From 56844a22b76c719e600047e23b80465a44d76abd Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Thu, 11 Sep 2008 08:11:23 +0200 Subject: powerpc: Fix bootm to boot up again with a Ramdisk Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen, and this stopped Linux from booting with a Ramdisk. This patch fixes this, by deleting the useless dummy mem reservation. When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now added to of_size, so we dont need anymore a dummy mem reservation. I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based system (=0x44 bytes) and rounded it up to 0x80).
