The MCR3000 board is equipped with an AM29LV160DB boot flash which

- One 16kb block
- Two 8kb block

The environment being quite tiny, we save one 64kb block by embedding

Commit 7653942b10e9e ("common/env_embedded.c: drop support for

used in linking scripts to allow fine placement of embedded

This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:

This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a

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.

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.

spl: fix binman_sym output check

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.

Commit 286ede6 ("drivers: core: Add translation in live tree case") made
dev_get_addr always use proper bus translations for addresses read from
the device tree. But this leads to problems with certain busses, e.g.
I2C busses, which run into an error during translation, and hence stop
working.

It turns out that of_translate_address() and fdt_translate_address()
stop the address translation with an error when they're asked to
translate addresses for busses where #size-cells == 0 (comment from
drivers/core/of_addr.c):

 * Note: We consider that crossing any level with #size-cells == 0 to mean
 * that translation is impossible (that is we are not dealing with a value
 * that can be mapped to a cpu physical address). This is not really specified
 * that way, but this is traditionally the way IBM at least do things

To fix this case, we check in both the live-tree and non-live tree-case,
whether the bus of the device whose address is about to be translated
has size-cell size zero. If this is the case, we just read the address
as a plain integer and return it, and only apply bus translations if the
size-cell size if greater than zero.
