little bit tricky, as generally it requires several binary blobs which are not
shipped in the U-Boot source tree. Due to this reason, the u-boot.rom build is
not turned on by default in the U-Boot source tree. Firstly, you need turn it
-on by enabling the ROM build:
+on by enabling the ROM build either via an environment variable
-$ export BUILD_ROM=y
+ $ export BUILD_ROM=y
-This tells the Makefile to build u-boot.rom as a target.
+or via configuration
+
+ CONFIG_BUILD_ROM=y
+
+Both tell the Makefile to build u-boot.rom as a target.
