+Subject: [PATCH] If FFUJ is enabled serial console must be disabled
+
+FFUJ mode user is not allowed to enter uboot command
+line interface. Serial console is disabled by creating
+an indefinite sleep if FFUJ is enabled, same
+functionality is used in whitely platforms
+
+Tested:
+Serial console is disabled in FFUJ mode
