in
# that header.
# The following allows OVB to keep iPXE configuration under ipxe-config in this
# repo, and copies it into place in the iPXE repo during build.
# config_headers is a list of the filenames of all overridden headers in ipxe-config/
