Subject: [PATCH v3 2/4] powerpc: Generic device tree for all AmigaOne boards

From: "Gerhard Pircher" <[email-masked]>
Date: Tue, 10 Feb 2009 23:26:03 +0100

This device tree does not provide the correct CPU name, as various CPU
models and revisions are used in AmigaOnes. Also the PCI root node does
not contain a interrupt mapping property, as all boards have different
interrupt routing. However the kernel can do a 1:1 mapping of all PCI
interrupts, as only i8259 legacy interrupts are used.
