[U-Boot] [POWERPC][BUG] ramdisk: u-boot no longer boots a ramdisk with Linux 2.6.27-rc4

[Heiko Schocher <hs@denx.de>]

Hello Kumar,

I actually trying to boot a Linux 2.6.27-rc4 Kernel with a Ramdisk
and actual u-boot on a MPC82xx based board. And what should I say,
it doesnt work anymore :-(

Reason is the following commit:

http://git.denx.de/?p=u-boot.git;a=commitdiff;h=2a1a2cb6e2b87ee550e6f27b647d23331dfd5e1b#patch3

After this commit, u-boot no longer deletes the mem reservation
for the initrd in Flash, what stops Linux from booting.

So I did the following, but maybe there is a better way for it?

diff --git a/common/fdt_support.c b/common/fdt_support.c
index a7773ab..a69f001 100644
--- a/common/fdt_support.c
+++ b/common/fdt_support.c
@@ -215,8 +215,6 @@ int fdt_chosen(void *fdt, ulong initrd_start, ulong initrd_end, int force)
 		}
 	}

-	fdt_initrd(fdt, initrd_start, initrd_end, force);
-
 #ifdef CONFIG_OF_STDOUT_VIA_ALIAS
 	path = fdt_getprop(fdt, nodeoffset, "linux,stdout-path", NULL);
 	if ((path == NULL) || force)

With this patch Linux boots fine again with the Ramdisk ...

Do you know, why fdt_chosen() is creating a dummy entry for the initrd,
when later fdt_initrd() is again called with the right parameters?

I think, we can drop this!

bye,
Heiko
