Hi, Ben, Since the p5020ds you tested is a rev1 chip, I think the most possibility that SATA not work is due to a SATA erratum, which is fixed in rev1.1, we have a policy that patches for errata that are present only on early silicon revisions, typically only rev1 silicon will not send upstream. You can find the patch at below link: http://git.freescale.com/git/cgit.cgi/ppc/sdk/linux.git/commit/?id=b79a8a0528b8a0008cb76f339806b1200b5d8f63
Since it is not sent to upstream, it may need to be rebased if apply it to latest tree. Also there might be another issue(SATA & USB) if you test 64 bit kernel on p5020ds with DRR > 4G, we have a patch Sent to upstream, but not accepted yet. Link as below: http://patchwork.ozlabs.org/patch/179828/ There are online documents of SDK, for the p5020ds hardware please see the link: http://www.freescale.com/infocenter/index.jsp?topic=%2FQORIQSDK%2F2989554.html Best Regards, Shaohui Xie > -----Original Message----- > From: Benjamin Herrenschmidt [mailto:b...@kernel.crashing.org] > Sent: Thursday, May 16, 2013 12:48 PM > To: Liu Qiang-B32616; Xie Shaohui-B21989; Fleming Andy-AFLEMING > Cc: linuxppc-dev@lists.ozlabs.org; Kumar Gala > Subject: SATA FSL and upstreaming > > Hi folks ! > > So I was trying to use my 5020ds to test some stuff today.
