Supports building the Swift configuration on top of an op-build repository

swift-config-wrapper

This repository has the latest configuration files necessary to build OpenPower code for a Swift system:

• swift_defconfig (used by 'op-build' repo)
• swift.config (used by 'hostboot' repo)

Building a Swift Image

To build an image for a Swift system:

git clone --recursive  https://github.com/ibm-op-release/swift-config-wrapper.git
cd swift-config-wrapper
./setup_swift
cd op-build
. op-build-env && op-build swift_defconfig && op-build

See https://github.com/open-power/op-build/blob/master/README.md for more information on building an op-build repo.

Updating Swift Configuration Files

Updating swift_defconfig for op-build

To update swift_defconfig, make changes directly to "create_swift_defconfig.patch".

"./setup_switch" pulls down the witherspoon_defconfig file and then applies "create_swift_defconfig.patch" to it to create swift_defconfig. This allows any overall changes at the op-build level (like a new custom kernel level) to automatically be picked up when the op-build repo is built.

Updating the swift.config for hostboot

Simply make changes directly to "swift.config" and they will be applied when the hostboot repo/package is built.
