Subject: Patchset to establish sanity in Xilinx Virtex support
Date: Sun, 15 Apr 2007 01:27:37 -0600 [thread overview]
Message-ID: <1176622062492-git-send-email-grant.likely@secretlab.ca> (raw)
The Virtex support in Linus' tree is a mess. When I ported the common
devices over to using the platform bus I tried the use the ppc_sys
infrastructure. ppc_sys is intended for SoCs that have a fixed set of
devices. It is the *wrong* approach for FPGA support, and I made a
royal mess of things. This patch set fixes that problem and makes
a number of other changes that make supporting Virtex boards easier.
I do know that changes to arch/ppc are frowned upon at the moment. However,
4xx support in arch/powerpc is not merged yet, and Virtex support needs
additional work beyond that. I suspect that arch/ppc support for the
4xx parts is going to need to stay alive for the next 2-3 kernel releases
anyway while arch/powerpc support stablizes. Getting these patches in
will make it easier to support the Virtex ports while I hack on getting
arch/powerpc stuff figured out.
