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.

Also note that to get clean build for HSDK we need to disable

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.

This situation turns out to lead to a run time freeze with certain

Derive this seed only when the randomizer is enabled (and conf->nseeds

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'

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.
