From 2a1a2cb6e2b87ee550e6f27b647d23331dfd5e1b Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Fri, 15 Aug 2008 08:24:43 -0500 Subject: fdt: refactor initrd related code Created a new fdt_initrd() to deal with setting the initrd properties in the device tree and fixing up the mem reserve. We can use this both in the choosen node handling and lets us remove some duplicated code when we fixup the initrd info in bootm on PPC.
