Since the dawn of time for the Allwinner support in mainline U-Boot
we store the environment to the SD card and write directly at
544KB from the beginning of the device. This leads to problems when
the U-Boot proper image grows beyond 504KB and eventually overlaps.
With one release of having the environment preferably in a FAT
partition, let's now turn off the MMC variant fallback, so we get back
all the space we need to implement features.

net: sun8i-emac: remove support for old binding
The original DT binding used by U-Boot's sun8i-emac driver was not really

binding, we can remove support for the old DT nodes from the driver.

net: sun8i-emac: add support for new EMAC DT binding
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.

net: sun8i-emac: support new pinctrl DT bindings
The Linux kernel driver for the Allwinner pin controller gained support

The sun8i-emac Ethernet driver for new Allwinner MACs reads the pins from

The sunxi GPIO driver is missing some compatible strings for recent

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.

With the most recent tools for ARC (arc-2017.09) in case of

That happens because the compiler doesn't handle "naked" functions
as a special case where stack calculation shouldn't be done.
But for now until this is fixed in GCC to get clean buildman output
we're disabling stack-usage check for ARC.

More ARC changes and fixes for v2018.05
* Update of ARC tools to the most recent arc-2017.09
* Fix for compile-time warning for AXS10x
* Add support of platform-specific commands for HSDK
* Add support for on-board SPI flash on HSDK
Note though that for write support another series [1]
is required. I hope that Jagan will be able to review and
act on SPI flash improvement series before we get beyond RC1.
Also note that to get clean build for HSDK we need to disable
stack-usage check [2] as our current GCC erroneously tries to calculate
stack-usage on a naked function which leads to warning.

due to defines quite often being multiplications of values/other defines

spl: nand: sunxi: use PIO instead of DMA
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.
