Subject: [PATCH 3/10] Re-organize Kconfig code for 4xx in arch/powerpc
Date: Thu, 22 Mar 2007 20:22:02 +1100 (EST) [thread overview]
Message-ID: <20070322092202.16529DDF3D@ozlabs.org> (raw)
In-Reply-To: <20070322060630.GB16993@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.
