Clock Driver
This driver is ast2500-specific and is not compatible with earlier
versions of this chip. The differences are not that big, but they are
in somewhat random places, so making it compatible with ast2400 is not
worth the effort at the moment.
SDRAM MC driver
The driver is very ast2500-specific and is completely incompatible
with previous versions of the chip.
The memory controller is very poorly documented by Aspeed in the
datasheet, with any mention of the whole range of registers missing. The
initialization procedure has been basically taken from Aspeed SDK, where
it is implemented in assembly. Here it is rewritten in C, with very limited
understanding of what exactly it is doing.

- no audio

The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.
Main changes:
* Brought in the correct Tegra210 CAR binding; the old file in U-Boot
appears to be a renamed version of the Tegra124 bindings rather than
the real Tegra210 version.
* Conversion of SPI and UART nodes to standard DMA bindings. U-Boot
doesn't use DMA so isn't affected.
* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
information required by U-Boot, so U-Boot is not affected.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot, including separation of the
Tegra LIC (Legacy IRQ controller) and GIC.
* Node sort order fixes.
Remaining deltas relative to the Linux DT:
* U-Boot has enabled PCIe for Tegra210, but the kernel hasn't yet.
* The GPIO node compatible value in the kernel explicitly includes
Tegra124 values whereas U-Boot does not. I'll send a kernel patch to
correct this.

The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.
Main changes:
* USB phy_type property is aligned with the kernel, so board files are
updated so the final DT content doesn't change. I'm not convinved that
Nyan uses HSIC phy_type. However, I'd rather this change be a no-op,
and any DT bug-fixes be separate.
* Sync misc changes from the kernel: missing DT content, minor compatible
value fixes, typos.
Remaining deltas relative to the Linux DT:
* U-Boot uses #address-cells/#size-cells of 1 whereas the kernel uses 2.
I believe U-Boot's DT parsing currently assumes that these values match
the physical address size, so I didn't synchronize this part of the DT.
* U-Boot uses the original XUSB PHY DT binding, wherease the kernel DT
has moved to a newer version. Thus, XUSB client nodes include properties
names phys and phy-names that do not appear in the kernel, and don't
include pad definitions in the padctl node.

This patch includes the latest DT sources for socfpga from the current
Linux kernel. And enables CONFIG_OF_CONTROL for the new build target
"socfpga_socrates" (the EBV SoCrates board) to make use of this new DT
support.
Until this patch, the only SoCFPGA U-Boot target in mainline is
"socfpga_cyclone5". This build target is not (yet) changed to support
DT. So nothing changes for this target. Even though the long-term
goal should be to move all SoCFPGA targets over to DT.
One of the reasons to enable DT support in SoCFPGA is, that I need to
support multiple different SPI controllers for this platform. This is
the QSPI Cadence controller and the Designware SPI master controller.
Both are implemented in the SoCFPGA. And enabling both controllers is
only possible by using the new driver model (DM). The DM SPI code
only supports DT based probing. So it was easier to move SoCFPGA to
DT than to add the (deprecated) platform-data based probing to the
DM SPI suport.
Note that the image with the dtb embedded is u-boot-dtb.img. This needs
to be used now for those DT enabled boards instead of u-boot.img.
