Paul Mundt	9ad62ec4f7	sh: Fix up early PCI PERR/SERR IRQ handling. ... This adds support for handling early PERR/SERR triggering in between controller registration and the initial bus scan. Buggy cards end up asserting these as soon as the M66EN scan is undertaken, resulting in an early crash. Signed-off-by: Paul Mundt <lethal@linux-sh.org>	2010-02-03 16:46:20 +09:00
Paul Mundt	ef407beefb	sh: Hook up ERR/PERR/SERR detection for SH7780 PCI host controllers. ... These were never handled before, so implement some common infrastructure to support them, then make use of that in the SH7780-specific code. In practice there is little here that can not be generalized for SH4 parts, which will be an incremental change as the 7780/7751 code is gradually unified.

Paul Mundt	85b59f5bb2	sh: Enable PCI66 support for SH7780 host controller. ... This adds some helper glue for scanning the bus and determining if all of the devices are 66MHz capable or not before flipping on 66MHz mode. This isn't quite to spec, but it's fairly consistent with what other embedded controllers end up having to do. Scanning code cribbed from the MIPS txx9 PCI code.
