From: Grant Likely <[EMAIL PROTECTED]> Most of the embedded board ports select CONFIG_DEFAULT_UIMAGE so that uImage files get built by default. However, the current code casues the arch/powerpc/boot/Makefile to be called with the 'uImage' target and adds 'uImage' to the 'image-y' make variable. If CONFIG_DEFAULT_UIMAGE is not set, then the boot makefile is called with target 'zImage'.
However, the zImage target already automatically causes all targets listed in 'image-y' to be built, which includes uImage. This patch makes the default build target alwasy call the boot makefile using the 'zImage' target, regardless of if CONFIG_DEFAULT_UIMAGE is set. Making this change allows multiple boot images to be built from a single kernel compile. An example of where this is useful is with the Efika and lite5200 boards. Both boards can use the same kernel image (vmlinux), but they use different boot image files (zImage.chrp vs. uImage). By making this change, the boot makefile now builds both by default so a single defconfig can be used for testing both platforms. This patch also eliminates the BOOTIMAGE variable because it doesn't appear to be used anywhere.
