b3cb03cf79 sunxi: Parameterize "unknown feature" in H616 DRAM driver
Part of the code, previously known as "unknown feature", also doesn't
have constant values. They are derived from TPR0 parameter in vendor
DRAM code.

Let's move that code to separate function and introduce TPR0 parameter
here too, to ease adding new boards.

ae6f66d5b5 sunxi: Parameterize bit delay code in H616 DRAM driver
These values are highly board specific and thus make sense to add
parameter for them. To ease adding support for new boards, let's make
them same as in vendor DRAM settings.

f221411caa sunxi: Convert H616 DRAM options to single setting
Vendor DRAM settings use TPR10 parameter to enable various features.
There are many mores features that just those that are currently
mentioned. Since new will be added later and most are not known, let's
reuse value from vendor DRAM driver as-is. This will also help adding
support for new boards.

f35ec2105e sunxi: parameterize H616 DRAM ODT values
While ODT values for same memory type are similar, they are not
necessary the same. Let's parameterize them and make parameter same as
in vendor DRAM settings. That way it will be easy to introduce new board
support.

456093b4a3 sunxi: remove CONFIG_MMC?_CD_PIN
For legacy reasons we were defining the card detect GPIO for all sunxi
boards in each board's defconfig.
There is actually no need for a card-detect check in the SPL code (which
consequently has been removed already), and also in U-Boot proper we
have DM code to query the CD GPIO name from the device tree.

That means we don't have any user of that information left, so can
remove the definitions from the defconfigs.

b072aefbbe sunxi: define SYS_MONITOR_LEN in Kconfig, not _defconfig
Commit 08574ed339 ("Convert CONFIG_SYS_MONITOR_LEN to Kconfig") moved
the definition of said config variable from the common sunxi header to
*every board's* defconfig.
This is a platform choice, not board specific, so remove the variable
from there, instead set the one value for all Allwinner boards in
Kconfig.

08574ed339 Convert CONFIG_SYS_MONITOR_LEN to Kconfig
This converts the following to Kconfig:
   CONFIG_SYS_MONITOR_LEN

To do this, we set a default of 0 for everyone because there are a
number of cases where we define CONFIG_SYS_MONITOR_LEN but the only
impact is that we set TOTAL_MALLOC_LEN to be CONFIG_SYS_MALLOC_LEN +
CONFIG_ENV_SIZE, so we must continue to allow all boards to set this
value. Update the SPL code to use 200 KB as the default raw U-Boot size
directly, if we don't have a real CONFIG_SYS_MONITOR_LEN value.

a514577ce2 sunxi: defconfig: Add X96 Mate TV box
The X96 Mate TV box is a TV box with the Allwinner H616 SoC. It is
available with up to 4GB of DRAM and 64GB eMMC.
The DRAM chips require a different configuration when compared to the
OrangePi Zero2, we must not use read/write training and write leveling.

Add a defconfig for the box, so that we can easily build U-Boot for it.
We synced the .dts file already from the kernel tree.
