What about i.MX6DL SABRE Auto ? Is it in main-line too ?  If yes, which config file should I use ?

By looking at boards.cfg, I could find  mx6qsabreauto, ma6dlsabrelite, 
nitrogen6dl...,  but there is no something like mx6dlsabreauto.

The support of it is also in freesacle git mentioned by Thierry

http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/?h=imx_v2009.08_3.0.35_4.1.0&id=c9b49bf8b7c64e628ce2625272e4deb65b8c8720

Thanks,
Miao
