Subject: [PATCH v3 0/3] [ARM] tegra: PCI Express support
Date: Mon, 27 Sep 2010 11:26:31 +0200 [thread overview]
Message-ID: <cover.1285579189.git.mike@compulab.co.il> (raw)
These patches enable PCI Express support on Tegra2.
The implementation is based on original NVidia code from (1), but it
is heavily reworked to avoid custom PCI enumeration and make the code
more Linux friendly.
This implementation assumes that the PCIe subsystem is fully powered
and ungated by the bootloader.

v3 changes:
* Fix spelling: s/_OFSET/_OFFSET/
* Make Harmony PCIe initialization multi-platform friendly
v2 changes:
* Update PCIe clocks implementation as per Colin and Gary suggestions
* Update I/O space access as suggested by Arnd and Russell.
* Remove debug leftovers and unify error reporting
