That will ease review of the changes. The only changes are: - replace all @2.0 by 4.0 $ sed -i 's/@2\.0/@4\.0/g' */4.0/*.hal - replace all licence 2016 by 2018 $ sed -i 's/2016/2018/g' */4.0/*.hal Moving the .hal in a subfolder forces the package name and the namespace to change. This mean that the audio HAL 2.0 and 4.0 will not be consider different version of the same HAL but two different HALs. As a result to minimize code change due to tight deadline, keep the 4.0 core in the audio folder. Bug: 38184704 Test: hardware/interfaces/update-makefiles.sh Change-Id: I7c7a826270c9933091f037b795806787e1284583 Signed-off-by: Kevin Rocard <krocard@google.com>
