 My bad. I only take mx6 into consideration when I did this patch.


 (among other failed targets)

 I tried to fix it by including asm/arch-imx/cpu.h, but then got undefined 
 reference to is_cpu_type().

 Now is_cpu_type() is common to all i.MXes, but need this patch

 After applying the following patches, is_cpu_type should work.

 I already have patches 1 and 3 applied locally, and will probably send a 
 pull 
 request as soon as buildman finishes.  Let me know if you want me to send 
 that, and then you can send patch 2 through imx, or if you want me to pull 
 patches 1 and 3 out so all can go via imx.
 
 You can send pull request for patch 1 and 3. The 3 patches are independent on 
 each other.
 I'll repost patch 2 when the is_cpu_type patch set merged to uboot upstream 
 master branch with your Acked-by. Then imx or nand tree, both are ok.

Fine with me.
