OrangePi Zero2 is SBC based on Allwinner H616 with 1 GiB of RAM, SD card
support, gigabit ethernet, micro HDMI, WIFI, Bluetooth and 1 USB 2.0
port. It also has two GPIO headers which allows further peripherals to
be used.
The devicetree file is taken from v3 of the OrangePi Zero2 Linux

sunxi: Add support for H616 SoC
H616 is very similar to H6 so most of the infrastructure can be reused.
However, two big differences are that it doesn't have functional SRAM A2
which is usually used for TF-A and it doesn't have ARISC co-processor.
It also needs bigger SPL size - 48 KiB.

mmc: sunxi: Refactor mod clock register offset
So far the only difference between the various Allwinner MMC controller
we are concerned about is the mod clock register offset.
This is actually not directly related to the MMC controller IP, but an
integration choice, dependent on the SoC this appears in.
To avoid becoming trapped with some compatible fallback strings, let's
remove the whole struct sunxi_mmc_variant, and replace this with a SoC
based choice, which we can derive from the CONFIG_MACH_SUNx_y symbols.
This will later simplify H616 support.

By default the echo command emits its arguments followed by a line feed.
If any of the arguments contains the sub-string "\c", the line feed is
suppressed.
This does not match shells used in Linux and BSD where the first argument
has to be -n to suppress the line feed.
The hush shell interferes with the parsing of backslashes. E.g. in the
following command line quadruple backslashes are required for suppressing
the line feed:
for i in 1 2 3; do for j in 4 5; do echo \\\\c ${i}${j}; done; echo; done;
To avoid unexpected behavior the patch changes echo to use -n as first
argument to suppress the line feed.
