commit ca30b3e9e11b28ced7987e94e1f784ba5f85b366 Author: Vladimir Serbinenko phcoder@gmail.com Date: Sat Jan 11 07:46:50 2014 +0100
ibexpeak / bd82x6x: Make SATA mode user-visible option.
Ability to choose compatibility mode is interesting for testing payloads and OS for compatibility with older systems.
As per comments "ide_legacy_combined # TODO: Does nothing since generations, remove from sb code?" The "combined" mode was removed. It wasn't used by any mobo and the code for it is almost identical to IDE one other than few bits relating to interrupt handling and ISA mode.
