R528/T113 SoCs uses the same SPI IP as the H6, also have the same clocks

is that the new SoCs do not have a clock divider inside. Instead of this
we should configure sample mode depending on input clock rate.
The pin assignment is also different: the H6 uses PC0, the R528/T113 PC4
instead. This makes for a change in spi0_pinmux_setup() routine.

For LPDDR3 support we needed to special-case one group of registers,
because for that DRAM type we need to write 0 into the lower register of
each pair. That already made the code less readable.
LPDDR4 support will make things even messier, so let's refactor that
code now: We allow to write different values into the lower and upper
half of each pair. The masking is moved into a macro, and use in each

Allwinner seems to typically stick to a common MMIO memory map for

also introduce new generations of some peripherals. The last time this
happened with the H6, which apart from re-organising the base addresses
also changed the clock controller significantly. We added a
CONFIG_SUN50I_GEN_H6 symbol back then to mark SoCs sharing those traits.
Now the Allwinner D1 changes the memory map again, and also extends the
pincontroller, among other peripherals.
To mark this generation of SoCs, add a CONFIG_SUNXI_GEN_NCAT2 symbol,
this name is reportedly used in the Allwinner BSP code, and prevents us
from inventing our own name.
Add this new symbol to some guards that were already checking for the H6
generation, since many features are shared between the two (like the
renovated clock controller).

Currently there is one DRAM parameter struct for the Allwinner H616 DRAM
"driver". It contains many fields that are compile time constants
(set by Kconfig variables), though there are also some fields that are
probed and changed over the runtime of the DRAM initialisation.
Because of this mixture, the compiler cannot properly optimise the code
for size, as it does not consider constant propagation in its full
potential.
Help the compiler out by splitting that structure into two: one that only
contains values known at compile time, and another one where the values
will actually change. The former can then be declared "const", which will
let the compiler fold its values directly into the code using it.
We also add "const" tags for some new "struct dram_config" pointers, to
further increase code optimisation.
To help the compiler optimise the code further, the definition of the
now "const struct dram_para" has to happen at a file-global level, so
move that part out of sunxi_dram_init().
That results in quite some code savings (almost 2KB), and helps to keep

The usage of the C keyword "inline" seems to be a common
misunderstanding: it's a *hint* only, and modern compilers will inline
(or not) functions based on their own judgement and provided compiler
options.
So while marking functions as "inline" does not do much, missing the
"static" keyword will force to compiler to spell out a version of the
function for potential external callers, which actually increases the
code size (though hopefully the linker will drop the function).
Change the "inline" attribute for the mbus_configure_port() functions in
some Allwinner DRAM drivers to "static", so that the explicit version
can actually be dropped from the object file, reducing the code size.
"static inline" has a use case in header files, where it avoids a warning
if a .c file including this header does not use the particular function.
In a .c file itself "static inline" is not useful otherwise, so just use
static here as well.

That is a bit tricky, since we need to do that in hand-coded AArch32
