From 85aecac8d2893372c618bac373e2de9cf102dfbc Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 13 Jun 2007 14:53:00 +1000 Subject: [POWERPC] Consolidate cuboot initialization code The various cuboot platforms (i.e. pre-device tree aware u-boot for 83xx, 85xx and Ebony) share a certain amount of code for parsing the boot parameters. To a certain extent that's inevitable, since they platforms have different definitions of the bd_t structure. However, with some macro work and a helper function, this patch improves the situation a bit. In the process, this fixes a bug on Ebony, which was incorrectly handling the parameters passed form u-boot for the command line (the bug was copied from 83xx and 85xx which have subsequently been fixed).
