Subject: [U-Boot] [PATCH] OpenRD: Bring PCIe endpoint out of reset
Date: Tue, 20 Apr 2010 11:21:08 +0530 [thread overview]
Message-ID: <1271742668-2424-1-git-send-email-tanmay.upadhyay@einfochips.com> (raw)
In-Reply-To: <no>
There exists PCIe endpoints(not all) that remains in reset state till
PERST# line (A11 on the PCIe connector) is hold low. They come out of
reset only when this line is high.
In case of OpenRD, this line was in tri-state. So, some of the PCIe
devices would never appear on the PCIe bus. This patch makes PERST#
line high while booting to bring such PCIe devices out of reset.
XGI Vollari Z11 GPU and Intel WiFi 4965 are the ones who doesn't care
about this line. Where as Broadcom's BCM970012 won't appear on the PCIe
bus until PERST# is high. With this patch both kinds of device would
appear on the PCIe bus.
