The sun4i part is fine.

Regarding the A23 part, the only nitpick from me is the newly added
CONFIG_DRAM_ODT_CORRECTION option. The description does not seem
to be very informative in Kconfig:

Since the right correction value is extracted from the FEX file (or
where are we expected to get it from?), a short instruction about
converting the 'dram_odt_en' parameter from FEX into the
DRAM_ODT_CORRECTION option for U-Boot would be quite useful here.

Other than this, looks good and
