2010-10-21[ARM] Kirkwood: restrict the scope of the PCIe reset workaroundNicolas Pitre
Commit 21f0ba90a447 "orion/kirkwood: reset PCIe unit on boot" made the reset of the PCIe unit unconditional. While this may fix problems on some targets, this also causes problems on other targets. Saeed Bishara <saeed@marvell.com> said about the original problem: "We couln't pinpoint the root cause of this issue, actually we failed to reproduce that issue." So let's restrict the reset of the PCIe unit only to the target where the original problem was observed. Signed-off-by: Nicolas Pitre <nico@fluxnic.net>
2010-07-16[ARM] orion/kirkwood: reset PCIe unit on bootOlaf Rempel
Patch found in QNAPs vendor source package, with some cleanups (proper defines, shortened max. timeout from 1s to 200ms). Without this patch the PCIe SATA controller (Marvell 88sx7042/sata_mv) in my QNAP TS-419P (Marvell 88f6281/Kirkwood) stops working after a few minutes. The symptomes are described in this thread: http://marc.info/?l=linux-ide&m=124822863706181&w=2 [ Note: this is a workaround in need of a better analysis/solution -- NP ] Acked-by: Saeed Bishara <saeed@marvell.com> Tested-by: Bernhard R.

2008-06-22[ARM] Orion: PCIe x4/x1 detection supportLennert Buytenhek
The Discovery Duo (MV78xx0) has two x4 PCIe ports which can either be used in x4 mode or in quad x1 mode. This patch adds an accessor function to the generic plat-orion PCIe handling code to detect in which of the two modes we're running (which is determined by strap pins and/or configured by the bootloader).
