Passing phy configuration to the ep93xx_eth driver was not supported yet
and will be added with this patch. When no pdata is passed, the probably
broken default of phy_addr = 0 will be used to maintain compatibility
with the previous implementation.

PHY like the ks8721bl used on the edb9302 and similar evaluation boards
will initially not respond to the ep93xx_phy_read/write functions when
the MII-preamble is supressed. The supression is switched on by default
and must be switched off by clearing bit 8, see also EP93xx Users guide.
Removing the orphaned MII_SUPPRESS_PREAMBLE config option, note:
setting MII_SUPPRESS_PREAMBLE would actually enable the preamble transmission.

dev_request_mem_region returns a void * which shall be checked with
IS_ERR(), but in some cases the valid pointer returned clashes with
error values. This is especially the case on some Atmel SoCs.
This introduces dev_request_mem_resource which returns a struct resource
instead which in any case can be checked with IS_ERR(). It's the drivers
responsibility then to get the IOMEM pointer from the resource.

Currently all fastboot flash commands with UBI images are handled by a
final call to 'ubiformat'. This only makes sense for flash commands
where the target file is a mtd device. If we just want to transfer a UBI
image we would expect a simple copy to the correct location.
This patch checks if the destination file is a MTD device by opening it
and calling an ioctl MEMGETINFO. Only for MTD devices, ubiformat is
called.

If of_state_fixup() fails for some reason, boot/bootm will fail, too
However, it is completely unclear where the error has happened, and to
the user it rather seems like the kernel device tree loaded from some
file was broken/corrupt, not that in fact some fixup routine was
failing.

Unlike at24 (I2C), the at25 (spi) EEPROM driver doesn't check if the
device tree node contains partition definitions. This means that one
for example cannot have bootstate partitions on an at25 EEPROM, while it
works on an at24 EEPROM.
This patch adds device tree based partition support to the at25 driver.

Since commit 764ae1647c ("ARM: i.MX: Add correct SoC type detection
for i.MX6") the definition of the function cpu_is_mx6q and cpu_is_mx6dl
has changed. Before that change they match the SoM family Quad/Dual and
DualLite/Solo. After that change they are SoM specific. They match only
Quad and DualLite. There are extra functions cpu_is_mx6d and cpu_is_mx6s
for SoM Dual and Solo.
We have not seen any real world consequences of this problem yet.
