SD Image Build Support

To settle this in the most laziest way HAHA =]

@ Makefile

$$(PL_PROJ_$1)/images/linux/system.dtb: $$(PL_CONFIG_$1)
$$(PL_ENV_$1) petalinux-build -c device-tree -p $$(PL_PROJ_$1)

ADD copy kernel driver HERE, add tab remember

$$(PL_PROJ_$1)/images/linux/$$(KERNEL_$$(ARCH_$1)): $$(PL_CONFIG_$1)
$$(PL_ENV_$1) petalinux-config -c kernel -p $$(PL_PROJ_$1)
$$(PL_ENV_$1) petalinux-build -c kernel -p $$(PL_PROJ_$1)

Manually configure the driver to embedded or module now all set =]
