[PATCH 0/8] sunxi: Update H616 DRAM driver

[Jernej Skrabec]

Current H616 DRAM driver is completely customized to Orange Pi Zero2
board, which is currently the only H616 board supported by U-Boot.
Needless to say, this is not ideal for adding new boards. With changes
in this series, all DDR3 boards are supported and all that is needed is
just vendor DRAM values extracted from Android image. New DRAM types
should also be easier to support, since a lot of constants used before
are not really DRAM type dependent.

Changes were verified by decompiling driver and generated values were
compared to previous, hard coded ones. This was done without dram_para
structures, so compiler was able to heavily optimize code and produce
constants.

Please take a look.

Best regards,
Jernej
