Subject: [PATCH 01/10] omap: Use separate init_irq functions to avoid cpu_is_omap tests early
Date: Mon, 28 Mar 2011 15:21:28 -0700 [thread overview]
Message-ID: <20110328222128.4046.70846.stgit@baageli.muru.com> (raw)
In-Reply-To: <20110328221501.4046.41079.stgit@baageli.muru.com>
This allows us to remove cpu_is_omap calls from init_irq functions
and the irq handler. There should not be any need for cpu_is_omap
as at this point we only care about SoC generation, and not about
subcategories.
The main reason for the patch is that we want to initialize only
minimal omap specific code from the init_early call, and this and
the following patches get us closer to that goal.

Subject: [PATCH 01/10] omap: Use separate init_irq functions to avoid cpu_is_omap tests early
Date: Mon, 28 Mar 2011 15:21:28 -0700 [thread overview]
Message-ID: <20110328222128.4046.70846.stgit@baageli.muru.com> (raw)
In-Reply-To: <20110328221501.4046.41079.stgit@baageli.muru.com>
This allows us to remove cpu_is_omap calls from init_irq functions
and the irq handler. There should not be any need for cpu_is_omap
as at this point we only care about SoC generation, and not about
subcategories.
The main reason for the patch is that we want to initialize only
minimal omap specific code from the init_early call, and this and
the following patches get us closer to that goal.
