Subject: Re: [PATCH v2] Add basic support from ARM Versatile/PB
Date: Mon, 11 Oct 2010 20:20:46 +0400 [thread overview]
Message-ID: <AANLkTi=yZZQ=cCoAfs0n2YwgZJtZfSOXc7xB-SBToph5@mail.gmail.com> (raw)
In-Reply-To: <20101011150644.32683.47820.stgit@zaytsev.su>
It seems that I've been wrong, and the real versatile/pb board also
provides smc91c111. I've been confused my the naming diffirences
between barebox and Linux. I'll send an updated patch soon.
