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.
