-===== make cfg =====
-In addition to generating the appropriate ''.config'' file, you can go one step further and produce  the subsequent ''u-boot.cfg'' file with:
-<code>
-$ make cfg
-</code>
-Relevant entries that define the remainder of the build:
-<code>
-#define CONFIG_SYS_CPU "armv7"
-#define CONFIG_SYS_CONFIG_NAME "zynq-common"
-#define CONFIG_BOARDDIR board/xilinx/zynq
-#define CONFIG_CPU_V7A 1
-#define CONFIG_SYS_VENDOR "xilinx"
-#define CONFIG_SYS_ARCH "arm"
-#define CONFIG_SYS_BOARD "zynq"
-#define CONFIG_SYS_ARM_ARCH 7
-#define CONFIG_ARM 1
-#define CONFIG_ARCH_ZYNQ 1
