[U-Boot] [PATCH] wandboard: Set default environment to use zImage

[Otavio Salvador]

From: John Weber <rjohnweber at gmail.com>

Change the default environment to use zImage instead of uImage,
because using zImage does not require a LOADADDR assignment when
building the kernel to be consistent with the loadaddr environment
variable in u-boot, decreasing the chance for error.  This requires
changes to the default environment to load a file named zImage
instead of uImage, and to use the 'bootz' command instead of 'bootm'
when booting the kernel.

The zImage works for FSL Linux's kernel fork versions 3.0.35, 3.10.9,
and 3.10.17; this also works fine for mainline kernels.  There is no
reason to continue using uImage for default environment.
