Subject: [PATCH 13/14] Re-organize Kconfig code for 4xx in arch/powerpc
Date: Tue, 20 Feb 2007 13:12:36 +1100 (EST)	[thread overview]
Message-ID: <20070220021236.3609EDDD0A@ozlabs.org> (raw)
In-Reply-To: <20070220020837.GF17818@localhost.localdomain>

Now that we always take a device tree in arch/powerpc, there's no good
reason not to allow a single kernel to support multiple embedded 4xx
boards - the correct platform code can be selected based on the device
tree information.

Therefore, this patch re-arranges the 4xx Kconfig code to allow this.
In addition we:
	- use "select" instead of depends to configure the correct
	  config options for specific 4xx CPUs and workarounds, which
	  makes the information about specific boards and CPUs less
	  scattered.
	- Some old, unused (in arch/powerpc) config options are
	  removed: WANT_EARLY_SERIAL, IBM_OCP, etc.
