All, FYI Sinan Akman has reported that cassini does not compile for x86 any longer. Message included below. Does anyone have suggestions as to the best way to resolve this? Also are there any other lists that this should be forwarded to? Regards Richard -------- Original Message -------- Subject: Re: [PATCH] cassini: Use local-mac-address prom property for Cassini MAC address Date: Thu, 13 Jan 2011 20:28:54 -0500 From: Sinan Akman <sinan@writeme.com> To: richm@oldelvet.org.uk Richard, cassini doesn't compile now for x86 after : http://www.spinics.net/lists/sparclinux/msg07607.html pci_device_to_OF_node is not defined for all archs so perhaps you are better of leaving CONFIG_SPARC instead of having CONFIG_OF. Feel free to forward this to list (did this ever appear in lmkl or only sparclinux ?). If you have another patch on that and cc me I can compile test for you on x86. -- sinan On 06/01/2011 19:51, David Miller wrote: > From: Richard Mortimer<richm@oldelvet.org.uk> > Date: Thu, 06 Jan 2011 14:34:15 +0000 > >> > From 603b3377a6857448006c886f10c607d07c102b64 Mon Sep 17 00:00:00 2001 >> From: Richard Mortimer<richm@oldelvet.org.uk> >> Date: Thu, 6 Jan 2011 00:08:54 +0000 >> Subject: [PATCH] cassini: Use local-mac-address prom property for Cassini MAC address >> >> Fallback on the local-mac-address prom property if the Cassini device >> does not have an address programmed in the VPD ROM.
