 Notes:
 -----
-	The latest ddr initializer for the rk3308 platform (currently only
-	used by the rock-pi-s machine) does not output diagnostic messages
-	to uart0. This causes a bunch of gibberish to be printed to the
-	console window which only becomes legible once the linux kernel
-	starts. I.e. the console output of the ddr initialization routine,
-	as well as u-boot is lost. An older version of this same binary
-	blob does, however, support output to uart0 (making its diagnostic
-	messages as well as u-boot available on the console). By default
-	the build assumes the user would like to see these message and be
-	able to have the option to interact with u-boot. Iow: for the
-	rock-pi-s an older version of rkbin is used.
