[yocto] [meta-raspberrypi] u-boot doesnt boot kernel

[Hammad Ahmed]

Hi,
I wanted to boot with u-boot so I added:

KERNEL_IMAGETYPE = "uImage"

u-boot builds fine but when I boot up my raspberrypi, u-boot doesnt start
the kernel.

U-Boot 2013.01-rc1 (Jul 08 2016 - 19:01:50)

DRAM:  448 MiB
WARNING: Caches not enabled

Heres is a printenv

Any help would be great. Thanks.
