The Ethernet MAC used in newer Allwinner SoCs (H3, A64, H5) got an
upstream Linux driver in v4.15.
This one uses a slightly different binding from the original one used
by the U-Boot driver.
The differences to the old binding are:
- The "syscon" address is held in a separate node, referenced via a
phandle in the "syscon" property.
- The reference to the PHY is held in a property called "phy-handle",
not "phy".
- The PHY register is at offset 0x30 in the syscon device, not at 0.
- The internal PHY is activated when the node, which phy-handle points
to, is a child node of an "allwinner,sun8i-h3-mdio-internal" node.
Teach the U-Boot driver how to find its resources in a "new-style" DT,
so that we can use a Linux kernel compatible DT for U-Boot as well.
This keeps support for the old binding for now, to allow a smooth
transition.

The Linux kernel driver for the Allwinner pin controller gained support
for generic properties, which are now also used in the DTs.
The sun8i-emac Ethernet driver for new Allwinner MACs reads the pins from
the DT, but so far only supported the old binding.
Update the parsing routine to cope with both the old and new bindings,
so that the newer DTs can be used with U-Boot and its Ethernet driver.

The sunxi GPIO driver is missing some compatible strings for recent
SoCs. While most of the sunxi GPIO code seems to not rely on this (and
so works anyway), the sunxi_name_to_gpio() function does and fails at
the moment (for instance when resolving the MMC CD pin name).
Add the compatible strings for the A64 and V3s, which were missing
from the list. This now covers all pinctrl nodes in our own DTs.

As we are running into issues where the final U-Boot FIT image file is
exceeding our size limit, add a hint to the README.sunxi64 file
to point out the possibility of building non-debug versions of the ATF
binary. These are about 12KB smaller than the standard debug build, and
so allow successful U-Boot builds for many boards with the Allwinner H5
SoC.
Please note that under normal circumstances the debug build is still
recommended, as it gives valuable clues in case something goes wrong in
the ATF.

SPL support was first written to support only the earlier generations of
Allwinner SoCs, and was only really enabled on the A13 / GR8. However,
those old SoCs had a DMA engine that has been replaced since the A31 by
another DMA controller that is no longer compatible.
Since the code directly uses that DMA controller, it cannot operate
properly on the later SoCs, while the NAND controller has not changed.
There's two paths forward, the first one would have been to add support
for that DMA controller too, the second to just remove the DMA usage
entirely and rely on PIO.
The later has been chosen because CPU overload at this stage is not an
issue and it makes the driver more generic, and easier to understand.

One bit in the control registers indicates if the NAND controller is
ready to receive a new command. Otherwise, the command FIFO is full and
we should wait for this bit to flip. It then states that the last

In the nand_read_buffer() step, the seed is calculated by doing a modulo
by conf->nseeds which is always zero when not using the randomizer (most
of SLC NANDs).
This situation turns out to lead to a run time freeze with certain
toolchains.
Derive this seed only when the randomizer is enabled (and conf->nseeds
logically not zero), exactly like what has been done before with an
identical situation, see commit ea3f750c73 ("nand: sunxi: Fix modulo

When the requested ECC strength does not exactly match the strengths
supported by the ECC engine, the driver is selecting the closest
strength meeting the 'selected_strength > requested_strength'
constraint. Fix the fact that, in this particular case, ecc->strength
value was not updated to match the 'selected_strength'.
For instance, one can encounter this issue when no ECC requirement is
filled in the device tree while the NAND chip minimum requirement is not
a strength/step_size combo natively supported by the ECC engine.

A previous commit introduced the use of binman in the SPL.
After the binman_sym call over the 'pos' symbol, the output value is
checked against BINMAN_SYM_MISSING (-1UL). According to the
documentation (tools/binman/README), when it comes to the 'pos'
attribute:
pos:
This sets the position of an entry within the image. The first
byte of the image is normally at position 0. If 'pos' is not
provided, binman sets it to the end of the previous region, or
the start of the image's entry area (normally 0) if there is no
previous region.
So instead of checking if the return value is BINMAN_SYM_MISSING, we
should also check if the value is not null.
The failure happens when using both the SPL file and the U-Boot file
independently instead of the concatenated file (SPL + padding + U-Boot).
This is because the U-Boot binary file alone does not have the U-Boot
header while it is present in the concatenation file. Not having the
header forces the SPL to discover where it should load U-Boot. The
binman_sym call is supposed to do that but fails. Because of the wrong
check, the destination address was set to 0 while it should have been
somewhere in RAM. This, obviously, stalls the board.
