Thanks, Will.

This makes the kernel to boot again on my mx28evk, so:

Tested-by: Fabio Estevam <fabio.estevam at freescale.com>

There are still other issues, which seem to be unrelated to this fix though:

I can see the Linux logo and LED activity on my board, but no serial console.

Applying Shawn's patch:

diff --git a/arch/arm/boot/compressed/debug.S
b/arch/arm/boot/compressed/debug.S
index bdb0e25..6e8382d 100644
--- a/arch/arm/boot/compressed/debug.S
+++ b/arch/arm/boot/compressed/debug.S
@@ -1,4 +1,5 @@
 #include <linux/linkage.h>
+#include <asm/assembler.h>

 #include CONFIG_DEBUG_LL_INCLUDE

and turning on earlyprintk I see kernel booting and it stops at:

[    5.311281] TCP: cubic registered
[    5.315000] NET: Registered protocol family 17
[    5.320843] Key type dns_resolver registered
[    5.325750] turn off boot console earlycon0
