Subject: Re: SSB AI support code ([RFC3/11] SSB irqflag device op)
Date: Wed, 09 Feb 2011 16:32:53 +0200 [thread overview]
Message-ID: <1297261973.18053.20.camel@dev.znau.edu.ua> (raw)
In-Reply-To: <1297258590.17400.37.camel@dev.znau.edu.ua>
From: George Kashperko <george@znau.edu.ua>
SB- and AI-style buses read irq flags from different locations.
SB-ones read them from TPSFLAG whereas AI-ones from core oob register.
In order to support both SB- and AI-style buses transparently
irq flag accessor is implemented as ssb device op.
